Chain disk for wood for an angle grinder. Wood disc for an angle grinder: choosing the right tool. Rough stripping of wood
An angle grinder (angle grinder), popularly known as a “grinder”, is a professional universal device that is used for a variety of purposes. With its help you can carry out many works: cutting, grinding, polishing, sawing and processing various raw materials. When choosing a suitable model, you must understand its design features, assess your financial capabilities, and also consult with a specialist.
Due to the great variety existing models, choosing the perfect solution can be a real disaster. In any case, the emphasis should be placed on the purpose of the proposed equipment. Wooden structures require appropriate grinding wheels for wood grinders. The same goes for metal - it is processed only with suitable tools.
Types of grinding discs
Currently, a wide variety of grinder discs are offered for sale, and the common man may find It’s not at all easy to choose a grinding wheel for a wood grinder. To understand in more detail existing types, it is necessary to divide the assortment into the following categories:
- Abrasive type wheels. Such consumables are particularly versatile, so they allow you to carry out precise and high-quality activities with minimal resource consumption. In addition, there is the possibility of additional polishing. Due to such characteristics, abrasive type tools are among the best.
- Diamond coated wheels are very popular. Segmented and solid models are available in the market. Depending on this option, the scope of application may differ. Both solutions are capable of providing precise cutting of any materials with the highest density. These include: stone, metal and concrete products.
Grinder blades may resemble most modern saws, but they are made from different alloys. Initially, such goods were considered rare, but now they have spread very widely. Perfect option- a combination of carbide and tungsten.
Woodworking discs
If you intend to purchase a wood saw blade for bolarka, be sure to study the basic operating principle of such a device. What features should be taken into account when purchasing a blade for an angle grinder for wood?
First of all, you should pay attention to the different standard diameters. The most compact solution has a size of 115 millimeters. However, many experts prefer to buy a 125 mm wood blade for a grinder, which is explained by its great practicality. In addition, angle grinders with 125 circles are in particular demand not only among representatives of professional fields, but also among home craftsmen.
It is no secret that a material such as natural wood is a specific heterogeneous raw material, so its processing requires the use of various circles. Use classic models for metal or concrete structures Absolutely forbidden. If you don't take this into account, the tool will simply fail or burn out.
When choosing suitable products for grinding, pay attention to the diameter of the installed shaft. The standard value is 22.2 millimeters. Initially there were several divisions, so the significance of the marking remains quite large. Currently, most standard models have a diameter of 125x22.2 mm.
And although the permissible size of an angle grinder is 230 millimeters, it is not advisable to give preference to such sizes for wood processing. When handling large items, you expose yourself to the risk of dangerous damage and injury. Ideal sizes represented by a range 115×22.2 - 125×22.2 millimeters. And class 125 wheels are the most versatile, so they can be used to solve a wide range of production operations.
After carefully studying the specifics of grinding discs for grinders on wood, you can move on to searching for suitable models that will ensure the most safe and effective processing of such valuable material like natural wood.
Types of cutting wheels
When purchasing a cutting disc, take a responsible approach to choosing the “right” model and pay attention to a number of design indicators. Among them:
- circle diameter.
- wood cut depth.
- features of the teeth (shape, number, frequency).
If you want to use a cutting disc, consider the following recommendations:
To avoid making a mistake in choosing the right solution, pay attention to following features choice saw consumable tools.
- It is necessary to choose rounded cutouts that are made strictly towards the shaft.
- Optimal thickness disk is equal to two millimeters.
- The depth of the cutouts sometimes reaches 20 millimeters.
- The cutout may be empty, but in some cases it is filled with a copper compound.
Necessary equipment
In many cases, working with materials involves carrying out polishing, grinding and roughening procedures.
It's no secret that cutting wood is a very dangerous task, but even an inexperienced worker can sand solid wood. The main thing is that he has the required equipment at his disposal. Enough to deal with basic principles upcoming work, and everything will be successful.
In most cases, flap discs are used for stripping. After carefully studying the specifics of the product, you can be convinced of its functionality and effectiveness.
From the name you can understand, what are the features and operating principle of the consumable tool. His working area may have a small number of sandpaper petals. This structure may resemble fish scales. As for papers with low roughness, they provide soft sanding of elite wood species.
Quality indicators and the degree of processing are determined by the grain size of the material, so polishing and grinding are carried out taking into account the established requirements.
Despite the great popularity of petal models, you can use other consumables. For example, very good decision can become a multi-purpose sticky disk. Most modern attachments have the ability to quickly change Velcro. The cost of the adhesive discs used is much lower than the cost of solid flap discs, however low price characterized by a short service life. In any case, universal sticky models are effective both in processing and sanding the most various materials, which explains their great popularity.
Tool characteristics and work quality
Even if you purchased the most expensive polishing and grinding equipment, this does not mean that the quality of work will be maximum. What is this connected with? It's very simple: for successful processing you need to use exclusively dried wood. Raw material is unsuitable for this type of event. If you do not take this feature into account, the result may not be the most pleasant. When choosing a wood blade, make sure that the selected raw material meets established requirements and standards.
In some cases, it becomes necessary to carry out cleaning work to remove the old layer of paint, varnish or fungal formations. Good polishing and sanding tools always work the best way, however, provided that the material is prepared taking into account basic technological requirements. You must understand that polishing and grinding discs for angle grinders are not suitable for primary processing operations, so they must be equipped with additional grinding attachments.
When choosing a suitable nozzle, you will be able to feel their effectiveness in those cases where you need to carry out cleaning old surfaces, which are covered with several layers of paint. This result can be explained very simply: most nozzles are a kind of metal plate on which there are wire bristles, placed closer to the outer circumference in a radial or perpendicular manner to the disk.
Finishing operations begin in cases where the workpiece takes on preliminary shape. The final result can be determined by the types of attachments that are used to solve the problem.
An angle grinder can be used as a cutter, as well as a grinding and polishing machine. Expanded functionality is provided by using different types disks.
And so, if you are faced with the question: “how to successfully polish or sand a wood structure,” be prepared to take a responsible approach to studying the basic subtleties and recommendations. As for the tools that will be applied later, they include:
If you intend to choose the right equipment for an angle grinder, consider not only the diameter, but also many other markings. Using the inscriptions, you can clarify the exact purpose of the tool and choose the best option for your purposes.
The modern grinder is one of the most convenient and useful devices. To improve the quality of its work, you need to take care of additional attachments and discs that will make the processing of wood, metal, or any other raw material accurate and complete.
Quite often, a grinder is used to process various types of material. Some sources claim that working with wood with these power tools is strictly prohibited, while others say that it is possible, but only taking into account some nuances. One way or another, an angle grinder is used in carpentry. Therefore, the issue of using a wood cutter for an angle grinder remains relevant.
A saw wheel with chainsaw chain elements allows you to cut boards whose thickness does not exceed 40 mm, but it is important to take special care. Violation of the rules can lead to injury:
- Protective covers on the instrument must not be removed. At large diameter discs exceeding the dimensions of the casing, the grinder cannot be used.
- It is necessary to operate an angle grinder in compliance with the speed indicated on the cutting tool. If they are exceeded, the chain may slip, which will lead to the scattering of its component parts.
- Wearing safety glasses and thick gloves is mandatory. It is also recommended to work in thick canvas clothing.
Working with an angle grinder installed disks, which are intended for circular saws, are prohibited. Because this poses a threat to human health and life.
This ban also applies to diamond cutting discs for concrete. They are not safe for working with wooden products because they are not designed for this. The efficiency indicator from their use is quite low, considering the cost of the disks. There is also a possibility of charring the product and simply ruining it.
And most importantly, there is a possibility of such a disk jamming at the processing site, which will lead to the tool flying out of the hands and possible injury.
With such a disc for an angle grinder, which is shown in the figure below, you should work with the utmost caution when processing wooden materials. Its design provides protection that prevents jamming of the side teeth, which contribute to the expansion of the cutting width. The disk has a diameter of 115 mm, and thanks to its dimensions it is possible to work with a protective casing installed.
Some home-grown “masters” practice adjusting standard saw blades For circular saw for an angle grinder. All work is carried out with the protective covers removed. Often the ending of such experiments is quite tragic. The unfortunate masters receive serious injuries that pose a threat to life.
But despite this, construction markets are full of offers that allow you to purchase. Inexperienced craftsmen are convinced by sellers that when correct use there are no risks with such instruments. All this is true, exactly until the moment when nothing bad happens.
No professional stores will ever sell a person a disc for an angle grinder that may also be suitable for working with a circular saw. For such sales, if the buyer is injured, the seller may be subject to criminal liability.
A list of the main reasons why using a circular saw to work with an angle grinder is unacceptable:
- The discs are designed to work at low speeds; the material of such a cutter is quite fragile. During operation, there is a possibility of the tool scattering into small parts or the teeth soldered on the disk breaking off, which fly off at great speed;
- Wood has a rather viscous structure, and therefore the teeth bite in an uneven manner, which leads to vibrations and mobility of the tool. This may result in loss of control of the angle grinder and may result in serious injury;
- Discs become jammed during the work process when processing wood, and the tool can be torn out of your hands. Please note that turning on a spinning disc tool is unpredictable.
- Uneven loads caused by working on a wooden surface can lead to overheating of the power tool, which will lead to its breakdown.
The optimal solution is to manufacture a stationary sawing machine on which the grinder will be securely mounted. It’s absolutely not difficult; you only need to prepare the basic components for this equipment. But it is definitely worth it; you will not only reduce the time for processing products, but also protect yourself from bad consequences.

We carry out rough processing of wood with a grinder
But, despite the existing warnings, it seems possible to process a wooden blank with an angle grinder. This requires the use of special attachments that are manufactured under production conditions, and strict adherence to safety rules when working with the tool.
Using plane discs for an angle grinder
Rough processing of a log house involves the use of special discs that allow it to perform the function of a plane. This method of processing wood using an angle grinder is considered one of the safest if you follow the operating instructions. The device is a good alternative to a carpenter's axe.
The nozzle is used without installation protective covers, since the fact that it can collapse during operation is completely excluded. You cannot use such a disk if it is in an upward position.
When using an angle grinder, it is imperative to install a handle on it, which will allow you to hold the tool with both hands.
It is also necessary to have thick overalls and equipment personal protection that can protect exposed skin. When cleaning wood, you may encounter large chips flying away, which can easily injure your skin. One of the positive side effects The ease of chopping chips or large sawdust, if necessary for household needs, is considered to be a benefit from using such a power tool.
Application of grinding discs
To remove bark from a tree trunk and give it a primary shape for workpieces, a number of special peeling attachments for an angle grinder are used.
Thanks to this chain circle it becomes possible to strip the trunks of bark or small knots. The blank material is also given the required shape for further processing using a more precise tool. Such devices can replace axes for cutting out bowls in logs for the construction of log buildings.
It is also possible to use this disc as a cutting wheel, but the resulting cut will be jagged and the loss of material will be too high due to the large thickness of the cut.
Using cutters on an angle grinder for working with wood
Having completed rough processing, you should proceed to the next processing step. wooden blanks- for milling. For this purpose, some types of special nozzles are used.
The size of the abrasive on the discs can be completely different. Using this cutting tool, its purpose should be taken into account. Using such cutters, it is easy to give final form blanks. Some craftsmen use such attachments to finish wood, and the results from such work are quite good.
Almost similar types of discs are a mechanized rasp. They are considered relatively safe instruments that do not require special precautions or certain conditions. You just need to take care of protecting your eyes and respiratory organs.
If you need to carry out regular cutting of wood materials, then it is better to use simple circular, chain and reciprocating saws, rather than a grinder. The task can also be effectively completed with a jigsaw.
It is worth noting that the alternative electric tools homemade equipment is used for cutting boards and logs. Manufacture to Execute simple tasks quite simple, thanks to which it is not at all necessary to use dangerous and expensive tools for simple tasks.
Milling wood with a grinder: what cutters can be used
This requires careful adherence to safety precautions. Such work with a milling cutter using an angle grinder is classified as dangerous, but acceptable when correct execution relevant recommendations.
A milling cutter on a grinder for working with wood is used for making grooves, rough leveling edges, cutting out bowls for log houses, and even for cutting workpieces. You can use only those cutters that have a special design that eliminates the process of jamming and tilting of the power tool due to the heterogeneity of the wood. When using, it is recommended that you read the instructions, in particular about the sections with maximum speeds and the direction of movement of the cutter in relation to the position of the angle grinder.
Milling attachments for angle grinders are not inferior in their range to attachments for manual milling devices. Naturally, it is almost impossible to achieve a similar quality of material processing with an angle grinder, but selecting suitable attachments to give the product a suitable shape is quite possible.
Video “Is it possible to cut wood with an angle grinder?”
Video review about using a grinder for cutting boards and beams. How to properly cut wood with an angle grinder and whether it can be done - you will learn in this video.
The angle grinder is very useful tool, which can be used in various areas of production. It is thanks to its versatility that it has become widespread both in industrial facilities, and at the household level.
Types of attachments for wood
Only angle grinders with speed control are suitable as a tool for wood carving. Since the main purpose of the grinder is grinding homogeneous materials, the processing of the heterogeneous structure of wooden materials must be approached very carefully.
The following types of wood circles can be distinguished:
- Wood saw for grinder
- Cutting discs
- Planers
- Grinding
Each of these parts must be used for its intended purpose.
Saw blades
A wood saw blade for an angle grinder consists of a metal circle with a chain attached to the edge. Design of special sawing tools similar to those used in chainsaws. But saw blades are made from tungsten carbide. When a grinder blade for wood hits a solid obstacle in the wood - knots, resin, metal, its base rotates without destroying the chain. Chain attachments You can quite simply strip the logs of knots and bark and give them the required original shape.
Cutting discs
Various manufacturers produce and cutting wheels for wood specifically for angle grinders, for example, a Bosch cutting wheel. Their design differs significantly from the design of circular saw blades. They usually have side teeth that protect the nozzle from jamming. Cutting tools differ in the number and shape of teeth:
- beveled;
- straight;
- in the shape of a trapezoid.
The first option for the tooth shape is considered universal. It is suitable for any type of wood for small amounts of work. When sawing soft wood, it is quite possible to use grinder blades for wood with straight teeth. Trapezoidal teeth are capable of processing fairly hard wood products: chipboard, fiberboard, OSB boards.
In addition, cutting wheels vary in diameter. Minimum size– 115x22 mm. The most commonly used circles are 125 mm in diameter; they are universal and suitable for a wide range of work. The maximum possible size is 230 mm. But it is undesirable to use the latter option when working with wood, as the likelihood of injury increases. Depending on the selected size, the depth of the wood cut will also be different.
Discs - planes for grinders
Maybe using an angle grinder as a plane. For this purpose, special circles are used - planes. Working with such attachments is allowed without a protective casing, since solid discs are not destroyed. Many brands of wheels can be sharpened many times. Before using the grinder, you need to install an additional handle to more securely hold the tool with both hands.
Sanding discs
This type of circle allows you to use the machine for its intended purpose. For finishing and polishing wooden surfaces Various types of nozzles can be used:
- cord brushes;
- end circles;
- petal nozzles;
- sanding wheels;
- roughing attachments.
Rough processing of wood is carried out using special cord brushes. End discs are designed to align the edges of parts, which is often required when making bevel cuts on workpieces. They are an excellent substitute for a file.
The widest range of grinding attachments is for flap wheels. Depending on the size of the abrasive grain, the surface of the wood can be cleaned with varying degrees of sanding. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved. The system of trapezoidal petals, which are laid with a three-quarter overlap on each other, has fairly slow wear. If the relief surface wooden product complex, then petal discs with a radial arrangement of abrasive strips are used.
Using sandpaper or sandpaper on a special attachment allows you to sand quite large areas wooden surfaces. The ability to quickly change the sanding coating makes these attachments universal.
When removing old paint coatings, stripping attachments are often used. Typically this is a wire brush attached to a metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for attaching the bristles to the perimeter of the disc.
When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, it must be cleaned back to healthy wood.

The three carbide teeth are made of tungsten carbide and are positioned at an angle of 5° to the tool base made of steel. Thanks to this design and the special shape of each tooth, the cutting surface is very clean and smooth. A disc for the Graff Speedcutter grinder is being manufactured, measuring 125x22.23x3 mm. The cutting width of the wood is 3.8 mm.
Graff Speedcutter wheels are intended for artistic wood carving, cleaning and sanding various types of wood. They are also used for cutting and selecting grooves in wood, its transverse cutting and longitudinal cutting. It is possible to use such attachments when processing parts made of aerated concrete and aerated silicate, fiberboard, chipboard, laminate, and plasterboard.
Rules for working with the tool
Any tool can pose a serious danger if the instructions for use in a specific situation are not followed. A grinder for cutting wood is no exception in this sense. The main points that are necessary when working with grinder discs – angle grinders for wood:
- Choosing the right circle size
- Installing a wood disc for an angle grinder
- Selecting the appropriate operating mode for the machine
- Avoid using damaged circles
- Use of personal protective equipment
The size of the nozzle should be installed under the protective cover of the machine without any problems. If this does not work, do not remove the protection. When working on wood with an angle grinder, you must use only special wood wheels for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or damage to the tool. To avoid destruction of the wood disc for an angle grinder, rpm grinder must correspond to those indicated on the surface of the circle. Before starting work, you should check the wood disc for defects and damage. If they are present, then it becomes dangerous to use. When working with the tool, it is necessary to wear eye and hand protection. It is best to use thick overalls.
When working with wooden surfaces, the question arises whether the disc is suitable for an angle grinder when working with wood. Today the grinder is used when performing different operations, because it was made a universal tool.
With this device you can grind, polish, cut, saw and perform many more functions. It also copes well with materials such as wood, but before work you need to study some recommendations.
In this article we will talk about discs for angle grinders, their types and attachments used when working with wood. There are many of these components for grinders and they all differ in purpose and characteristics.
Initially, you need to decide on the tool you plan to use to cut wood. It is known that discs are produced to fit standard sizes of angle grinders. The smallest diameter is 115 mm, but such a tool is used in extreme cases.
The main advantage of such an angle grinder is its compactness, but working with such a tool for a long time is extremely inconvenient. The best option for woodworking is a grinder with a 125 mm disc. It is this size of circle for wood that is the safest, which is why it has become widespread.
To operate an angle grinder on wood, a special disc is required. It is strictly contraindicated to cut wood with abrasive or diamond wheels. This will not help cope with the task, but rather will lead to destruction or overheating of the tool.
It is prohibited to operate an angle grinder with discs installed that are intended for circular grinders. Because this poses a threat to human health and life.
When choosing a circle for an angle grinder on wood, it is important to pay attention to the internal diameter of the shaft, which according to the standard is 22.2 mm.
Outdated models of angle grinders may have a different shaft diameter, so this point is important to consider when purchasing the appropriate wheel.
The optimal wheel for woodworking has following parameters: 125x22.5 mm. Grinders for discs of 150 mm and above are not recommended for use on wood, as the risk of serious injuries increases. It is better to use tools with 125 or 115 wheel diameters for cutting or sanding wood.
Not only power tools, but also hand ones, pose a serious danger if safety rules are not followed. The attachment for a grinder for cutting wood in this case is no exception.
- When operating angle grinders with discs for wood processing, it is important to pay attention to the following points:
- Choose the right circle for the tool: by outer and seat diameter, and also depending on the type of wood.
- Select the appropriate operating mode for the tool.
- Do not use wheels that show obvious signs of damage.
- Resort to application individual funds protection.
You should not carry out work without using a protective casing, with the exception of manipulations such as scraping, grinding and polishing wooden surfaces. It is especially dangerous to work with saw wheels. It is strictly forbidden to install discs from circular saws or other tools on angle grinders.
For an angle grinder, you can only use consumables that are directly intended for it. In conclusion, it should be summed up and noted that grinder wheels for wood processing are no less popular than abrasive wheels. After all, the use of such consumables greatly facilitates human work and also saves time.
- The following types of wood circles can be distinguished:
- wood saw for an angle grinder;
- cutting discs;
- planes;
- grinding.
Each of these parts must be used for its intended purpose.
A wood saw blade for an angle grinder consists of a metal circle with a chain attached to the edge. The design of special sawing tools is similar to those used in chainsaws. But saw blades are made from tungsten carbide.
When a grinder blade for wood hits a solid obstacle in the wood - knots, resin, metal, its base rotates without destroying the chain. Using chain attachments, you can quite easily strip logs of knots and bark and give them the required original shape.
- Features in working with saw blades are determined by the following factors:
- The thickness of the circle should be within 2 mm.
- The depth of the cuts made can be within 20 mm.
- The cutouts can be empty or filled with copper.
Using a wood saw blade for an angle grinder, you can solve quite a large number of various tasks related to construction, repair work, furniture production and garden landscaping.
Saw blades for wood for an angle grinder are visually practically no different from circles for a circular saw. But they are made of a completely different metal. Until recently, these products were rare; now a lot of high-quality tungsten carbide wood wheels have appeared on the market.
Important: under no circumstances even try to install a circle from a circular saw onto an angle grinder. Theoretically, this can be done through an adapter, but circular discs are designed for low speeds and on an angle grinder, in the vast majority of cases, they become warped or simply fly apart.Rapide brand saw blades are made of high-quality tool steel and are highly wear-resistant. The carbide teeth of this disc are equipped with tungsten carbide tips and have high-precision sharpening.
Rapide 180mm wood saw blades have 36 or 60 alternately set teeth, which, after long-term use of the blade, can be sharpened using special equipment.
This design allows you to successfully cut chipboard, MDF, laminated panels, hard and soft wood, obtaining a very clean and even cut. The Rapide 180mm saw blade has special temperature slots that serve to cool the blade and prevent it from overheating.
The internal diameter of such a circle - the seat - is 22.2 mm, which corresponds to seat angle grinder (grinder). The outer diameter of the circle is 180mm and the use of a circle of this size is provided for angular grinder exclusively of the appropriate diameter - 180mm.
Using this disc on any other power tools not specified by the manufacturer, or on angle grinders of a different diameter is extremely dangerous and can lead to serious injury.
One of the important advantages of Rapide saw wheels is the ability to use them for various types of cuts - both transverse and longitudinal. The manufacturer recommends the permissible number of revolutions up to 80 meters per second.
The 180mm wood grinder blade is quite popular among professional craftsmen for various carpentry works, cutting branches, logs and cutting firewood. This circle is often used in the production of furniture, the manufacture of any structures or buildings made of wooden beams.

Chain saw blades for wood: advantages of use
In this case, the saw blade is made using a chain from a chainsaw. This attachment is the most suitable for working with wood, as it has the greatest efficiency.
A chain disk for wood grinders is also considered the safest. The use of this attachment significantly reduces the likelihood of injury if the tool jams.
If the disk hits a hard element of wood during operation (for example, a knot), the chain is not destroyed. This happens by turning the base. Such attachments are very popular when it is necessary to strip a tree trunk of bark and knots.
Wood saw blades for angle grinders with a chain are used for various types of work. With their help you can remove tree branches, as well as cut boards of small thickness. The functionality of chain products allows them to be used as roughing tools. They do an excellent job of removing bark.
Using a saw wheel you can make an even cut parquet board, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material that will be processed with such a nozzle should be no more than 4 cm. Otherwise, there is a high probability of the device overheating.
Various manufacturers also produce cutting wheels for wood specifically for angle grinders, for example, the Bosch cutting wheel. Their design differs significantly from the design of circular saw blades.
- They usually have side teeth that protect the nozzle from jamming. Cutting tools differ in the number and shape of teeth:
- beveled;
- straight;
- in the shape of a trapezoid.
The first option for the tooth shape is considered universal. It is suitable for any type of wood for small amounts of work. When sawing soft wood, it is quite possible to use grinder blades for wood with straight teeth. Trapezoidal teeth are capable of processing fairly hard wood products: chipboard, fiberboard, OSB boards.
In addition, cutting wheels vary in diameter. The minimum size is 115x22 mm. The most commonly used circles are 125 mm in diameter; they are universal and suitable for a wide range of work.
The maximum possible size is 230 mm. But it is undesirable to use the latter option when working with wood, as the likelihood of injury increases. Depending on the selected size, the depth of the wood cut will also be different.
- If you need cutting discs for a wood grinder, you should initially pay attention to such parameters as the diameter of the circle, the depth of cut and the characteristics of the teeth. Depending on the wood material, it is necessary to use a wood saw blade with the following teeth:
- It is best to use universal or beveled saw blades for wood for an angle grinder if you plan to carry out work rarely in extreme cases, and the materials being processed can be any type of wood.
- Wood discs with straight teeth are recommended for use if the technological process involves working with coniferous and soft wood.
- Trapezoidal tooth shape suitable for cutting wood chips medium density. Most often, such a tooth is universal and suitable for sawing hard wood.
A cutting disc for wood for a 125 mm grinder is classified not only by diameter and, accordingly, depth of cut, but also by shape, frequency and number of teeth.
If you plan to use a saw blade for wood for a 125 mm grinder periodically, and you don’t know what kind of wood, you will need to cut. That the best option there will be a circle with variably beveled teeth.
For cutting coniferous species, as well as for any other soft wood, products with straight teeth can be used.
The trapezoid tooth has a wider range of uses. Wood saw blade for grinder 125x22.2 mm with trapezoidal teeth, capable of cutting medium-density wood chips. It is also easy to use on laminated particleboards, USB boards and medium-density fibreboards.
- This type of circle allows you to use the machine for its intended purpose. Various types of attachments can be used for finishing and polishing wooden surfaces:
- cord brushes;
- end circles;
- petal nozzles;
- sanding wheels;
- stripping attachments.
Rough processing of wood is carried out using special cord brushes. End discs are designed to align the edges of parts, which is often required when making bevel cuts on workpieces. They are an excellent substitute for a file. The widest range of grinding attachments is for flap wheels.
Depending on the size of the abrasive grain, the surface of the wood can be cleaned with varying degrees of sanding. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved.
The system of trapezoidal petals, which are laid with a three-quarter overlap on each other, has fairly slow wear. If the relief surface of a wooden product is complex, then flap discs with a radial arrangement of abrasive strips are used.
Using sandpaper or sandpaper on a special attachment allows you to sand fairly large areas of wooden surfaces. The ability to quickly change the sanding coating makes these attachments universal. When removing old paint coatings, stripping attachments are often used.
Typically this is a wire brush attached to a metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for attaching the bristles to the perimeter of the disc.
When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, it must be cleaned back to healthy wood.
Wood sanding disc for grinder: characteristics
With the help of a grinder you can not only cut and saw off wooden parts, but also carry out roughing work varying degrees of complexity. Modern market offers a large assortment such attachments. They are classified according to several indicators: shape, design and purpose.
Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove excess wood from end surface boards. They may have special spikes or crumbs.
Roughing discs for wood grinders are also used to level the surface of boards. Such circles are equipped with special spikes that are placed on a flat surface. This function is very useful, as it allows you to polish the boards from which the floor covering is constructed.
On sale you can find stripping products consisting of twisted wire. They are usually called brushes. There are two types of such attachments for grinders for woodworking, depending on the features of their structure. The first option provides for a base in the form of a glass to which the wire is attached. The second type is a disk with a wire fixed along the edge.
Brushes are used to remove paint and varnish materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.
Note! For wooden parts it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types of wood.Wood sanding discs equipped with wire coils are also used for brushing. This event allows you to give the wood unusual look, artificially age her.
However, with the help of an angle grinder equipped with a wire stripping attachment, only small volumes of wood can be processed. Thus, this element is not recommended for brushing on an industrial scale.
Grinding is one of the most popular processes for which angle grinders are used. Using such a tool and a set of attachments, you can carry out rough and gentle processing of metal, stone and wooden surfaces.
As a rule, grinding precedes polishing of workpieces. The attachments used in this case may consist of sandpaper or felt material.
The petal disc for grinders has become widespread. This tool consists of a circle (base), along the edges of which sandpaper petals are fixed. They may have different grain sizes. This indicator is selected depending on the nature of the work.
The use of a flap wheel allows for rough processing of workpieces from different materials. It can also be used for finishing sanding. Fine-grained petals are used for finishing.
Today you can find another type of grinding discs for an angle grinder. Some abrasive products are fixed to the base using special Velcro. To use such a circle, you need to screw it onto the tool spindle.
Polishing is the most soft handling wood. For polishing works, which relate to the final stage of turning a particular material, special felt discs are used.
And also on the tool market you can find circles, the working part of which consists of dense fabric. Grinder attachments for polishing are very popular when working with wood, as their use allows you to bring the surface of the material to the smoothest possible state.
If you decipher the abbreviation angle grinder, it is clear that finishing is the main purpose of the “grinder”.
- Cord brushes
They are used primarily for primary (rough) sanding of wood, when it is necessary to smooth out the unevenness of the sample.
- End discs
The name speaks for itself. These attachments are used to process the end parts of wooden blanks (cuts). They are especially effective if you have to deal with corner (oblique) cuts.
- Petal attachments
The most used grinding devices for grinders.
Attachment for grinder for brushing wood
Many craftsmen believe that metal brushes are used to remove rust and oxides only steel products. In refutation of this fact, products made from brass wire are popular in wood processing. The relatively low price and increased service life make the brush a direct competitor to abrasive attachments.
The main purpose is to remove paint coating from the surface of the material. It should be understood that upper layer paint can be removed by exposure to temperature; a brush is used when working in hard-to-reach places.
It is also possible to brush wood using a grinder with a brush. The process involves artificial aging of surfaces in the production of unique interior products. The surface is processed with soft wood particles, irregularities and temporary rings stand out against the general background.
Rules for working with the tool
Any tool can pose a serious danger if the instructions for use in a specific situation are not followed. A grinder for cutting wood is no exception in this sense.
- The main points that are necessary when working with grinder discs – angle grinders for wood:
- Correct selection of circle size.
- Installing a wood disc for an angle grinder.
- Selecting the appropriate operating mode of the machine.
- Avoid using damaged circles.
- Use of personal protective equipment.
- The size of the nozzle should be installed under the protective cover of the machine without any problems.
If this does not work, do not remove the protection. When working on wood with an angle grinder, you must use only special wood wheels for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or damage to the tool.
To avoid destruction of the wood disc for the grinder, the speed of the grinding machine must correspond to that indicated on the surface of the wheel. Before starting work, you should check the wood disc for defects and damage.
If they are present, then it becomes dangerous to use. When working with the tool, it is necessary to wear eye and hand protection. It is best to use thick overalls.
- So, how to carry out the polishing and sanding process when processing wood? What tools are needed for successful work?
- Brush cord. These tools are ideal for rough sanding of wood. The possibility of successful leveling of wood is assumed, with the addition optimal shape product.
- End discs make it easy to grind workpieces. In most cases, such work is required for miter cuts. Job end disc resembles the interaction of the workpiece with the saw.
- Flap sanding attachments are the most popular option used Supplies. The characteristics of the tool determine the ability to process various workpieces, including natural wood.
- Felt wheel - allows you to achieve minimal roughness in processed products. The basis is compressed wool, fine-haired, semi-coarse-haired and coarse-haired. A felt working tool allows not only to carry out high-quality wood processing, but also to give perfect smooth surface, comparable to a mirror one.
- A grinder wheel intended for grinding is often compared to a disc of the same name. It is important to note that the Velcro circle is a universal tool with a wide range of applications.
- Various woodworking tools perform specific tasks, but the sanding wheel sometimes surprises with its versatility and high level of efficiency.
- A chain disk for wood is one of the most productive, but crude methods of processing natural materials.
When choosing equipment, it is advisable to take into account not only the diameter, but also each accompanying informative designation. The inscriptions will allow you to determine the purpose of the tool and follow the recommendations during operation. Marking discs, circles and attachments for an angle grinder is a guarantee of a successful result.
A modern grinder is a convenient and effective tool. For quality work Special attachments and discs are required to effectively process wood, metal and any other material of interest.
Safety rules at work
The use of angle grinders for wood processing requires a serious approach. Incorrect operation of an angle grinder can lead to injury, so before using it, experts advise paying attention to some rules for operating the device.
For example, before replacing one attachment with another, you need to disconnect the angle grinder from the network. How to change a disc on an angle grinder? To answer this question, it is necessary to determine the type of circle. Some products are installed without removing the main nozzle. However, in most cases it is necessary to unscrew the flange holding the element.
Note! Under no circumstances should the cover, which is used for protection, be removed from the angle grinder. If the circle breaks, this element will protect your face and other parts of the body from injury from fragments.Processing wood material using an angle grinder must be carried out with protective gloves. Saw and cutting blades for wood are best used on medium (in terms of power) devices.
This can be explained quite simply: if the saw jams, then you still have a high chance of holding the tool in your hands. With a powerful device this will be much more difficult.
For cutting logs and boards, it is recommended to use attachments that have fine teeth. The smaller their dimensions, the less effort required to cut. Among other things, the likelihood of encountering hard wood fibers in the path of the disc is reduced.
Any angle grinder must be equipped with a speed controller, which must be set to the minimum position. When working with cutting discs for an angle grinder, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven and the device itself may jam.
Angle grinders can be used for processing wood, but before starting use you should study technical features various nozzles. Products used for grinding and polishing do not pose any danger and are easy to use.
Discs for cutting wood material require careful selection. During work, you must follow safety rules and not deviate from them.
Modern angle grinders, better known as grinders, are used for various technological processes during construction and renovation. When choosing a disk for an angle grinder for wood, you need to take into account the important features of not only the tool, but also the processed objects. Typically, the device is used for cutting metal. However, a large number of different disks allows you to use it to solve other problems.
First you need to decide on the tool (grinder - the correct name is chain angle grinder) with which you plan to cut the wood. It is known that discs are made to standard grinder sizes. The smallest diameter is 115 mm, but this tool is used in rare cases. The wide variety of power tools on the market are designed to facilitate various types of manual labor. If when working in a professional field specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on expensive hand tools.
To operate the machine with wood, you need a special drive. Abrasive, diamond, and carbide wheels are absolutely contraindicated for cutting. This will not help cope with the task, but rather will lead to destruction or overheating of the device.
When choosing woodworking universal accessories, you should know that there are not only cutting discs, but also grinding wheels. To clean the wood, use a circular saw blade. Working surface Such a device consists of several layers of sandpaper, which has varying degrees of roughness. The lower the roughness, the softer the grinding. Flap wheels allow for polishing that varies depending on the level of detail.
Grinding wheels and a milling cutter for an angle grinder must be High Quality, which affects not only the quality of the work performed, but also the safety of the master. Processing wet wood is prohibited, as the result of such manipulations can be unpredictable.
For roughing operations, which are often used as initial processing, special cleaning agents are used. They are necessary in order to remove a layer of paint from a painted surface.
To process with a grinder and a circular saw, you need specially designed attachments with which you can grind, polish and mill surfaces. The choice is up to the master.
You can use the following circles:
- An abrasive wheel for wood, which is used to work with various surfaces. Depending on the thickness of the circle, it can be cut and polished.
- The diamond wheel is designed for working with stone, concrete and other building materials. Such circles are divided into segmented and continuous. The first type, due to better performance and better cooling, provides improved performance. These discs can be used for small metal cutting.
- Regular circle. It should be noted that it is not recommended to use it for sawing wood products without experience. If possible, it is better to use another tool.
If you need to remove a layer of paint from a wooden surface, you need to install the attachment on the grinder. There are many on sale various options. They all differ in shape, design and specific work that can be performed using this tool.
The next cutter, due to the fact that the tenons on it are installed on a plane, allows you to level wooden surfaces - for example, if two boards on the floor in the place of the final structure are on different heights. This defect is easily eliminated, and the boards are then in the same plane.
There are circles made of twisted wire or in the form of a disk with windings of wire clamped in the central part. In addition to this, the wheel is often used to modify wood, giving it a distressed appearance. If this effect is used on wide surfaces in a professional environment, it is better to use special hand-held machines with wide parts.
For grinding surfaces there are special attachments consisting of a metal base on which an abrasive grinding ring is attached. The circle is screwed onto the angle grinder shaft and tightened with a special wrench. It is often equipped with an adapter for mounting in a drill holder or drilling machine.
To choose the right disc, first of all, you need to decide what material to work with.
Can be used:
- Thin blades (1-1.6 mm) are best suited for cutting thin sheet metals, such as car bodies. When working with thicker corners, they can cut faster, but the risk of blade damage increases significantly. In this case, it is safer to use thicker discs.
- Hard - most often used for active processing (cleaning) of welds after welding and gluing metal surfaces just before welding. They are used to remove (cut out) fasteners and protrusions on metal. They are also used in cases where the metal surface must be cleaned of rust or old paint.
- Elastic - mainly used as an alternative to metal brushes. They perfectly clean even curved metal surfaces from outdated paint and other similar coatings.
- Coarse - used for grinding metal and wood. Even the smallest welds can be smoothed out with large (largest grain) discs, but are mainly used for finer work. They remove faded top layers of wood surfaces, polish wood beams, rust and worn paint from metal.
- Abrasive - for processing concrete, diamond discs are slightly smaller, but they also have a shorter service life. Their use is justified only when it is necessary to perform a small one-time job.
- Diamond blades are used for cutting various products made of concrete and stone (paving slabs, steps, curbs, facing stones), as well as bricks of all types.
Turbo diamond discs (both regular and wave) are best suited for working with reinforced concrete and stone materials. When choosing, keep in mind that a turbo will provide a cleaner cut than a diamond wheel.
If the device has outside diameter only 125 mm, and the grinding machine is designed for 115 mm, it cannot be installed for the following reasons:
- Firstly, the discrepancy between the revolutions of the tool itself and the circle is dangerous for the user.
- Secondly, as it heats up and expands, the disc can get stuck, causing it to jerk.
The number of teeth is important. How less number, the faster the work will be, but the quality of the cut will be lower, and vice versa, a larger quantity increases the cutting time, but the ends of the resulting parts will be smooth.
With a large number of small teeth, the device will work with low efficiency. Large teeth allow you to work faster. The cost of the disc depends on the external size, number of teeth, and manufacturer. The most expensive model is with a circular saw.
For many reasons it is better to buy circles famous companies. The concept of a “quality disc” includes not only the degree of disc rupture and its abrasive properties, but also safety.
When choosing a new wheel, you should make sure that it is designed for speed. grinding machine. The permissible speed is indicated.
You need to follow the rule: the larger the rasp disk, the lower the speed. In addition, manufacturers protect the user as much as possible by releasing discs with high (sometimes double) strength. But if the disk is used more than necessary, all these measures become meaningless.
- working with a protective casing;
- protect your face and head;
- check lumber for nails and screws;
- hold the device firmly by hand;
- use an additional handle (many people hold the device with one hand);
- Do not allow the instrument to heat up, avoiding the risk of smoke.
In addition, if there are no plans for large-scale work with an angle grinder, there is no need to buy a lot of disks “as a reserve” - since the humidity in the air begins to affect the bakelite. The bond strength is noticeably reduced. It is better to get the necessary wood discs for an angle grinder (grinder) immediately before work.
