Disc for angle grinder for wood. Wood disc for an angle grinder: choosing the right tool. Sawing with a grinder
- What are they? cutting wheels?
- 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 are they? grinding discs and how are their characteristics determined? To fully answer the question, the entire market should be divided into main areas.
- Circles with abrasive coating. 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 best option disk for grinding machine made of tungsten carbide.
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 warping or destroying 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 laps 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 work 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 are empty, but in some cases they are filled with copper.
Equipment for grinding and roughing work
In most cases, working with materials requires not only polishing, but also 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, petal discs on an angle grinder are used for peeling. 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. His work 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, they are required roughing attachments.
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. The operation of the end disk 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 special attachments and discs are required to effectively process wood, metal and any other material of interest.
An angle grinder, whose real name is an angle grinder, is a universal tool. They almost never do without it construction work. But in order for the tool to last a long time, it is necessary to select the correct 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.
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 wood. medium density and woody areas.
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 option is 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 a 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 on an angle grinder you should never use ordinary circles intended for circular saw.
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 be thrown 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 injuries and 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.
If you are trying to understand whether it is possible to cut wood with an angle grinder, then the answer to this question is clear: it is possible. But many will not do this, because... Too many injuries people get from using an angle grinder as a wood saw, which is correctly called an angle grinder.
This is primarily caused by the fairly high speed of its rotation, at which most saw blades just not calculated. But who pays attention to this when the work needs to be done, and there seems to be a suitable tool at hand, and there is also a compensator ring for the saw blade for wood? the right size applied. And also protective cover They are removed for ease of work, which is strictly forbidden to do.
But we won’t talk about injuries, but we’ll talk about what and how you can process (including cut) wood during angle grinder help, but first - about the difficulties of working with an angle grinder specifically with wood.
Difficulties when working with an angle grinder
We mentioned the discrepancy between the speed of the grinder and the circular saw, but users who have an angle grinder with speed control can say that this factor was taken into account, and any saw blade for wood will be suitable for their tool.
Of course, by setting the number of revolutions of the grinder's output shaft corresponding to that indicated on the saw blade, they significantly reduce the risk of injury during operation, but do not eliminate it completely. This is primarily due to the material itself, or rather its structure and heterogeneity.
Even in different places of one trunk, a tree has different hardness, not to mention inclusions of viscous resin, the possible presence of metal found in the thickness of the wood: from pellets and bullets that hit the tree during a hunt, to wires that had grown into it, which were used to tie branches. Don't forget about knots, which are present in almost all types of wood.
When encountering the listed obstacles, the saw blade sharply slows down and, by inertia, the grinder is simply torn out of the hands, and when passing a hard section, it rushes forward with redoubled force.
When encountering metal, there is a high probability of chipping a carbide tooth, which can be captured next and thrown out at the speed of a bullet. It’s good if it’s within the range of the protective casing.
A person who decides to cut a tree is exposed to even greater danger, because in this case the grinder must be placed on its side, which changes the usual and comfortable grip, which means the grip weakens.
Grinder discs designed for cutting wood
1. Chain disks and cutters based on them.
Structurally, they are designed in such a way that even when biting the chain, which is similar in structure to saw chains for chainsaws, the base can rotate, so the tool will not be pulled out of your hands. These discs are primarily intended for external processing wood: cutting out cups in logs, removing bark, modeling, but you can also saw with them, especially with a 230-size disk, which costs a lot, but compensates for its cost with the safety of work.
2. Saw blades for wood with a small number of teeth.
To enlarge the picture, click on it.
Such discs indicate the maximum rotation speed and should be selected based on the parameters of your tool. Such a large pitch between the teeth compensates for the high speed of the grinder and makes sawing much safer than working with standard saw blades, but you should also be wary of metal in wood. You will see their work in the video:
In addition to wood, they can also handle plastic and aerated concrete.
3. Tungsten carbide discs.
This is a new product in the field of tools for angle grinders, allowing you to freely cut wood without fear of metal inclusions, operating at rotation speeds of up to 12,200 rpm. She is the only one that gives an absolutely positive answer to the question: is it possible to cut wood with an angle grinder? You can see this for yourself by watching a short video about the operation of this disk:
Needless to say, these blades cut more than just wood.
4. Another tool, to one degree or another, suitable for cutting or other processing of wood using a grinder.
First things first:
a) Rotarex produces discs for cutting wood. In terms of their performance, primarily safety, they are inferior to those listed above, but are clearly more suitable for sawing wood than circular saw blades;
b) wood cutters designed for external processing of wood with angle grinders can also cut thin wood;
c) plane disk – attachment for an angle grinder.
d) saw to create wooden sculptures with a configuration of cutting elements vaguely resembling links saw chain, is not entirely intended for sawing, but will cope with it to some extent.
Grinder for sanding wood
But this work, incl. on wood, specifically for this tool. Just a small photo selection of angle grinder attachments for grinding is evidence of this.
- for rough grinding.
- The most common type of attachments for grinding angle grinders, cleanliness depends on the size of the abrasive grain on the blades.
- the simplest option for changing grinding wheels using a holder attachment with a sticky base on which replacement ones are attached abrasive wheels with different grains or even polishing bristles.
- polymer abrasive nozzle made of silicon carbide with nylon.
- belt attachment for sanding.
And instead of a conclusion. Is it possible to cut wood with a grinder? It depends on what and what. If you cut a thin dry twig, then there are practically no restrictions, but if you have to do more serious work, see above.
Dear readers, if you have any questions, please ask them using the form below. We will be glad to communicate with you;)
The modern grinder is often used to perform various works in the process of renovation and construction. Such a tool can be called universal. The grinder easily cuts almost any object, grinds, sharpens, polishes and peels. To perform work using a grinder, it is necessary to select the right discs, taking into account the type of tool.
Grinder wheels for wood
An angle grinder (grinder) performs a wide range of different operations using rotational movements of replaceable discs or attachments. The most commonly used circles are metal, stone, and wood. All of them are divided into three main groups:
- Cut-off
- Grinding (cleaning)
- Grinding (grinding)
Each group has its own types of discs, which are designed for a specific type of work, including wood.
Woodworking discs look like a regular circular saw; you need to know how to work with them, since careless movements or inattention can lead to serious injuries. The protective casing on the disk serves as good protection, so it is better not to remove it from the tool and, for your own safety, use a wheel with fine teeth. According to experts, it is best to work with wood attachments without strong feed and try to permanently secure the angle grinder using a special device for this.
The most common ones can be called wood circles - cutters, they look like metal circles with teeth and are specially designed for cutting wood. The circles can be different in size; depending on the thickness of the timber, the diameter of the cutter is selected.
For cutting wood, only saw blades and right choice provides a wide range of possibilities. If you know how to use the tool, you can even cut at an angle.
Disc production
Saw blades for grinders on wood come in two types - monolithic and with carbide tips at the ends of the teeth. If there are such soldering on a saw blade, then they wear out less quickly, do not require wiring, and perform better cuts, but they need to be sharpened only on special machines.
For the production of saw blades, only carbide sheet steel. She guarantees the product high stability to mechanical damage and temperature changes. During the production process of the saw wheel, much attention is paid to the weld; it connects the body of the disc with the teeth, so its quality is always under control.
The speed and frequency of cutting is influenced by the number of teeth on the wheel; the higher the frequency of the teeth, the better the quality of wood cutting, but at the same time the speed of work decreases. When there are fewer teeth on the cutter, the speed increases, but the cleanliness of the cut deteriorates.
Impact of disc teeth
The final result of working with wood depends not only on the frequency of the teeth, but also on their shape. Universal saw blades can be called variable tooth cutters, they work well on hard and soft woods. Products with trapezoidal teeth are only suitable for working with soft materials. For draft Wheels with straight teeth are suitable.
During processing valuable species For wood, you need to use thin saw blades; they are great for cutting or processing expensive wood. There are also “thin +” discs, which use a material with an additional bumper; it reduces the blocking of the saw during its operation. This saw blade is suitable for longitudinal and cross cutting of wood, as well as other materials. Similar materials with high cutting precision are also used in furniture and wood processing production.
Features when working with saw blades
When working with a saw blade on wood, you need to exercise special care and skill, best wear a special uniform and safety glasses and gloves. The difficulty of working with wood lies in the fact that wood is easier to cut, so it is necessary to maintain control in the operation of the tool. Experts recommend using tools of low power and speed when working with wood, the most best option- 1,000 rpm.
The quality of the grinder and the cutter are no less important; the final result of the work and its safety will depend on this. It is best to give preference to a proven tool and hear the opinion of experts to be sure of a positive result.
Grinding wheels
To perform various works made using a grinder grinding and polishing wheels, they can be:
- Spongy
- Felt
- With replaceable sandpaper
- Fabric
The material is selected depending on the surface that is planned to be sanded. Petal blades are used for processing wood species. grinding wheels, they are made of sandpaper, which is fixed to a rigid frame. Sandpaper can be coarse or fine grain; the markings can be seen on the product itself.
If planned make wood smooth, then it is best to use a fine-grained wheel to remove a small layer of wood - medium-grained. If you need to delete old paint, then you need to use a coarse wheel.
By design, grinding wheels can be flap, movable and hard. Petal wheels give the smoothest surface to wood, so they are used as finishing wheels.
Conclusion
When working with an angle grinder, you should always follow safety precautions. It is good when the tool is equipped with a stop handle and a protective casing. Devices that have a chainsaw chain at the edge are considered safe; it is specially installed there. If one of the teeth jams, the disk rotates idle, and this reduces the risk of injury.
The angle grinder is very useful tool, which can be used in various areas of production. It is thanks to its versatility that it has become widespread both in industrial facilities, and at the household level.
Types of attachments for wood
Only angle grinders with speed control are suitable as a tool for wood carving. Since the main purpose of the grinder is grinding homogeneous materials, it is suitable for processing non-uniform structures wooden materials must be approached very carefully.
The following types of wood circles can be distinguished:
- Wood saw for grinder
- Cutting discs
- Planers
- Grinding
Each of these parts must be used for its intended purpose.
Saw blades
A saw blade for wood for an angle grinder consists of a metal circle with a chain attached to the edge. Design of special sawing tools similar to those used in chainsaws. But they are made saw wheels made of tungsten carbide. When a grinder blade for wood hits a solid obstacle in the wood - knots, resin, metal, its base rotates without destroying the chain. Chain attachments You can quite simply strip the logs of knots and bark and give them the required original shape.
Cutting discs
Various manufacturers also produce cutting wheels for wood specifically for angle grinders, for example, the Bosch cutting wheel. Their design differs significantly from the design of circular saw blades. They usually have side teeth that protect the nozzle from jamming. Vary cutting tools by number and shape of teeth:
- beveled;
- straight;
- in the shape of a trapezoid.
The first option for the tooth shape is considered universal. It is suitable for any type of wood for small amounts of work. When sawing 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. Minimum size– 115x22 mm. The most commonly used circles are 125 mm in diameter; they are universal and suitable for a wide range of work. The maximum possible size is 230 mm. But it is undesirable to use the latter option when working with wood, as the likelihood of injury increases. Depending on the selected size, the depth of the wood cut will also be different.
Discs - planes for grinders
Maybe using an angle grinder as a plane. For this purpose, special circles are used - planes. Working with such attachments is allowed without a protective casing, since solid discs are not destroyed. Many brands of wheels can be sharpened many times. Before using the grinder, you need to install an additional handle to more securely hold the tool with both hands.
Sanding discs
This type of circle allows you to use the machine for its intended purpose. For finishing and polishing wooden surfaces can be used various types nozzles:
- cord brushes;
- end circles;
- petal nozzles;
- sanding wheels;
- stripping attachments.
Rough processing of wood is carried out using special cord brushes. End discs are designed to align the edges of parts, which is often required when making bevel cuts on workpieces. They are an excellent substitute for a file.
Widest range grinding attachments– y petal circles. 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 special nozzle allows you to sand quite large areas wooden surfaces. The ability to quickly change the sanding coating makes these attachments universal.
When deleting old paint coatings Peeling 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.
Universal wood cutting discs for grinder Graff Speedcutter
Wood disc for grinder Graff Speedcutter- This circular saw with three teeth, which is intended for high-speed angle grinders. It is used in models with maximum speed rotation 12.2 thousand revolutions per minute.
The three carbide teeth are made of tungsten carbide and are positioned at an angle of 5° to the tool base made of steel. Thanks to this design and the special shape of each tooth, the cutting surface is very clean and smooth. A disc for the Graff Speedcutter grinder is being manufactured, measuring 125x22.23x3 mm. The cutting width of the wood is 3.8 mm.
Graff Speedcutter wheels are designed for artistic wood carving, deburring and sanding. various breeds tree. They are also used for cutting and selecting grooves in wood, its transverse cutting and longitudinal cutting. It is possible to use such attachments when processing parts made of aerated concrete and aerated silicate, fiberboard, chipboard, laminate, and plasterboard.
Rules for working with the tool
Any tool can pose a serious danger if the instructions for use in a specific situation are not followed. A grinder for cutting wood is no exception in this sense. The main points that are necessary when working with grinder discs – angle grinders for wood:
- Choosing the right circle size
- Installing a wood disc for an angle grinder
- Selecting the appropriate operating mode for the machine
- Avoid using damaged circles
- Use of personal protective equipment
The size of the nozzle should be installed under the protective cover of the machine without any problems. If this does not work, do not remove the protection. When working on wood with an angle grinder, you must use only special wood wheels for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or damage to the tool. To avoid destruction of the wood disc for an angle grinder, rpm grinder must correspond to those indicated on the surface of the circle. Before starting work, you should check the wood disc for defects and damage. If they are present, then it becomes dangerous to use. When working with the tool, it is necessary to wear eye and hand protection. It is best to use thick overalls.
