- What types of cutting wheels are there?
- Tips for work
The angle grinder, popularly known as the grinder, is a worthy and universal tool. It is this equipment that allows you to successfully perform cutting, grinding, polishing, and sawing almost any material. When choosing a grinder, it is extremely important to understand which model is recommended for use. The choice is largely determined by the main purpose of the proposed equipment. Metal and wood will require different types disks and a specific approach, since otherwise the work will not bring the desired results.
Grinder wheels: starting with market research
The assortment is amazing in its diversity. What types of grinding discs are there and how are their characteristics determined? To fully answer the question, the entire market should be divided into main areas.
- Abrasive coated wheels. This consumable tool is universal, because with its help any workpiece can be cut and polished with high quality. In addition, the possibility of polishing is assumed. It is not for nothing that this abrasive tool is considered one of the best.
- Diamond-coated grinder disc is one of the most common construction tools. These products can be segmented or solid, and each option has its own area of use. In each case, the possibility of high-quality and accurate cutting of durable materials, including stone, metal, and concrete monolith, is assumed.
- Saw blades for an angle grinder visually resemble modern models saws. However, other alloys are used to produce them. Previously, the product was rare, but now its prevalence is actively growing. Most the best option tungsten carbide grinding disc.
Taking into account the variety of modern products, you should abandon pointless and sometimes dangerous attempts to install a circle from a circular saw to an angle grinder. Any circular discs are designed for low speeds, and on an angle grinder there is a risk of distortion or destruction of the tool.
How to choose a suitable angle grinder model?
When studying modern grinder wheels, it is important to understand the basic principles of choosing consumables for an angle grinder. What aspects to take into account?
Grinding wheels come in several standard diameters. The most compact model has a size of 115 mm. However, 125 mm grinder discs are of greater practical importance. Moreover, it is angle grinders for 125 circles that are most widely used not only among professionals, but among home craftsmen.
Natural wood always turns out to be a specific heterogeneous material, therefore working with it requires special wheels. Grinder discs, which are designed for cutting metal or concrete, are absolutely not suitable for such processing. Otherwise, the grinder will be destroyed or burned by overheating.
When choosing grinding equipment, it is important to note that standard diameter the installed shaft is 22.2 mm. Previously there were several divisions, so marking still plays a role important role. Today, for example, a standard saw blade for woodworking has a diameter of 125x22.2 mm.
Although maximum size The angle grinder is 230 mm, such dimensions are undesirable when processing wood. When choosing a tool with a large diameter (from 150 mm), you run the risk of serious injury. Preferable dimensions are 115x22.2-125x22.2 mm. In addition, 125 circles are capable of coping with a fairly wide range of production tasks.
Only if you understand the specifics of the equipment used, you can learn how to correctly select discs for an angle grinder for safe and effective processing natural wood.
What types of cutting wheels are there?
Parameters that are used for classification cutting discs on wood:
- Disc diameter;
- Depth of wood cut;
- Characteristics of teeth: shape, frequency, number.
What should you consider when planning to use a cutting disc for a modern grinder?
- If cutting saw blades for an angle grinder on wood will be rarely used, and the type of wood being processed will be different, it is best to choose a model with variable beveled teeth.
- Models with straight teeth are suitable for cutting coniferous and soft wood. Such saw blades successfully process even the softest wood, guaranteeing a decent result.
- Trapezoid tooth allows universal use. When choosing such equipment, it is best to cut medium-density wood chips. If desired, you can use other types of products.
What parameters should be taken into account for successful work with wood, when are saw consumables selected?
- Rounded cutouts are required, which will be made towards the shaft.
- The optimal disc thickness is 2 mm.
- The depth of the cuts made can reach 20 mm.
- The cutouts may be empty, but in some cases they are filled with copper.
Equipment for grinding and roughing work
In most cases, working with materials involves the need not only for polishing, but also for grinding and roughing activities.
Cutting wood is a dangerous activity. At the same time, any person who has necessary equipment. The most important thing is to understand the principles of performing technological operations.
Most often used for peeling petal discs to Bulgarian. By carefully studying the specifics of the product, you can understand how functional and effective it is.
The name gives an initial idea about the features of the device consumable tool. Its working surface has several sandpaper petals. This structure is comparable to fish scales. At the same time, such low-roughness paper allows you to guarantee a soft sanding of natural wood. The quality and degree of processing depend on the grain size of the material, so polishing and grinding can be carried out in accordance with the requirements.
The flap disc for an angle grinder is quite popular, but if desired, you can use another consumable tool.
For example, the sticky universal disc deserves attention. Modern attachments for grinders provide the ability to quickly change Velcro. The price of the adhesive discs used for basic operations is lower than that of a solid blade disc, but the service life is also shorter. If you still choose a universal adhesive wheel for an angle grinder, then it can be used for processing and grinding various materials, which confirms the demand for these products.
Polishing and grinding tools may be of high quality, but they cannot guarantee successful completion of the job. What is the reason for this? It's very simple: the wood used must be thoroughly dried. Moreover, raw wood should not be used. Otherwise the result will be unpredictable. When choosing a blade for wood, you need to be sure that the material being processed has the appropriate properties.
Sometimes stripping work is required to remove the old layer of paint or varnish, or fungal infections. Polishing and grinding tools always perform at a decent level only if the wood is prepared according to technological requirements. Taking into account that polishing and grinding discs for grinders are not provided for initial processing, roughing attachments are required.
When choosing similar attachments for an angle grinder, you can feel the maximum benefit from them when cleaning old surfaces that have been painted many times. This is explained by the following factor: the nozzles are made in the form of a metal plate, which is densely studded with wire bristles located closer to the outer circumference, radially or perpendicular to the disk.
Tips for work
Finishing work begins only after the workpiece has been successfully given preliminary outlines. The results largely depend on what types of attachments are used to perform the assigned tasks.
Angle grinders are used as a cutter, as well as polishing and grinding devices. Attachments for an angle grinder increase the functionality of the device used.
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 type of consumables used. The characteristics of the tool determine the ability to process various workpieces, including natural wood. It is important to note that clearing complex wooden items, is carried out only using radial stripes.
- 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 processing of wood or other material, 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 wood processing devices perform specific tasks, but the grinding wheel sometimes surprises with its versatility and high level efficiency.
- A chain disk for wood is one of the most productive, but crude methods 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.
If it is necessary to carry out woodworking work, many people think about using an angle grinder as the main tool for work. Overall corner grinder can be used, but its scope is limited. Yes, with using an angle grinder You can sand, polish and strip wood. Nowadays, special attachments used when working with wood have become very popular, but not all of them can be used.
To understand whether it is possible process wood grinder, you need to study the structure and types of attachments that exist for it and what characteristics they have. So, any circle has its own diameter.
The most compact is 115 mm, which is often used for grinding and simple processing. The most common diameter is 125 mm, it is not heavy, and is used to grind and cut workpieces. Nozzles from 180 to 230 mm are used in high-power tools and are more often used in professional construction.
Types of discs are usually divided according to production technology and purpose (for metal, for stone).
Abrasive coated discs
Is universal disk- with his help Can cut and grind both metal and stone. Abrasive coating consists of corundum, electrocorundum or silicon carbide. The advantages of these circles include:
- Cooling of consumables due to the porous structure of the disk.
- It does not become dull during work.
- Wide range and low cost.
Disadvantages include:
- Formation of a large sheaf of sparks during work.
- Strong burnt smell when cutting workpieces.
- Fast wear.
The most common type of attachment for an angle grinder, which is used when working with stone and metal. There are three types of diamond blades:
- Solid. One-piece disc with continuous diamond edge. Designed for wet cutting of metal.
- Segmented, in which the cutting edge is divided into segments. Used for dry cutting.
- Turbodisk with cutting edge in the form of a wave, due to which the contact area with the workpiece is reduced, which ensures natural cooling of the wheel. Can be used for both wet and dry cutting.
The diamond blade is wear-resistant with very accurate cutting line, does not give off a burning smell, and the number of sparks during operation is minimal. Disadvantages include relatively high cost and poor heat resistance.
The use of diamond and abrasive discs when working with wood can cause the grinder to break, and replacing them with circles used in circular saws or milling cutters is prohibited - these attachments are designed for low speeds. The use of such wheels in an angle grinder can lead to damage to the tool itself, so it is becoming increasingly popular the new kind attachments: wood cutting disc for an angle grinder, the use of which is theoretically allowed in woodworking work.
Wood discs for angle grinders
Visually, they resemble a milling cutter; there are also discs with a chain surface. The most standard is a wood saw blade for an angle grinder with a diameter of 125 mm; as the diameter increases, the risk of injury during work increases. The optimal thickness is 2 mm, and the cutouts should be rounded towards the shaft. There are three types of wood cutting discs for grinders, which differ in the shape of the teeth:
- Trapezoidal suitable for cutting chipboard medium density.
- Variably beveled teeth are universal and are well suited for irregular work, when the type and thickness of the material is unknown in advance.
- Straight teeth are used for soft woods, such as conifers.
Sanding discs for wood
For roughing work, a flap disk is used, the working surface of which consists of several strips of sandpaper of various grain sizes. This attachment provides gentle sanding, however, you should remember that you need to work with well-dried wood.
In addition to the petal one, the so-called sticky disk. It is an attachment on which sanding paper of various grain sizes can be attached. The connection occurs using a special adhesive paste applied both to the circle and to the sandpaper. Using a Velcro disc, you can process both wood and metal and stone workpieces.
There are special attachments for brushing - the process of artificial aging of wood. They are brushes with metal, synthetic and sisal bristles, the choice of which depends on the stage of processing. Thus, a metal brush is suitable for initial roughing of the workpiece, synthetic bristles are intended for intermediate sanding, and a sisal brush is used for final polishing.
In conclusion, it should be noted that the grinder is not structurally intended for sawing wood and using carbide blades. For this there are special tools: circular saws, milling cutters. They have a lower rotation speed, and the use of wood cutting discs for an angle grinder systematically leads to injuries, including those incompatible with life. An angle grinder can be considered as a tool when working with wood only in the case of grinding work.
Angle Sander - universal device, with which you can work with any material. Perform cutting, grinding and grinding operations. It is popularly called the Bulgarian. When handling the tool, you need to carefully select the wheels. This depends on the size of the equipment, rotation speed and type of surface being processed.
Type of discs for grinders
The range of discs for angle grinders is large. When purchasing, you need to have a good understanding of what kind of grinder wheels there are. They differ depending on the work performed:
Characteristics and choice of circle
When choosing a circle for an angle grinder, you need to take into account what material you will be working with. In this regard, some factors are taken into account:
Sometimes you want to install a circular wheel on an angle grinder. This cannot be done. The reasons are as follows:
Wood cutting disc
The cutting disc for wood for an angle grinder is made of high-strength alloy. When choosing, you need to be guided the following rules:
- Hard wood requires the use of a wheel with an alternate bevel tooth.
- For coniferous and softwoods, a straight tooth is used.
- Medium-hard rocks can be cut with a trapezoidal tooth.
In progress the circles are warming up. It is not always possible to cool them. Therefore, slots are made from the side of the teeth to the axis. Their width is 2 mm and depth is 20 mm. Sometimes they are filled with copper. Compensation for expansion occurs. This prevents the metal from deforming.
Rough stages of work
At the first stage, the workpieces pass roughing. For this purpose, there are attachments for grinders for working with wood:
Gentle discs for wood
These are attachments universal type. They are used depending on the work performed:
Features of the tool cutter
The milling cutter as an attachment for an angle grinder is approved for use, but requires precautions. With its help, you can make grooves, roughly process the ends of the workpiece, or saw it. During operation, it cannot jam, but you need to know at what speed it can be used. It is important to consider in which direction the cutter rotates relative to the location of the angle grinder.
The surface quality will differ slightly from work on milling machine. However, the necessary operations can be done.
Using a chainsaw chain
If you wear chainsaw chain on disk, then you can saw boards up to 40 mm. You should be careful when doing this. To avoid injury, you must adhere to the following rules:
- Do not remove the protective cover. If it interferes with installation, then the equipment cannot be used.
- The speed is set in accordance with that indicated on the disk. Otherwise, the chain will jump off.
- Work is carried out in protective glasses and gloves.
If it is necessary to work with wood, it is possible to use attachments on an angle grinder for processing wood. However, you must first read the instructions. This type of work has its own characteristics. Without taking them into account, you can easily get injured.
A grinder or angle grinder allows you to process various materials, including wood. If there is a need to cut metal, resort to using an abrasive disc on a grinder. If you need to cut a brick or ceramic tiles, then diamond discs come to the rescue due to their high strength and durability. What to do if you need to saw or sand wood? To do this, you will need to purchase a special disc for a wood grinder.
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 - 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. When choosing a circle for an angle grinder on wood, it is important to pay attention to inner diameter shaft, which according to the standard is 22.2 mm.
It is important to know! Older 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.
Types of grinding wheels for wood
When choosing attachments for an angle grinder for wood processing, you should know that there are not only cutting discs, but also grinding discs. To sand wood using an angle grinder, a petal attachment is used. Working surface This consumable consists of several layers of sandpaper, which has varying degrees of roughness. The lower the roughness, the softer grinding can be carried out. Petal circles allow not only grinding, but also polishing work, which depends on the degree of grain size.
In addition to petal ones, there are also types of attachments that are very popular - these are sticky discs. They are known for their versatility, as they allow for quick replacement using a special Velcro. The cost of such consumables is much lower than that of the first option, but at the same time they have a shorter service life.
Grinding and polishing discs for an angle grinder must be of high quality, which affects not only the quality of the work performed, but also the safety of the master. The quality of wood processing is influenced by such factors as the degree of dryness. It is prohibited to process raw wood, as the result of such manipulations can be unpredictable.
If you need to carry out roughing work, which are often carried out as initial processing, then special peeling attachments are used. They are used primarily for the purpose of removing a layer of paint from a painted surface. Such nozzles are metal plates, inside of which there are metal wire bristles.
It is important to know! Grinding or polishing wood using an angle grinder is not difficult, but it is important to follow safety precautions.
Types of cutting wheels for wood
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 technological process provides for working with coniferous and soft wood.
- The trapezoidal tooth shape is suitable for cutting medium-density wood chips. Most often, such a tooth is universal and suitable for sawing hard wood.
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.(!)
It is important to know! When working with saws or cutting discs When working on wood for an angle grinder, you should be especially careful and careful. Without special need and experience, it is better not to carry out such work or replace it with other tools.
What you need to know when working with an angle grinder
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:
- 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 circles that have obvious signs damage.
- Resort to application individual funds protection.
Do not carry out work without using protective casing, with the exception of manipulations such as roughing, grinding and polishing wooden surfaces. It is especially dangerous to work with saw wheels. It is strictly forbidden to resort to installation on angle grinder discs from a circular saw or other tools. 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 significantly saves time.
An angle grinder, whose real name is an angle grinder, is a universal tool. They almost never do without it construction works. But in order for the tool to last a long time, it is necessary to select the right grinding discs. A disk for wood is fundamentally different from a disk for metal. What are its features, and what varieties are there?
Today, the entire range is divided into three main areas:
- Saw blades. They resemble a regular saw, but are made from completely different materials. Until recently, such specimens could not be found, but now they are sold completely freely. The most preferred option is tungsten carbide.
- Diamond coated disc. The most popular variety. In turn, it is divided into solid and segmented. Their scope is different, but there is common feature— high-quality and accurate results of work on concrete, metal or stone.
- Abrasive. Universal consumable, suitable for any type of surface. It cuts, grinds and polishes well.
Of the listed disks, the first and second are not suitable for wood. Natural wood has a very dense structure, and if you use a diamond disc, the grinder will overheat to the point of breaking.
The products also vary in diameter. The most practical ones have a diameter of 125 mm; in rare cases, a compact disk is needed - 115 mm. There are specimens up to 230 mm, but they are not suitable for wood. Their use may cause injury.
Selecting cutting wheels for wood
Cutting discs are divided according to three parameters - diameter, depth of cut and shape/frequency of teeth. Choosing the right option, there are a few things to consider: how often the product will be used and for what kind of wood.
Coniferous and other soft woods can be easily cut with a straight-toothed blade. If you plan to cut different wood, it is better to take a universal circle with variably beveled teeth. There are also trapezoidal teeth that are ideal for cutting through medium-density wood and solid wood.
Selecting grinding and polishing wheels
If cutting a material requires certain skills, then almost anyone can grind. Flap discs are usually used for this operation. Such a disk consists of several sandpaper petals arranged in a circle. Sandpaper provides a gentle sanding effect.
Another variant - abrasive disc Velcro. It is convenient to use, but even more convenient to change. Such circles do not last long, but also have a low cost. And, of course, they are many times more effective manual method processing with sandpaper. For example, using such a circle you can polish parquet.
Preparing the tree
Whatever the blade for the grinder, the work cannot be done efficiently if the wood is not properly prepared. Here are some tips on this matter:
- the wood must be thoroughly dried;
- special abrasive attachments are suitable for removing paint or varnish from the surface;
- the work is carried out in two stages, roughing and finishing.
Discs and other tools that will be needed for complete sanding or polishing of wood:
- Cord brushes designed for rough surface grinding. They help give the product an acceptable shape.
- The next step in processing a piece of natural wood is to use sanding attachment. If the subject is complex, you will also need to apply radial stripes.
- A felt circle made of pressed wool (coarse, fine or semi-coarse) will help get rid of the slightest roughness. With their help, the surface can be made almost mirror-like.
As you can see, when using various attachments, the grinder becomes a universal tool for woodworking.
Saws (chain wheels)
Suitable for cutting boards less than 4 cm thick. Use requires extreme caution. During non-working hours, the disc must be kept in a case, and during operation it must be used only at the speed indicated on the product itself.
Also, goggles and protective gloves are required when working. It is important to remember that under no circumstances should you use regular circles designed for a circular saw on an angle grinder.
Using an angle grinder for milling
A wood cutter for an angle grinder can be dangerous in unprofessional hands. For a specialist, its use is acceptable.
The milling cutter helps to level the edge, make grooves, cut workpieces and cut out bowls for log houses. Even on non-uniform wood, the tool will not jam or throw off. However, before starting use, it is important to carefully read the instructions and also observe the required speed.
The choice of cutters for angle grinders is quite wide, no less than for a manual milling machine. They are not intended for precision machining, but are quite suitable for shaping.
Safety rules during operation
In order for the use of a wood disc for an angle grinder to bring only benefits and not injury or damaged products, you must follow several important rules:
- choose the right circle according to size and properties;
- The operating mode of the machine must correspond to the requirements on the disk;
- Damaged wheels should not be used under any circumstances;
- protect your hands and face special devices and special clothing.
The attachment should fit effortlessly under the angle grinder casing. If you can’t do this, then do not remove the casing, it is dangerous.
Why can’t you use saw blades with an angle grinder?
The hardness of wood can vary even within a few centimeters. It may also contain clumps of resin and knots. All these uneven areas lead to the saw blade stopping abruptly, as a result of which the grinder is torn out of your hands.
