Wheels for grinders what are the diameters. How to choose a wheel for a grinder: grinding, polishing, roller cutter, roughing, abrasive

(Bulgarian) refers to a tool with which they perform diverse work: they cut, clean, grind, polish, brush. To do this, use discs for a grinder and different types of attachments. The main thing is to make the right choice of consumables. The attachment must correspond to the operation to be performed on a specific grinder model. They are produced in a large assortment, each type is used to solve a specific problem or several operations. You can buy them in the retail network from Russian and foreign manufacturers at different prices. Consider the main types of nozzles, their purpose and selection features.

Grinder wheels are replaceable elements. When working with different materials, you need to understand their types. This will help to perform the required operation. Circles are classified according to the following parameters:

• by appointment;
• type of work performed;
• constructive performance;
• type of cutting;
• material of manufacture;
• sizes.

According to the purpose, there are nozzles for performing work on metal, wood, stone, concrete, marble, etc. Manufacturers indicate the purpose in the marking, which is applied directly to the product itself. Many varieties are versatile tools suitable for processing several types of materials.

By the type of work performed, which is indicated in the name, manufacturers produce the following attachments for angle grinders:

• cleaning (metal brushes, with a mandrel, batch);
• roughing (grinding wheels, twisted cutters, rough diamond);
• sawing. The presence of teeth on the cutting edge is a design feature of the product. This allows you to get a high-purity cut on wood, plasterboard, gas silicate, plywood and other similar materials;
• detachable. Cutting and diamond discs are produced with a solid cutting edge and divided into segments;
• grinding (discs with varying degrees of grain and hardness);
• polishing (felt, felt, with a special Velcro and grinding);
• for cutting seams in asphalt, concrete, etc .;
• milling (for cutting grooves, bowls, edging, etc.);
• sharpening. A characteristic feature is the ability to perform operations with a lateral surface.

The disc is a product of a certain diameter and thickness, having a bore for attachment to a grinder with a cutting edge of a solid, segmented or shaped configuration. The choice of a specific type depends on the operation being performed and the material on which it will be carried out. Cutting with these attachments can be done dry, wet or in combination. The marking indicates this feature.

Discs by material of manufacture are abrasive, carbide, diamond and brush. The basis of the wheels of the first type is a special latex paper or fiber, on which an abrasive layer with a binder is applied. Made of fiber, it comes with a rubber or plastic backing pad. Carbide wheel is a product made of alloy steel. These consumables can be used for cutting aluminum, stainless, high carbon steel and other materials, which is indicated in the marking.

Diamond discs are a universal consumable. It is a steel product, the surface of which is diamond-coated. This allows for the finest cut in any material. Popular products, popularly called turtles, are a type of nozzle made on a flexible basis, have a corrugated structure and are attached with Velcro. In addition, they produce diamond blades with a solid edge for wet cutting, segment and turbo segment for dry cutting and combined.

Standard disc sizes

The dimensions of the grinders are standardized. The table shows the main technical characteristics of attachments for grinders:

The sizes of non-standardized wheels may differ from those indicated in the table if they are made according to the manufacturer's specifications.

Cutting discs

Cut-off, or they are also called abrasive, discs for grinders are used most often. Electrocorundum or silicon carbide of various sizes and hardness is used as abrasive grains. Nozzles are produced on bakelite (with and without reinforcing elements) and vulcanite bundle flat and with a recessed center. The latter type cuts on metal with an emulsion, since it has a low degree of heat resistance and cannot work under increased loads. Discs differ according to the material with which they can work. There is an inscription and color in the marking of such products. Decoding of inscriptions in the table:

If there is a blue stripe on the disc, then the circle is intended for working with metal, green - with concrete.

The circle markings are clearly shown in the figure.

Products on a vulcanite bond operate at a speed of 50 to 80 m / sec, on a bakelite bond - from 80 to 100 m / sec.

The disc itself indicates the date until which it can be used, that is, the expiration date. If it is on a vulcanite bond, then this period does not exceed 1 year, on a bakelite bond - 6 months.

The degree of surface cleaning depends on the grain size. A distinctive feature of the grinding wheels is that they have the same bore diameter, equal to 22 mm. They are available with outer diameters of 115, 125, 150, 180 and 230 mm and thicknesses from 3 to 20 mm.

This group of products includes cord brushes, the working surface of which is a metal wire. Products are called twisted cones and are cup-shaped and disc-shaped.

Grinding discs

Products of this group allow you to grind with the required degree of roughness on metal and wood. The size of the grain plays an important role. The finer the grain size, the higher the quality of the sanding surface. Manufacturers produce wheels with the following grain size: 50, 100, 200, 400, 600, 800, 1000, 1500, 2000, 3000. Consumables can be made of emery, have a spongy, felt, felt or fabric surface.

The felt wheel is used to perform the polishing operation on grinders, which are equipped with a speed control device. Products are made from coarse or fine wool of sheep, cows, goats, camels. The diameter of such circles is from 50 to 150 mm, and they are 25 or 30 mm thick. It is recommended to polish at the speed specified by the manufacturer of the consumable.

With the help of sharpening discs, the edges of the cutting tools are brought into working condition, and welded seams are also cleaned. Available flat and bowl. A distinctive characteristic of such products is their thickness, it is not less than 5 mm.

How to choose the right disc for a grinder

Wheels for grinders in the retail network can be bought in a varied assortment and at low and high prices. Various operations are performed using products made of different materials and using different technologies. What are the basic rules for choosing and what to look for? It is necessary to clearly know what materials to work with. And you also need to pay attention to such factors:

• diameter and thickness (indicators should not be more than indicated in the passport data for the grinder, or, more simply, the disc should fit into a protective casing);
• landing size (must correspond to the diameter of the grinder's spindle);
• rotation speed (it must correspond to the type of grinder, it is indicated on the disc itself);
• type of cutting (dry, wet or combined).

The rules that must be followed to make the products last longer are simple. For hard materials, discs with a soft binding are chosen, for soft materials - with a hard one. The working area during operations should not overheat. Therefore, it is recommended to periodically remove the disc from the material to cool it down. You cannot make a deep cut in one pass. Do not press the product with great force and work at high speeds. Remember: if in the process of work there is a beating of the disc, cracks appear on it, such a consumable cannot be cut. It needs to be replaced.

The video tells in detail and clearly about the discs for the grinder:

An angle grinder (angle grinder), commonly referred to as a "grinder", is widely used at construction sites and in everyday life during repairs. It can be used to carry out many different technological processes. In order to choose the right tool for performing a certain type of work, you need to familiarize yourself with what kind of discs and nozzles for angle grinders are. The tool for this device is selected by size and function.

When choosing a disc for a grinder, you must make sure that the outer diameter of the attachment does not exceed the maximum allowable values ​​allowed for your angle grinder. For example, if a grinder is designed to use a circle with a maximum diameter of 125 mm, then a 230 mm circle cannot be installed on it. And there are several explanations for this:

• the linear speed of the cutting edge will be exceeded, which is fraught with destruction of the abrasive wheel and injury to the user;
• a small grinder does not have enough power to work with a large tool;
• the installation of a nozzle that exceeds the permissible dimensions requires the removal of the protective casing, and this is already a violation of safety rules.

Discs for angle grinders have standard sizes: 115, 125, 150, 180 and 230 mm. In modern grinders landing diameter(the diameter of the shaft on which the tool is installed) is practically the same and equals 22.2 mm. If you have an outdated grinder "lying around", then you will need to use adapters - rings of different diameters.

All abrasive wheels of all sizes have special marking, from which you can find out the following information: the diameter of the disc and its thickness, the diameter of the seat, the maximum rotation speed, and what materials it is intended for processing.

Purpose of discs and attachments

Grinder wheels differ in purpose for:

• detachable;
• stripping
• grinding;
• sharpening.

Cutting discs

The most common task performed with a grinder is cutting various materials. The choice of tool material also depends on what material needs to be cut.

1. Metal cutting... The metal cutting disc is made from crystalline alumina corundum, as well as from a synthetic corundum called fused alumina. The main color of wheels for cutting metals is blue.
   
   
2. Cutting stone and concrete. For cutting stone, you should choose a disc made of another abrasive material - silicon carbide. This abrasive easily cuts white brick (silicate) and slate. But to cut red brick, some types of concrete or ceramic tiles, this circle material will not work. Stone discs are available in green.
   
   
3. Cutting ceramic tiles, red brick, porcelain stoneware and concrete... For these purposes, a diamond disc is already being used.
   
   
   This nozzle is made of metal, an abrasive mass with diamond chips is applied to the cutting edge. The illustration above shows a segmented saw blade designed for dry cutting of material. All-metal discs require water cooling during operation.

   

4. Wood cutting. Although there are saw blades on the market that are no different from circular saw blades, it is best not to use them for safety reasons. When working with such a tool, the user is often seriously injured due to jamming, bouncing, accidental slipping of the tool, etc.
   

Therefore, if you are still going to use a saw blade for wood, then you should adhere to safety measures. A protective cover and a handle must be installed on the grinder, the user must wear a protective mask or goggles. In addition, you must not use this tool to cut materials that are not intended for it.

The safest are discs for wood, along the end of which a chain from a chainsaw is installed. If the tool becomes jammed, the chain stays in place and the disc rotates idle, reducing the likelihood of injury to the user.

Roughing

If it is required to remove a layer of paint or other application, as well as rust from any surface, apply corsets... They are disc-shaped or in the form of a bowl with built-in metal wire.

The wire in these attachments can be twisted or loose. Its thickness can also be different. The thicker the wire, the more roughly the roughing disc or bowl is used, and vice versa.

Grinding

Grinding discs and attachments are used for grinding and polishing various surfaces (metal, wood, plastic and others). Often a grinding wheel is used for grinding. petal type... It consists of many "petals" made of sandpaper. The grit size of the sanding paper can be selected based on the required type of processing (finishing or roughing).,

Also sandpaper can be attached to the nozzle with Velcro... Such a tool is screwed onto the spindle of the angle grinder.

For surface polishing, special wheels and attachments are produced that look like felt pillows or fabric discs.

Sharpening

To sharpen the tool, grinding machines (sharpeners) are usually used. But if you do not have the latter, but you have a grinder, then you can purchase a sharpening (grinding) wheel for it, with which you can easily sharpen almost any cutting tool.

The main difference between sharpening wheels and cut-off wheels is their thickness (at least 5 mm).

How to properly change the disc on the grinder

Since the circles for the grinder are consumables, sooner or later they have to be changed. They are attached to the spindle of the angle grinder using a clamping flange (nut) with an M14 thread. To unscrew it, the grinder must be equipped with a special open-end wrench having pins on one side.

So, to replace the tool on the grinder, follow these steps.

1. De-energize the device by pulling out the plug from the socket.
2. Lock the spindle of the angle grinder using the button located on the front of the case. When the button is pressed, the stopper enters the hole of the disk installed in the gearbox, which fixes the spindle in a fixed position.
   
   
3. Insert the pins of the key into the holes on the hold-down flange.
   
   
4. While holding the latch with one hand, turn the wrench to the left (counterclockwise) with the other hand until the nut comes loose. Then it can be unscrewed without a key and removed from the shaft.
   
   
   In this case, the angle grinder spindle rotates clockwise. But in which direction to unscrew the nut if your apparatus rotates the shaft counterclockwise? Remember: the clamping flange should always be unscrewed in the direction opposite to the rotation of the shaft.
5. Now you can change the tool, having previously removed the old one.
   
   
   If you notice that dirt has accumulated inside the casing, then you should remove the lower flange and use a steel brush to remove dirt from all surfaces.

   

6. Next, you should install the bottom flange in place. You need to put it correctly, be sure to align the grooves on the spindle and flange.
7. Lay on top of the bottom flange gasket. It is not necessary to install it, but it is desirable, since it will provide easy unscrewing of the clamping nut in the future, if you need to change the tool.
   
   
8. Install a new tool. Sometimes the owners of angle grinders ask themselves the question: which side to put the circle on? The answer is simple: place the disc with the marked side out.
9. Place a pad on the abrasive wheel. If gaskets did not come with your grinder, then they can be purchased in a specialized store, or on your own cut from thin sheet metal or cardboard.
   
   

   

10. Screw the flange onto the shaft by hand. Tighten the nut until you can no longer turn it without a key. After that, holding the stopper, tighten this nut with a wrench, but no more than a quarter of a turn, otherwise the disc will begin to deform.
    
    

After performing the above steps, the tool change is considered complete.

Spinning methods if the disc is jammed

What to do if the hold-down flange is stuck? This nuisance, when the nut is bitten, often occurs if, while working with thick and durable materials, the tool is jammed in the workpiece. In this case, the abrasive wheel often breaks, and the spindle continuing to rotate tightly tightens the clamping flange. There are several ways to spin the grinder if the disc is jammed.

With a gas wrench

This method is considered not entirely safe, since it is possible to break the stopper, although in most cases, it is possible to unscrew the nut. To avoid breaking the spindle lock, do not apply too much force to the gas wrench. The retainer is designed to withstand the force of a standard wrench.

An overly tightened flange can be unscrewed using 2 gas keys. To do this, break off the protruding ends of the abrasive wheel with pliers so that you can reach the bottom flange with the first gas wrench. Next, tighten both flanges with wrenches and turn them in opposite directions (taking into account which thread on the spindle is right or left).

Disassembly of the gearbox

In the event that the retainer is broken, you will have to disassemble the gearbox to remove the tool from the angle grinder... Use pliers to break off the edges of the remaining abrasive wheel so that you can get to the bolts holding the gear cover. After that, unscrew the fasteners and open the gearbox. The cover will be removed together with the pinion shaft. Further, this shaft should be clamped in a vice, having previously laid aluminum gaskets between the steel jaws, and unscrew the flange using a gas wrench (do not forget to determine the direction of unscrewing).

Heating nut

The nut can be heated with a gas torch, hot air gun or blowtorch. The heated flange can usually be unscrewed with a standard grinder wrench.

Sewing off a jammed circle

If, after applying the first 3 methods, the nut does not loosen, then the remaining abrasive disc between the flanges can be ground off. To do this, follow these steps.

1. Use pliers to remove the rest of the circle around the edges of the nut as much as possible.
2. Clamp a piece of sheet metal as thick as the disc itself in a vise, turn on the grinder and grind off the rest of the circle on the end of the sheet metal.

Instead of iron, you can clamp a piece of an abrasive wheel in a vice. In this case, the grinding of the rest of the tool between the flanges will occur faster, and the nut can be unscrewed by hand.

But the use of a stationary abrasive wheel requires great care, because when grinding off the remnants of the tool, the geometry of the flange can be damaged. If this happens, you will have to trim the nut.

Using a penetrating lubricant

Water the flange-to-shaft connection abundantly. liquid WD-40. It tends to penetrate into inter-threaded spaces and small cracks. After applying the liquid, wait about 5 minutes and try to unscrew the fasteners with a standard wrench.

Using a puncher

Some owners of grinders, in a situation where the clamping nut is jammed, install a nozzle in the hammer drill “ chisel "or" jackhammer”, Insert it into the hole of the flange at an angle and turn on the mode of a jackhammer without rotation. Accordingly, the stop button must be pressed. Just a couple of gentle clicks with a hammer drill are enough (so as not to break the shaft retainer), and the nut will begin to turn.

Cut the pressure flange with a hacksaw

This method can be called radical, since you will have to buy new fasteners, and it is used if the nut is not unscrewed by any other methods. To cut the flange, hold down the stopper button so that the shaft does not rotate, and using hacksaw for metal, cut the retaining nut.

A real owner must have a grinder for household needs and at work. But without the right circles, it is not always possible to achieve the desired result. Therefore, special attention is paid to their selection.

What is a grinder and what is it for?

The original purpose of the tool was only for cutting the inner corners of large and hard-to-reach parts. Hence the name - an angle grinder or angle grinder. But later the scope of application expanded, and today the main purpose of the grinder has become cutting metal and stone.

Disc sizes

Not only grinders are different, but also their circles. The first thing that catches your eye is the difference in the diameter of the parts. For this parameter, disks are:

But the most common diameters are 125 and 230 mm.

The smallest size a disk can have. It is rarely purchased. However, if it is necessary to perform specific work, sometimes you cannot do without it.

The diameter is optimal for housework that is required from time to time. It is a small and very handy tool that can be operated with one hand.

150 and 180

Although the sizes of the circles are not as popular as others, they are sometimes chosen. For example, when constant work is required around the house, for example, when carrying out repairs, then a diameter of 125 mm will clearly not be enough. The instruments are considered semi-professional.

This disc is purchased when you need to work in a constant mode with thick material. The nozzle is distinguished by its high performance, and therefore it is precisely it that is chosen for professional purposes.

Types of disks by functionality

With a grinder, you can perform different types of work. For this, special discs are purchased. Certain types include:

for cutting hard materials;

for grinding of various degrees (you can perform both rough sanding and mirror polishing);

for roughing off rust and paintwork.

Types of cutting discs

The most popular are cutting discs. Thanks to them, it is possible to cut any hard material, such as metal, concrete or stone. In some cases, this tool is irreplaceable.

Wood discs are considered traumatic. Therefore, in some cases it is better to find more suitable tools for processing. But diameters 115 mm and 125 mm are acceptable for this purpose.

Abrasive discs

They mainly use abrasive discs for cutting metal and stone. Previously, they were fragile, and therefore dangerous to use. But today such circles have a multi-layer structure, due to which the use has become harmless. The abrasive is located between the layers. It scrapes off a thin layer of the material being processed. Thus, the cutting line is polished.

Diamond discs

The difference between these types lies in the application of diamond chips to the outer radius. To avoid distortions during heating, there are also special expansion grooves that make the cut easier.

Types of grinding discs

Grinding wheels are flap and abrasive. Both are equally effective. But when working with an abrasive look, such irregularities in the surface of the material, such as residues from welding, burrs from metal, and others, are also removed. The petal discs function more smoothly. Solid elements can also be removed, but the embossed surface will generally be better processed.

Other types of discs

There are other types of attachments. Recently, Velcro attachments have become very popular. They are acquired when it is necessary to perform frequent grinding of metal.

Other interesting attachments are the brushes, which are successfully used for grouting and cleaning various surfaces. It is often a good alternative to an abrasive grinding wheel.

How do I install the disc correctly?

To work with angle grinders, it is imperative to comply with all safety requirements. These include the following.

Change the circle only when the device is off.

When cutting, the tool must be equipped with a protective cover.

The work is done with glasses and mittens.

The grinding disc is used exclusively for grinding and the cut-off disc is used for cutting.

There should be no fuel in the direction of the sparks.

1. What are cut-off wheels?
2. Tips for work

The angle grinder, popularly known as the Bulgarian, is a worthy and versatile tool. It is this equipment that allows you to successfully perform cutting, grinding, polishing, sawing off 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 of discs and a specific approach, otherwise the work will not bring the desired results.

Grinder wheels: starting with market research

The assortment is striking in its variety. What are sanding discs and how are their characteristics determined? To fully answer the question, the entire market should be divided into main areas.

1. Wheels with abrasive coating. This consumable tool is universal, therefore, with its help, any workpiece can be cut and polished with high quality. In addition, the possibility of polishing is assumed. Abrasive tools are considered one of the best for a reason.
2. A diamond-coated grinder disc is one of the most common construction tools. These products are segmented and solid, and for each option, its own area of ​​use is determined. In each case, it is assumed the possibility of high-quality and accurate cutting of durable materials, including stone, metal, concrete monolith.
3. Saw blades for a grinder visually resemble modern saw models. However, other alloys are used for their production. Previously, the production was rare, but now its prevalence is growing rapidly. The best tungsten carbide grinder disc option.

Taking into account the variety of modern products, one should abandon the senseless and sometimes dangerous attempts to install a circle from a circular to a grinder. Any circular discs are designed for low speed, and there is a risk of warping or destruction of the tool on the grinder.

How to choose the right angle grinder model?

Studying modern circles for a grinder, it is important to understand the basic principles of choosing a consumable for angle grinders. What aspects to take into account?

Grinding wheels are available in several standard diameters. The smallest model is 115 mm. However, discs for a 125 mm grinder are of greater practical importance. Moreover, it was the angle grinder for the 125th circles that received the widest distribution 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 circles. Grinder discs, which are designed for cutting metal or concrete, are categorically 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 the standard installed shaft diameter is 22.2 mm. There used to be several divisions, so labeling still plays an important role. Today, for example, a standard saw blade for woodworking has a diameter of 125x22.2 mm.

Although the maximum angle grinder size is 230 mm, such dimensions are undesirable when processing wood. Choosing a tool with a large diameter (from 150 mm), you run the risk of serious injury. Preferred dimensions are 115x22.2-125x22.2 mm. In addition, the 125th circles are able to cope 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 a grinder, for safe and effective processing of natural wood.

What are cut-off wheels?

Parameters used to classify cutting discs by wood:

• Disc diameter;
• Cutting depth of a tree;
• Characteristics of the teeth: shape, frequency, number.

What to consider when planning to use a cutting disc for a modern grinder?

1. If sawing discs for a grinder for wood are rarely used, and the type of wood to be processed will be different, it is best to choose a model with variable beveled teeth.
2. For cutting softwood and softwood, models with straight teeth are suitable. These saw blades successfully cut even the softest woods, ensuring a decent work result.
3. The trapezoidal tooth can be used universally. Choosing such equipment, it is best to cut the medium-sized particle board. Other types of products can be used if desired.

What parameters should you take into account for successful woodworking when choosing consumable sawing tools?

1. Rounded cutouts are required to be made towards the shaft.
2. The optimum disc thickness is 2 mm.
3. The depth of the cutouts can be up to 20 mm.
4. The cutouts are 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 dangerous... At the same time, any person with the necessary equipment can grind the array. The most important thing is to understand the principles of performing technological operations.

Most often, flap discs on a grinder are used for peeling. Having carefully studied the specifics of the product, it is possible to understand how functional and effective it is.

The name gives an initial idea of ​​the features of the device of the consumable tool. Its work surface has several sandpaper petals. This structure is comparable to fish scales. At the same time, such paper with a low roughness ensures a soft sanding of natural wood. The quality and degree of processing depends on the grain size of the material, therefore polishing and grinding can be performed in accordance with the requirements.

The flap disc for the grinder is quite popular, but if you wish, you can use another consumable tool.

For example, the sticky universal disk deserves attention. Modern attachments for the grinder provide the ability to quickly change the Velcro. The price of the sticky discs used for basic operations is lower than that of a solid paddle disc, but the service life is also shorter. If, nevertheless, a universal sticky wheel for the grinder is chosen, then it can be used for processing and grinding various materials, which confirms the demand for these products.

The polishing and grinding tool may be of good quality, but it 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 cannot be used. Otherwise, the result will be unpredictable. When choosing a disc for wood, you need to be sure that the material being processed has the right properties.

Sometimes it is required to carry out stripping work to remove the old layer,. Polishing and grinding tools always show themselves at a decent level only if the wood is prepared according to technological requirements. Whereas grinder polishing and grinding discs are not provided for initial processing, roughing attachments are required.

Choosing such attachments for the grinder, you will be able to feel the maximum benefit from them when cleaning old surfaces that have been repeatedly painted. This is due to the following factor: nozzles are made in the form of a metal plate, which is densely covered with bristles made of wire 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 pre-shaped. The results largely depend on what types of attachments are used when performing the tasks.

Angle grinders are used in the form of a cutter, as well as polishing and grinding devices. Grinder attachments increase the functionality of the device used.

So how do you carry out the polishing and sanding process when working on wood? What tools do you need to be successful?

1. Brush cord. These tools are ideal for rough sanding wood. The possibility of a successful leveling of the wood is assumed, with the addition of an optimal shape to the product.
2. Face discs make it easy to grind workpieces. In most cases, such work is required for bevel cuts. The face disc works like a workpiece with a saw.
3. Flap sanding attachments are the most demanded option for the used consumables. The characteristic of the tool determines the ability to process various workpieces, including natural wood. It is important to note that the cleaning of complex wooden objects is carried out only using radial strips.
4. Felt circle - allows you to achieve minimum roughness of the processed products. The basis is compressed wool, fine-haired, semi-coarse and coarse-haired. The felt working tool allows not only to carry out high-quality processing of wood or other material, but also to give a perfectly smooth surface, comparable to a mirror.
5. The grinder wheel designed for grinding is often compared to the disc of the same name. It is important to note that the Velcro circle is a versatile tool with a wide range of applications. Various woodworking attachments perform specific tasks, but the grinding wheel sometimes surprises with its versatility and high level of efficiency.
6. The wood chain disk is one of the most productive, but rough ways 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 work. Marking discs, wheels and grinder attachments is a guarantee of a successful result.

A modern grinder is a convenient and effective tool. For high-quality work, special attachments and discs are required, which make it possible to efficiently process wood, metal and any other material of interest.
