Grinder and saw blade. Using a grinder for cutting various materials, cutting and sanding wood. Grinding and polishing discs for wood for an angle grinder

All photos from the article

Currently, an angle grinder, popularly known as an angle grinder, is deservedly considered one of the most versatile tools. Almost every good owner has it in his arsenal. With such an assistant, you can quickly and effortlessly cut, grind, polish, peel or saw almost any material with your own hands.

The secret of such unheard of popularity is the simplicity of the instrument. The instructions for the grinder provide for attaching a specific disk or attachment to a rotating shaft.

After which, depending on the purpose of the disk, you can perform certain work. The scope of application can be varied, but in this article we will focus more on cutting and processing wood.

Advice: according to most experts, it can only be used for fragmentary work. Moreover, this must be done extremely carefully, the risk of injury is too high.

General characteristics and purpose of disks

The range of this product is simply huge; there are dozens of types of products in each sector. But all this mass can be divided into several main directions.

Types of disks

• Circles or discs with abrasive coating intended for grinding and polishing various surfaces. Since wood is not polished, a wood grinding disc for an angle grinder is used in this sector.
• Diamond-coated wheels are more used in construction; they can be segmented or solid. They are used to cut particularly durable materials, such as stone, concrete monolith and, in some cases, metal. Such products are not used for carpentry work.

• Saw blades for wood for an angle grinder are practically no different visually from saw blades for 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.

• Regardless of the purpose, all circles have several standard diameters. Most small disk on wood for an angle grinder 115 mm. But the most popular is considered to be a 125 mm wood disc for an angle grinder.

• Wood is a specific material, so you should not use circles designed for cutting concrete or metal.. These materials require high strength and high speed, such a circle can simply get stuck in a tree, which will lead to its destruction or burn your grinder.
• The shaft diameter in all modern angle grinders for wood is standard and is 22.2 mm. But, in the recent past, there have been several gradations, so you should pay attention to the labeling. For example, a wood saw blade for an angle grinder 125x22.2 mm can be installed through an attachment on the thin shaft of an outdated machine, but if the shaft is thicker, your circle will be useless.

Important: The maximum diameter of the manual angle grinder 230 mm. So, even if you manage to find a wood cutting disc for a 230 mm angle grinder, it is better to refuse its installation and use. The fact is that the larger the diameter, the higher the likelihood of injury, especially when working with wood.

Cutting wheel

Due to the fact that this tool has high speeds and cannot be firmly fixed in the hands, high-strength tungsten carbide is used for such circles, which is why their price is respectable.

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.

Wood is a specific heterogeneous material that requires special wheels to work with. Grinder discs for metal are absolutely not suitable for cutting wood! Otherwise, the disk may be destroyed during operation.

The saw blade for wood for an angle grinder is the same as for a circular saw, but with a smaller diameter. In most cases, discs with a diameter of 115 mm and 125 mm are used, which can be purchased in our online store.

Attention! Working with a saw blade is extremely dangerous and requires angle grinder skills and great care. When sawing, the blade may jam in the wood, which will lead to the tool being torn out of your hands and serious injury. It is strictly forbidden to cut wood with an angle grinder. The tool must be securely fastened to the table.

Choosing a saw blade for an angle grinder for wood

When choosing saw blade for wood, pay attention to the shape of its teeth, which can be variably beveled, straight and trapezoidal. In our online store you can buy wood wheels for an angle grinder with variable beveled teeth with a diameter of 115 and 125 mm. They are suitable not only for cutting wood, but also for cutting aluminum and laminate.

Another factor worth paying attention to is the number of teeth on the disc. The higher the tooth frequency, the cleaner the cut will be.

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 under standard sizes Bulgarians 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.

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.

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.

At angle grinder work With wood processing discs, it is important to pay attention to the following points:
1. Choose the right circle for the tool: by outer and seat diameter, and also depending on the type of wood.
2. Select the appropriate operating mode for the tool.
3. Do not use circles that have obvious signs damage.
4. Resort to the use of personal protective equipment.

Do not carry out work without using a protective casing, with the exception of peeling, grinding and polishing operations. 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;
• planers;
• 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 saw blade for wood for an angle grinder, you can solve a fairly large number of different problems 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.

Saw blades trademark Rapide 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 operation disc 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.

Inner diameter of such a circle - the seat - is 22.2 mm, which corresponds to seat angle grinder (grinder). O.D wheel - 180mm and the use of a wheel of this size is provided for by an angle grinder exclusively of the corresponding 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.

Wood disc for grinder 180mm 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 from wooden beam.

Characteristics of saw blade for wood 180 mm:

Country of origin	Germany

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 for an angle grinder 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 thin boards. 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 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. Vary cutting tools by number and shape of teeth:
1. beveled;
2. straight;
3. in the shape of a trapezoid.

The first variant of the tooth shape is considered universal. It is suitable for any type of wood for small amounts of work. When sawing wood from soft varieties It is quite possible to use grinder discs 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 if process provides for 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 an angle grinder 125 mm 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. The best option would 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. For finishing and polishing wooden surfaces, various types of attachments can be used:
1. cord brushes;
2. end circles;
3. petal nozzles;
4. sanding wheels;
5. 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 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 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 wide range of 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.

Wood grinding discs for 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 eliminate paint and varnish materials from wooden surfaces. It is important to note that most often such attachments are used to remove paint and rust from metal pipes.

Pay attention! 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 wood

Wood sanding discs equipped with wire coils are also used for brushing. This event allows you to give the wood an unusual look and artificially age it.

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.

Use petal circle allows for rough processing of workpieces made of different materials. It can also be used for finishing sanding. Fine-grained petals are used for finishing.

Today you can find another variety grinding discs to Bulgarian. 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 softest wood treatment. For polishing work, 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 and varnish from the surface of the material. It should be understood that top 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 surfaces in the manufacture of unique interior products. The surface is processed with soft particles of wood, 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:
1. Correct selection of circle size.
2. Installing a wood disc for an angle grinder.
3. Selecting the appropriate operating mode of the machine.
4. Avoid using damaged circles.
5. Use of personal protective equipment.
6. 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 grinding tree. It assumes the possibility of successfully leveling the wood, giving the optimal shape to the 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.
• Petalaceae grinding attachments- This is the most popular option for consumables used. 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 you not only to carry out high-quality wood processing, but also to give a perfectly smooth surface comparable to a mirror.
• 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 wood processing devices perform specific tasks, but the grinding wheel sometimes surprises with its versatility and high level of efficiency.
• A chain disk for wood is one of the most productive, but crude ways of processing natural material.

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 required special nozzles and discs that allow you 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. Improper 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.

Pay attention! 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 of wood material with using angle grinders 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.

An angle grinder can be used for processing wood, but before you start using it, you should study the technical features of the various attachments. 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.

An angle grinder, if you know and correctly use all its capabilities, is a truly universal device that can be used on almost any material. And if we are talking about processing wood on a large scale, then the “grinder” is much more effective than hand-held abrasive tools and devices. The main thing is to choose the right nozzle. This article will help you understand their main modifications and specific application.

Rough stripping of wood

Disc plane

This attachment almost completely replaces this hand tool.

An irreplaceable thing if, for example, you need to rough-process a log - when erecting a log house, preparing fence supports, and so on.

Features of application:

• In this case, the protective cover can be removed. This nozzle is solid and does not collapse. But protection from flying wood chips (glasses, thick clothing, mittens) is required.
• It is allowed to work only with a grinder, in which a second handle is provided (or installed). The angle grinder must be held with both hands when roughing wood.

Roughing disc

The main purpose of such attachments is to remove bark from wood and trim the workpiece. If the “grinder” is in skillful hands, then with such a device you can make a selection of material. For example, if it is necessary to cut out a bowl. If it is being built log house, then an angle grinder with such an attachment perfectly replaces a carpenter’s axe.

In some cases abrasive disc cutting can be done. True, the cut will be wide, and there will be a lot of waste (shavings, sawdust).

Milling

Discs

These nozzles are available in various designs. The main difference between the devices is the size of the abrasive grains.

In terms of specific application, they are not much different from rasps. The only difference is the speed of the technological operation. With certain skills, it is advisable to use these for finishing wood.

Milling cutters

They exist, and especially for wood. The assortment is significant, since nozzles of this type differ in the configuration, location and size of the teeth.

Purpose of cutters:

• Selection of grooves.
• Pre-alignment of edges.
• Bowl cutout.
• Sawing (for small-section wooden pieces).

Application specifics:

• When processing wood with such attachments, it is prohibited to dismantle the protective casing.
• Each product has instructions. It clearly indicates what types of work this attachment is intended for, the recommended speed of the grinder, and so on.

Sanding wood

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.

Such attachments are used sequentially, so you will need several of them to process wood. Grinding begins with a disk with a “coarse” abrasive, and gradually its grain size must be reduced. Consequently, the devices change periodically during the work on the grinder.

Grinding wheels

Most universal device to the "Bulgarian". It alone is quite enough for varying degrees of grinding. The attachment itself is a metal base on which circles with one or another grain size are attached. They are easily changed either as they wear out, or in case of moving to another area of ​​work. Therefore, only circles are consumables. The nozzle itself can be used for an unlimited time.

Application specifics:

• Sanding wood.
• Parquet scraping.
• Processing of edges and ends.
• Stripping wood before painting.

Wood polishing

For these purposes, brushes and discs are used. Their “working elements” can be made of sponge, felt, fine-grained sandpaper and a number of other materials.

The article provides examples of only the main types of attachments for an angle grinder. There are quite a lot of products in this class, so it’s easy to choose best option devices for processing any wood. The author hopes that the information provided will help the reader with this.

Note!

Wood processing also means its cutting (sawing). Sometimes, when manufacturing piece parts, you have to adjust them to the installation site even before you start grinding the sample. Some “craftsmen” (and there are many of them among friends and on the Internet) recommend using for such operations. Strictly prohibited! Here are just the main reasons why this should not be done.

• “Bulgarian” is a high-speed machine. And although the metal from which the cutting discs are made is durable, it does not withstand this mode for long. More precisely, cutting edges(teeth), which are fixed by soldering. During intensive work, they fall off and fly apart, and with great speed. The consequences are easy to predict.
• Not all discs in size (primarily, outer diameter) are suitable for installation on angle grinders. This means you will have to dismantle the protective casing. The same thing - you can forget about employee safety.
• The structure of wood (even hardwood) is quite loose. Therefore, there is a high probability that the saw blade may jam due to constant vibration. How the “grinder” will behave in such a situation, given its power and speed, no one can predict. But it’s clear that it can easily escape from your hands.
• Constant changes in mode (for the same reason - the viscosity of lumber) lead to systematic overheating of the angle grinder engine. If used this way, the grinder will not last long.

That is why wood processing with its help is carried out only superficially - rough stripping, grinding, brushing. And for cutting you should use sawing tools and mechanisms (hacksaw, circular saw, electric jigsaw, and so on).

Corner grinding machine(angle grinder), popularly known as the “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, choice perfect solution could be a real disaster. In any case, the emphasis should be placed on the purpose of the proposed equipment. Wooden structures need 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 the existing types in more detail, it is necessary to divide the range into the following categories:

1. 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.
2. 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 wheels may resemble most modern saws, however, they are made of other alloys. Initially, such goods were considered rare, but now they have spread very widely. The ideal option is 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 are used on 125 laps special demand not only among representatives 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 is strictly prohibited. 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 sanding discs for grinders on wood, you can move on to searching for suitable models that will ensure the safest and most effective processing of such valuable material as 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:

1. circle diameter.
2. wood cut depth.
3. features of the teeth (shape, number, frequency).
