Bulgarians grinding on wood. Choosing a wood disc for a grinder, grinding angle grinder. Grinding disk for wood for a grinder: characteristics

Bulgarian, or angle grinder (angle grinder), is a very popular instrument which is versatile. It is used in the execution of most construction works. Many people are interested in the question of whether it is possible to cut a tree with it. To process this material, it is necessary to choose the right wood disc for the grinder. There are many varieties of nozzles, differing in characteristics and purpose.

The range of nozzles for this tool is quite wide. Products are classified according to their purpose, depending on which 3 main groups of circles for angle grinders can be distinguished:

saw;
With diamond-coated;
abrasive.

Saw. They are similar to standard saws, but are made from other materials. The most common option is tungsten carbide discs. They are not suitable for woodworking.

Diamond coated. This group of circles for the grinder is the most extensive. The high popularity of diamond-coated nozzles is due to a wide operational spectrum. With the help of such circles, it is possible to carry out processing metal parts, as well as stone and concrete elements. For a tree, such disks are not used.

Note! The use of angle grinders requires compliance with certain rules. One of them states that you can't use circles. larger diameter than indicated in the device passport.

Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.

These products are differentiated by one more sign - dimensions. The modern market provides wide selection products, the dimensions of which vary from 115 to 230 mm. The 115 mm wood grinder disc is the most compact and is used for fast and accurate cutting of material. It is worth noting that the largest discs are not suitable for working with wooden surfaces.

Types of wood discs for angle grinders: design options

Many experts do not recommend using a grinder for cutting and processing wood. This is due to the principle of operation of the device and the characteristics of the material itself. However, the variety of discs for angle grinders is growing every year. They can be divided according to the features of the work into several types.

Circular saws. Such wood circles for grinders are used, as a rule, for more technologically advanced equipment, but many install them on angle grinders. They are divided into two types: large diameter soldered and more compact, without soldering.

Chain. Ideal for working with wood materials. Many people are interested in the question of whether it is possible to saw a tree with a grinder. There is no single answer to it, however, chain products are maximally adapted for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. Such a design has many advantages. This nozzle is most commonly used for smooth cutting boards. With it, you can process other materials: chipboard, fiberboard, plywood.

Saws with a small number of teeth. This kind of circles was invented specifically in order to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones - 4. This group also includes cutting discs for a grinder on wood 125 mm. These products do their job well. They can be used to cut wood along and across the grain. In addition to standard functions, such discs are used to organize grooves in workpieces.

Segmental (material - tungsten carbide). Such products appeared relatively recently, but have already gained immense popularity. A distinctive feature of such products is the absence of teeth. The edge of the disk consists of segments that are characterized by high strength.

Useful information! With the help of a segment nozzle, you can work with wood of any strength and viscosity. It is highly safe and is able to withstand even metal inclusions present in some blanks (self-tapping screws, nails, etc.).

Chain saw blades for wood: application advantages

AT this case the saw circle is performed using a chain from a chainsaw. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency. chain disc on wood for the grinder is also considered the safest. Using this attachment greatly reduces the chance of injury if the tool jams.

If the disk hits a solid element of the tree (for example, a knot) during operation, then the chain is not destroyed. This is done by turning the base. Such nozzles are very popular when it is necessary to clean the trunk of a tree from bark and knots.

Wood saw blades for angle grinders with a chain are used for various kinds of work. With their help, you can remove tree branches, as well as cut boards of small thickness. Functionality chain products allow you to use them as peeling tools. They do an excellent job of removing the bark.

With the help of a saw blade, you can make an even cut of parquet boards, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material to be processed with such a nozzle should be no more than 4 cm. Otherwise, the device is likely to overheat.

Cutting disc for wood for a grinder: features

For the manufacture of such products are used special material- tungsten carbide. This is explained by the following: when working with a grinder, there is a possibility that it will break out of your hands, so the material of the circle must have high strength characteristics. The use of tungsten carbide can significantly increase the safety of work, but the cost of such products is quite high.

Disks this type may have a different arrangement of teeth. A variety of types of products on this basis allows you to choose the most suitable for specific situation nozzle. The shape and frequency of the teeth also play a very important role. The most common wheel size for working with wood is 125 mm. If you decide to choose the most universal option cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.

Useful information! Wheels that have straight teeth are best for working with soft woods. Boards from conifers are also processed using such nozzles.

These products may have teeth that resemble a trapezoid in shape. They are characterized by a wider operational scope and are used for cutting boards with an average density. With this wheel, you can cut the following materials:

USB plates;
wood fiber boards.

Saw blades for wood for this type of grinder have some design features, which are determined by their purpose. For example, during operation, products easily overheat, so they have special slots that can be empty or filled with copper. Such a measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots can be different, but not more than 2 mm. As for their depth, it does not exceed 20 mm.

Grinding disk for wood for a grinder: characteristics

With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out peeling works varying degrees of complexity. The modern market offers a wide range of such nozzles. They are classified according to several indicators: form, design and purpose.

Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove the excess part of the tree from the end surface of the board. They may have special spikes or crumbs.

Peeling discs for wood for grinders are also used to level the surface of the boards. Such circles are equipped with special spikes, which are placed on a flat plane. This feature is very useful, as it allows you to polish the boards from which the flooring is constructed.

On sale you can find peeling products consisting of twisted wire. They are usually called korshchekami. Such attachments for a grinder for woodworking are of two types, depending on the features of their structure. The first option provides for the presence of a base in the form of a glass to which the wire is attached. The second type is a disk with a wire fixed along the edge.

Brushes are used to eliminate paintwork materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.

Note! For wooden parts it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types of wood.

Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give wood unusual view, artificially age it. However, with the help of a grinder with a peeling wire nozzle, only small volumes of wood can be processed. Thus, for brushing in industrial scale this item is not recommended.

Grinding and polishing discs for wood on a grinder

Grinding and polishing wood is carried out using special nozzles that are used for grinders. Such products include metal base on which the grinding wheel is fixed. Fastening is usually done with Velcro.

To use such a wood attachment for a grinder, it is necessary to fix it with a key (open-end) on the tool shaft. Quite often, it is implemented complete with a special transition element, thanks to which it becomes possible to quickly attach to the drill chuck. In turn, polishing requires the use of a more gentle material. Therefore, nozzles of this type are equipped with felt discs. Their fixation is also carried out with Velcro.

Another option for a grinding wheel for a grinder is a petal one. Its design fully justifies its name. It is made up of many petals. sandpaper, located close to each other. If desired, you can select the desired paper grain, which allows you to process wooden materials varying degrees density.

Although the grinder is not considered the preferred tool for woodworking, sanding attachments are very common. It is worth noting that grinding in this way is not suitable for smooth surface treatment, since even the most gentle options for angle grinder discs leave small scratches on the wood. If you decide to perform this process as efficiently as possible, then experts recommend purchasing a special device - a grinder. Angle grinders are usually used for materials that will subsequently be painted with paint.

Grinding wheels for grinders on wood: rough grinding

Grinding wheels that are used for angle grinders differ in the material of manufacture, shape and operational purpose. The process of wood processing, as a rule, proceeds in two stages. First of all, rough grinding is performed, after which the material is subjected to finishing. For rough polishing, several types of nozzles are used:

peeling;
corsets;
end circles.

Grinding wood with a grinder using a peeling product is most often used to remove a layer old paint. Sometimes nozzles of this type are used to remove varnish if it cannot be removed manually. Such circles can have a different relief, the characteristics of which determine the efficiency with which the product will function.

Brushes are used for sanding different types of wood. Products that belong to this group are classified according to their design, the direction of the wire bundles and their diameter. Depending on the rigidity, they are also divided into types. If necessary, it is possible to select the right tool corresponding to one or another variant of grinding.

Useful information! For rough processing, a larger diameter wire is used.

End discs for grinding wood on a grinder are used when it is necessary to adjust the size of the part from the end. Often, such products are used for the usual alignment of the side surface with uneven cuts. The principle of operation of the end nozzle resembles the operation of a file. The difference in this case lies in the high efficiency of the angle grinder.

The use of grinding attachments greatly simplifies the processing of wooden blanks. Such products allow for the restoration old furniture, removing paints and varnishes from its surface.

Grinding discs for grinders: flap discs

After rough processing, it may be necessary fine finish. Of course, if the wood is to be further painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases, finishing is necessary action. To perform grinding, you can use a common nozzle - a petal circle.

The design of the petal disc model, as mentioned above, includes sheets of sandpaper that have a trapezoidal shape. Their grain size is selected depending on the type of wood and the specifics of the work. grinding disc on a tree of this kind is one of the most common. It ensures gentle handling of the material and is characterized by a high degree of safety. It is almost impossible to get injured using this disc.

The size of the abrasive coating on the petals determines the efficiency and speed of wood processing, as well as its appearance. For maximum smoothness, it is customary to use fine-grained products. Experts recommend using several of these grinding wheels on wood at once. This will make it possible to quickly carry out rough cleaning, and then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.

The use of such a nozzle requires a certain skill from a person. Therefore, before using petal circle it is recommended to practice on wooden parts.

Grinding wheel for grinders: soft processing and polishing

For soft grinding, special discs are used, which appeared on the market not so long ago - just a few years ago. Such circles are characterized by a high degree of functionality and can have different grain sizes.

Useful information! Unlike petal nozzles, abrasive particles are fixed with Velcro on the surface of the disc, and not on its end part.

Grinding disc for wood grinder of this type has one advantage - ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so using such discs is quite convenient. Sticky nozzles can be easily purchased on the construction market or ordered on the Internet. The choice of the desired grain size in this case is not a problem. With the help of such devices, you can bring the wooden surface to the desired state.

Polishing, which is carried out after grinding, can be carried out using special felt wheels. Such nozzles provide maximum smoothness of the work surface, which is difficult to achieve using other tools. A large number of speed angle grinder contributes to uniform polishing of wood.

Felt discs for the grinder include wool (tightly pressed), which can have different characteristics (depending on the need). On the modern market you can find various options for nozzles in their composition:

fine-haired;
semi-coarse;
coarse-haired.

Nozzles for wood processing differ in high efficiency and quality. Sequential use of these disks allows you to achieve incredible results. The wood surface after their use can be compared with a mirror.

Safety rules when working with a wood grinder

The use of angle grinders for wood processing requires a serious approach. Wrong work with a grinder can lead to injury, so before using it, experts advise you to pay attention to some rules for operating the device. For example, before replacing one nozzle with another, you need to disconnect the angle grinder from the network. How to change the disk on the grinder? To answer this question, it is necessary to determine the type of circle. Some products are installed without removing the main nozzle. However, in most cases, it is required to unscrew the flange holding the element.

Note! In no case should you remove the casing, which is used for protection, from the grinder. In the event of a wheel breakage, this element will protect your face and other parts of the body from injury from splinters.

Treatment wood material with the use of angle grinders must be carried out with protective gloves. Sawing and cutting discs for wood are best used on medium (in terms of power) devices. This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.

For sawing logs and boards, it is recommended to use nozzles that have fine teeth. The smaller their dimensions, the less effort will be required to cut. Among other things, it reduces the likelihood that hard wood fibers will meet in the path of the disc.

Any Bulgarian without fail must be equipped with a speed regulator, which must be moved to the minimum position. When working with cutting discs for a grinder, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.

Angle grinder can be used for wood processing, however, before use, you should study technical features various nozzles. Products that are used for grinding and polishing do not carry any danger and are easy to use. Blades for sawing wood material require careful selection. During operation, it is necessary to observe the safety regulations and not deviate from them.

Modern angle grinders, better known as grinders, are used for various technological processes during construction and renovation. When choosing a disc for a wood grinder, you need to consider important features not only tools, but also processed objects. As a rule, the device is used for cutting metal. However, a large number of different disks allows you to use it to solve other problems.

First you need to decide on the tool (grinder - the correct name is a chain angle grinder), which is planned to cut wood. It is known that the discs are made according to the standard sizes of the grinder. The smallest diameter is 115 mm, but this tool is rarely used. The widest selection of power tools on the market is designed to facilitate various kinds manual labor. If while working in professional field specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on expensive hand tools.

To operate the machine with wood, a special drive is needed.. Absolutely contraindicated for cutting abrasive and diamond, carbide wheels. This will not help to cope with the task, but rather lead to the destruction or overheating of the device.

When choosing woodworking universal accessories, you should know that there are not only cutting discs, but also grinding wheels. To clean the tree, use the petal circle for the circular. The working surface of such a device consists of several layers of sandpaper, which has a different degree of roughness. The lower the roughness, the softer the sanding. Flap wheels allow you to perform polishing, which depends on the degree of detail.

Grinding wheels and cutter for grinders should be High Quality, which affects not only the quality of the work performed, but also the safety of the master. Processing wet wood is prohibited, as the result of such manipulations can be unpredictable.

For roughing operations, which are often used as initial processing, special cleaning agents are used. They are necessary in order to remove a layer of paint from a painted surface.

For processing grinder and circular saw you need specially designed nozzles with which you can grind, polish and mill surfaces. The choice is up to the master.

You can use the following circles:

An abrasive wheel for wood, which is used to work with various surfaces. Depending on the thickness of the circle, it can be cut and polished.
The diamond wheel is designed to work with stone, concrete and other building materials. Such circles are divided into segmented and continuous. The first type, due to better performance and better cooling, provides improved performance. These discs can be used for minor metal cutting.
Regular circle. It should be noted that it is not recommended to use it for sawing wood products without experience. If possible, it is better to use another tool.

If you need to remove a layer of paint from wooden surface, it is necessary to install the nozzle on the grinder. There are many for sale various options. They all differ in form, design and the specifics of the work that can be done with this tool.

The next cutter, due to the fact that the spikes on it are installed on a plane, allows you to level wooden surfaces - for example, if two boards on the floor in the place of the final construction are on different heights. This defect is easily eliminated, and the boards are then in the same plane.

There are circles of twisted wire or in the form of a disk with wire windings clamped in the central part. In addition to this, the circle is often used to change the wood, it gives it a worn look. If such an effect is applied to wide surfaces in a professional environment, it is better to use special manual machines with wide details.

For grinding surfaces, there are special attachments consisting of a metal base on which an abrasive grinding ring is fixed. The circle is screwed onto the grinder shaft and tightened with a special key. Often it is equipped with an adapter for mounting in a drill holder or drilling machine.

To choose the right disc, first of all, you need to decide what material to work with.

Can be applied:

Thin blades (1-1.6 mm) are best for cutting thin sheet metal such as car body. When working with thicker corners, they can speed up the cut, but the risk of damage to the disc is greatly increased. In this case, it is safer to use thicker discs.
Rigid - most often used for active processing (cleaning) of welds after welding and gluing metal surfaces before welding. With their help, remove (cut out) braces and protrusions on the metal. They are also used in cases where the metal surface must be cleaned of rust or old paint.
Elastic - mainly used as an alternative to metal brushes. They perfectly clean even a curved metal surface from outdated paint and other similar coatings.
Coarse - used for grinding metal and wood. Even the smallest welds can be smoothed out with large discs (with the largest grit), but are mainly used for finer operations. They remove the faded top layer of wood surfaces, polish wooden beam, rust and outdated metal paint.
Abrasive - for concrete processing, there are somewhat fewer diamond discs, but they also have more short term services. Their use is justified only when it is necessary to perform a small one-time work.
Diamond blades are used for cutting various products made of concrete and stone (paving slabs, steps, curbs, facing stones), as well as bricks of all types.

For working with reinforced concrete stone materials turbo diamond blades (both conventional and wave) are best suited. When choosing, keep in mind that a turbo will provide a cleaner cut than a diamond wheel.

If the device has outside diameter only 125 mm, and the grinder is designed for 115 mm, it cannot be installed for the following reasons:

First, the discrepancy between the revolutions of the tool itself and the circle is dangerous for the user.
Secondly, when it heats up and expands, the disc can get stuck, resulting in a jerk.

The number of teeth matters. The smaller the number, the faster the work will be, but the quality of the cut will be less, and vice versa, a larger number increases the cutting time, but the ends of the resulting parts will be smooth.

FROM large quantity small teeth, the device will work with low efficiency. Large teeth allow you to work faster. The cost of a disk depends on outer dimension, number of teeth, manufacturer. The most expensive model- with a circular saw.

For many reasons, it is better to buy circles from well-known companies. The concept of "quality disc" includes not only the degree of rupture of the disc and its abrasive properties, but also safety.

When choosing a new wheel, it is worth making sure that it is designed for the speed of the grinder. Permissible speed is indicated.

You need to follow the rule: the larger the rasp disc, the slower the speed. In addition, manufacturers protect the user as much as possible by releasing discs with a large (sometimes double) strength. But if the disk is used more than necessary, all these measures lose their meaning.

work with a protective cover;
protect the face and head;
check lumber for nails and screws;
hold the device firmly by hand;
use an additional handle (many hold the device with one hand);
do not allow the tool to heat up, avoiding the risk of smoke.

In addition, if you do not plan to work with a grinder on a large scale, you do not need to buy a lot of discs “in reserve” - since the humidity contained in the air begins to affect the bakelite. The bond strength is markedly reduced. It is better to get the right wood discs for angle grinders (grinders) immediately before work.

The grinder, or angle grinder (angle grinder), is a very popular tool that is versatile. It is used in the process of performing most construction work. Many people are interested in the question of whether it is possible to cut a tree with it. To process this material, it is necessary to choose the right wood disc for the grinder. There are many varieties of nozzles, differing in characteristics and purpose.

The range of nozzles for this tool is quite wide. Products are classified according to their purpose, depending on which 3 main groups of circles for angle grinders can be distinguished:

saw;

Saw. They are similar to standard saws, but are made from other materials. The most common option is tungsten carbide discs. They are not suitable for woodworking.

Diamond coated. This group of circles for the grinder is the most extensive. The high popularity of diamond-coated nozzles is due to a wide operational spectrum. With the help of such circles, it is possible to process metal parts, as well as elements made of stone and concrete. For a tree, such disks are not used.

Note! The use of angle grinders requires compliance with certain rules. One of them claims that it is impossible to use circles of a larger diameter than indicated in the device's passport.

Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.

These products are differentiated by one more sign - dimensions. The modern market provides a wide selection of products, the dimensions of which vary from 115 to 230 mm. The 115 mm wood grinder disc is the most compact and is used for fast and accurate cutting of material. It is worth noting that the largest discs are not suitable for working with wooden surfaces.

Types of wood discs for angle grinders: design options

Chain. Ideal for working with wood materials. Many people are interested in the question of whether it is possible to saw a tree with a grinder. There is no single answer to it, however, chain products are maximally adapted for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. Such a design has many advantages. This nozzle is most often used to perform a smooth cut of the board. With it, you can process other materials: chipboard, fiberboard, plywood.

They can be used to cut wood along and across the grain. In addition to standard functions, such discs are used to organize grooves in workpieces.

Useful information! With the help of a segment nozzle, you can work with wood of any strength and viscosity. It is highly safe and is able to withstand even metal inclusions present in some blanks (self-tapping screws, nails, etc.).

Chain saw blades for wood: application advantages

In this case, the saw circle is made using a chainsaw chain. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency. A chain drive on a tree for a grinder is also considered the safest. Using this attachment greatly reduces the chance of injury if the tool jams.

Wood saw blades for angle grinders with a chain are used for various kinds of work. With their help, you can remove tree branches, as well as cut boards of small thickness. The functionality of chain products allows them to be used as peeling tools. They do an excellent job of removing the bark.

Cutting disc for wood for a grinder: features

For the manufacture of such products, a special material is used - tungsten carbide. This is explained by the following: when working with a grinder, there is a possibility that it will break out of your hands, so the material of the circle must have high strength characteristics. The use of tungsten carbide can significantly increase the safety of work, but the cost of such products is quite high.

Discs of this type may have a different arrangement of teeth. A variety of types of products on this basis allows you to choose the most suitable nozzle for a particular situation. The shape and frequency of the teeth also play a very important role. The most common wheel size for working with wood is 125 mm. If you decide to choose the most versatile version of a cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.

Useful information! Wheels that have straight teeth are best for working with soft woods. Softwood boards are also processed using such nozzles.

USB plates;
wood fiber boards.

Saw blades for wood for a grinder of this type have some design features that are determined by their purpose. For example, during operation, products easily overheat, so they have special slots that can be empty or filled with copper. Such a measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots can be different, but not more than 2 mm. As for their depth, it does not exceed 20 mm.

Sanding wood with a grinder using a peeling product is most often used to remove a layer of old paint. Sometimes nozzles of this type are used to remove varnish if it cannot be removed manually. Such circles can have a different relief, the characteristics of which determine the efficiency with which the product will function.

Brushes are used for sanding different types of wood. Products that belong to this group are classified according to their design, the direction of the wire bundles and their diameter. Depending on the rigidity, they are also divided into types. If necessary, there is the possibility of selecting the right tool, corresponding to a particular grinding option.

Useful information! For rough processing, a larger diameter wire is used.

The use of grinding attachments greatly simplifies the processing of wooden blanks. Such products allow you to restore old furniture by removing paint and varnish compositions from its surface.

Grinding discs for grinders: flap discs

After rough processing, a fine finish may be necessary. Of course, if the wood is to be further painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases, finishing is a necessary event. To perform grinding, you can use a common nozzle - a petal circle.

The design of the petal disc model, as mentioned above, includes sheets of sandpaper that have a trapezoidal shape. Their grain size is selected depending on the type of wood and the specifics of the work. This type of wood sanding disc is one of the most common. It ensures gentle handling of the material and is characterized by a high degree of safety. It is almost impossible to get injured using this disc.

The use of such a nozzle requires a certain skill from a person. Therefore, before using the petal circle, it is recommended to practice on wooden parts.

This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.

Any angle grinder must be equipped with a speed controller, which must be moved to the minimum position. When working with cutoffs, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.

Angle grinder can be used for wood processing, however, before starting operation, you should study the technical features of various nozzles. Products that are used for grinding and polishing do not carry any danger and are easy to use. Blades for sawing wood material require careful selection. During operation, it is necessary to observe the safety regulations and not deviate from them.

The modern grinder is often used to perform various works in the process of repair, construction. Such a tool can be called universal. The grinder easily cuts almost any object, grinds, sharpens, polishes and peels. To do the work with the help of a grinder, it is qualitatively necessary to select the right discs, taking into account the type of tool.

Discs for grinders on wood

Angle grinder (grinder) performs a wide range of different operations rotational movements interchangeable disks or nozzles. The most commonly used circles for metal, stone, wood. All of them are divided into three main groups:

Cut-off
Sharpening (cleaning)
Grinding (roughing)

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 wheel, you need to know how to work with them, because careless movements or inattention can lead to serious injuries. The protective cover on the disc serves as a 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 nozzles without a strong feed and try to permanently fix the angle grinder using a special device for this.

The most common can be circles on wood - milling cutters, they look like metal circles with teeth, they are specially made for cutting wood. Circles can be different in size, depending on the thickness of the timber, the diameter of the cutter is selected.

For sawing wood, only saw blades and right choice gives a wide range of possibilities. If you know how to use the tool, you can even make cutting at an angle.

Disc production

There are two types of saw blades for a grinder on wood - monolithic and with carbide soldering at the ends of the teeth. If there are such solderings on the saw blade, then they do not wear out so quickly, they do not require wiring, they cut better, but they need to be sharpened only on special machines.

For the production of saw blades, only carbide sheet steel. It guarantees the product high resistance to mechanical damage and temperature fluctuations. In the production process of the saw blade, great attention is paid to the weld, it connects the body of the blade with the teeth, so its quality is always under control.

The speed and frequency of cutting is affected by the number of teeth on the wheel, the greater the frequency of the teeth, the better the cutting of wood will be, 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.

Influence of disc teeth

The end 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 milling cutters with variable teeth, they work well with hard and soft woods. Products with trapezoidal teeth are only suitable for working with soft materials. For draft version fit circles with straight teeth.

When processing precious woods, you need to use thin saw blades, they are great for sawing or processing expensive wood. There are also "thin +" discs, where material is used with an additional chipper, it reduces blocking of the saw during its operation. This saw blade is suitable for longitudinal and cross cutting of wood and other materials. Similar materials from high precision cuts are also used in furniture and woodworking industries.

Features in working with saw blades

When working with a saw blade for wood, special care and skill must be exercised, it is best to put on special form and goggles and gloves. The complexity of working with wood lies in the fact that the tree is easier to cut, so it is necessary to observe control in the operation of the tool. Experts recommend using a tool of low power and speed when working with wood, the most best option- 1,000 rpm.

Equally important is the quality of the grinder, as well as the cutter, the final result of the work and its safety will depend on this. It is best to give preference to a proven tool, to hear the opinion of experts in order to be sure of a positive result.

grinding wheels

For execution various works with the help of grinders are made grinding and polishing wheels, they can be:

spongy
Felt
With replaceable sandpaper
Cloth

The material is selected depending on the surface to be sanded. To process wood species, petal grinding wheels are used, they are made of sandpaper, which is fixed on a rigid frame. Sandpaper can be coarse and fine grit, the markings can be seen on the product itself.

If planned make wood smooth, then it is best to use a fine grit wheel, to remove a small layer of wood - medium grit. If you need to remove old paint, then you need to apply a coarse-grained wheel.

According to their design, grinding wheels can be petal, movable and solid. Flap wheels give the smoothest surface to wood, therefore they are used as finishing circles.

Conclusion

When working with an angle grinder, you must always follow safety precautions. It is good when the tool is equipped with a persistent handle and a protective cover. Devices are considered safe, in the edge of which there is a chain from a chainsaw, it is specially installed there. In the event that one of the teeth is jammed, the disc rotates idle, and this reduces the risk of injury.

A wide range of power tools on the Russian market is designed to facilitate different types self made. If in the professional field the purchase specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on an expensive tool that, after doing a certain job, may not be useful at all. The most popular power tool is the angle grinder (angle grinder). The scope of its application is not limited to metal processing - grinding wood with a grinder is carried out using special nozzles.

For those who do not know "Is it possible to process wood with a grinder?" this article will be helpful. To perform grinding and polishing of wooden products or large surfaces of the array, you will need to purchase the appropriate nozzle - a circle. For grinders different sizes nozzles are selected, designed for a certain speed of rotation. Special discs designed for wood processing must be carefully selected. The disc must match the dimensions of the tool; a special nut is used to secure it.

When working with angle grinders, it is necessary to strictly observe safety precautions and use only factory wheels that are suitable for a particular model of power tool.

Coarse wood grinding discs for angle grinders

There are several varieties of circles that differ in shape, material of manufacture and purpose. As a rule, the wood blank must first be subjected to a rough surface treatment, after which it is subjected to fine or final detailing of the coating with abrasive segments.

For such work, a special attachment for a grinder for grinding wood is designed. The most requested are:

Roughing circles. This grinder attachment is best used to remove a layer of old paint. Suitable for lacquered finish which cannot be removed manually. It can be a wooden floor painted several times or a window sill. The design of abrasive discs consists of a disc and metal bristles made of elastic wire. Nozzles are available with different location steel bristles. Depending on achievement desired effect the villi can be placed along the entire perimeter of the disc parallel to the instrument or perpendicular to the segment - as in a conventional brush.

Cord brushes are a disk with a large abrasive coating designed to perform rough grinding and removal of irregularities on a wooden surface. With the help of this tool, the wood blank acquires its final shape. Productivity of works in comparison with the usual manual tool is much higher.

End discs. Nozzles are used when you need to align the product from the end. Such processing requires oblique cuts and the edges of the workpiece. The technique is identical to a file, but the abrasive is more effective than a hand tool. When working with a segment, it is important to have skills and then such a simple tool can completely replace moulder cutter in terms of edge processing.

With the help of a grinder for polishing wood, you can completely restore furniture covered with varnish and paint. After this stripping, the thickness wooden base practically does not decrease, but the newly painted furniture will look beautiful and impressive.

While doing grinding work grinder choice of tool is not so significant compared to the presence of well-dried wood and the absence of cracks on the surface.

Grinding wheels for gentle processing and their areas of application

To perform wood grinding with a grinder, nozzles of a universal design and with a special gentle coating are used. Such mechanical restoration intended for the production of certain works:

The petal disc is used for grinding the array. The design of this segment corresponds to its name. Its working surface is equipped with a large number of trapezoidal sandpaper petals that overlap each other like fish scales (three-quarter overlap of the previous row). With this arrangement of the petals, the abrasion of the nozzle occurs much more slowly.

This is the most common type of attachment for a grinder for wood grinding, which performs a soft surface treatment, and the tool itself is less traumatic. To achieve the desired degree of processing and high quality, the disc is selected according to the grain size. The size of the abrasive determines how quickly and efficiently the irregularities on the wooden surface will be removed.

The polished coating at different stages of processing may remain a little rough or be perfectly even without the slightest flaws and hooks. The final result can be achieved with a consistent transition from abrasive discs with a coarse-grained fraction to segments for finer processing. Therefore, you will need several discs per angle grinder for grinding wood, which will change in stages.

To use the petal nozzle, certain skills are required, which means that training before performing responsible work will be simply necessary.

Wheels for soft grinding. Universal nozzle on the grinder for grinding wood appeared on the market relatively recently and is distinguished by a special design and high functionality. Rough work is intended to perform removable disks with desired grain size, which are attached to the sticky base of the nozzle. In this regard, the abrasive tool received the appropriate name - sticky disc.

The main advantage of a wheel grinder for wood grinding is the quick change of a worn-out removable disc: the whole procedure takes place without removing the main nozzle, which is fixed with a nut. First you need to purchase a sticky attachment for grinding on a grinder, so that later, without any difficulties, you can replace the worn abrasive segment.

How to choose sanding attachments for an angle grinder

Circles should be selected according to the main parameters:

outer diameter (with large sizes, the processing process is accelerated and the service life is increased);
landing diameter (setting a circle of a larger size to a smaller one is possible using a special adapter);
thickness (the greater the thickness, the longer the segment will last);
grain size (the fraction must correspond to the type of processing: a coarse abrasive for rough work, and a fine one for soft processing and creating a finish coating);
type of segment (suitable for special nozzles for processing wooden surfaces).

Reference! The diameter of the shaft in modern angle grinders for wood is 22.2 mm.

What you need to know when working with a grinder

Renovation of the flooring (parquet), furniture or facade of the house, where there are wooden structures or individual elements, is performed using a grinder for grinding, which is equipped with different nozzles. Therefore, it is not surprising that angle grinders for polishing wood are in demand among professionals and in everyday life. But in order to choose the right tool for the job, you need to carefully examine the wooden surface for the presence of fungus, cracks and bumps. A video is provided to help beginners who want to know "How to properly grind a tree with a grinder".

For each model of angle grinder, it is mandatory to select grinding head, only in this case will the safe performance of work be guaranteed and high-quality processing surfaces. Before you start working with a grinder (wood sanding), you need to make sure that the disk is properly fixed. Move corner car on the surface it is necessary to smoothly and not allow vibration of the tool.

When working with an angle grinder for grinding wood, it is unacceptable to use discs of small thickness (high rotation speed and load lead to a break in the circle, which is fraught with injuries).

The cost of circles for woodworking

The price of a tool for polishing a wooden surface is not high, but depends on the material, diameter and thickness. The table shows average cost abrasive tool in major cities Russia:
