Bulgarian, whose real name is an angle grinder, angle grinder is a universal tool. Without it, almost never do construction work. But in order for the tool to last a long time, it is necessary to choose the right grinding discs. A disc for wood is fundamentally different from a disc for metal. What are its features, and what are the varieties?
To date, the entire range is divided into three main areas:
- Saw discs. They resemble a regular saw, but are made from completely different materials. Until recently, such copies were not found, but now they are sold completely freely. The most preferred option is tungsten carbide.
- Disc with diamond-coated. The most popular variety. In turn, it is divided into continuous and segmented. The scope of their application is different, but there is common feature- high-quality and accurate result of work on concrete, metal or stone.
- Abrasive. Universal consumable suitable for any type of surface. Qualitatively cuts and grinds, and also polishes.
Of the listed discs, the first and second are not suitable for wood. Natural wood has a very dense structure, and if you use diamond disc, then the grinder will overheat until it breaks.
Also, the products differ in diameter. The most practical ones have a diameter of 125 mm, in rare cases a compact disc is needed - 115 mm. There are specimens up to 230 mm, but they are not suitable for wood. Their use may result in injury.
Choice of cutting wheels for wood
Cutting discs are divided into three parameters - diameter, depth of cut and shape / frequency of the teeth. Choosing desired option, there are several things to consider: how often the product will be used and for what kind of wood.
Coniferous and other soft wood easy to cut with straight teeth. If you plan to cut different wood, it is better to take a universal circle with variably beveled teeth. There are also trapezoid teeth which are ideal for sawing through medium density wood and solid woods.
Choice of grinding and polishing wheels
If cutting material requires certain skills, then almost anyone can grind. This operation is usually used petal discs. Such a disc consists of several petals of emery, arranged in a circle. Sandpaper provides soft sanding.
Another option is a Velcro abrasive disc. 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 way sandpaper processing. For example, using such a circle, you can polish parquet.
Tree preparation
Whatever the disc for the grinder, the work cannot be done well if the wood is not properly prepared. Here are some tips for this:
- the tree must be thoroughly dried;
- special peeling nozzles are suitable for removing paint or varnish from the surface;
- work is carried out in two stages, roughing and finishing.
Discs and other tools that you will need for full-fledged grinding or polishing of wood:
- Cord brushes designed for rough surface grinding. Helps to give the workpiece an acceptable shape.
- The next step in processing a natural wood blank 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.
As you can see, when using various nozzles, the grinder becomes universal tool for woodworking.
Saw (chain wheels)
Suitable for cutting boards less than 4 cm thick. Use requires extreme care. During non-working hours, the disc should be kept in a case, and during operation it should be used only at those speeds that are written on the product itself.
Goggles and protective gloves are also required when working. It is important to remember that on the grinder, in no case should you use ordinary circles intended for circular saw.
Using an angle grinder for milling
A wood cutter for a grinder in non-professional hands can be dangerous. For a specialist, its use is permissible.
The cutter helps to level the edge, make grooves, cut blanks and cut out bowls for log cabins. Even on inhomogeneous wood, the tool will not jam or kick back. However, before using it, it is important to carefully read the instructions, as well as observe the necessary speed.
The choice of cutters for angle grinders is quite wide, no less than for a manual milling machine. They are not designed for precise processing, but are quite suitable for shaping.
Safety rules during work
In order for the use of a wood disc for a grinder to bring only benefits, and not injuries and damaged products, several important rules must be observed:
- choose the right circle according to size and properties;
- the mode of operation of the machine must comply with the requirements on the disk;
- in no case should you use damaged circles;
- protect your hands and face with special devices and overalls.
The nozzle should fit effortlessly under the casing of the angle grinder. If you cannot do this, then do not remove the casing, it is traumatic.
Why can't saw blades be used with an angle grinder?
The hardness of a tree can be different even within a few centimeters. Also, it can come across clots of resin and knots. All these uneven areas lead to the fact that the saw blade stops abruptly, as a result, the angle grinder breaks out of the hands.
Wood is a specific heterogeneous material that requires special wheels to work with. Discs for grinders for metal are categorically not suitable for cutting wood! Otherwise, the disk may be destroyed during operation.
The saw blade for wood for a grinder is the same as for a circular saw, but of a smaller diameter. In most cases, discs with a diameter of 115 mm and 125 mm are used, which can be bought in our online store.
Attention! Working with a saw blade is extremely dangerous and requires skill with an angle grinder and great care. When sawing, it is possible for the blade to jam in the wood, which will lead to the tool being pulled out of your hands and serious injury. It is categorically impossible to cut wood with a grinder "on weight". The tool must be securely fixed on the table.
Choosing a saw blade for a wood grinder
When choosing a saw blade for wood, pay attention to the shape of its teeth, which can be alternately beveled, straight and trapezoidal. In our online store you can buy wood circles for a grinder with variable beveled teeth with a diameter of 115 and 125 mm. They are suitable not only for sawing wood, but also for cutting aluminum and laminate.
Another factor to pay attention to is the number of teeth on the disc. The higher the tooth frequency, the cleaner the cut will be.
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 coating;
- 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 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 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.
By using saw blade you can make a straight cut parquet board, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material 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 work of 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 remove paint and varnish 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 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
Wood sanding and polishing is done by special nozzles that apply to the grinder. 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 consists of a large number of sandpaper petals, closely spaced to each other. If desired, you can select the desired paper grain, which allows you to process wooden materials varying degrees density.
Despite the fact that 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, it is produced rough grinding, after which the material is subjected to finishing. For rough polishing, several types of nozzles are used:
- peeling;
- corsets;
- end circles.
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, 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 you to restore old furniture by removing paint and varnish compositions from its surface.
Grinding discs for grinders: flap discs
After rough processing, it may be necessary fine finish. Of course, if the wood is subsequently 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.
From size abrasive coating on the petals depends on 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 a 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 the 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. These tips provide maximum smoothness. working surface which is difficult to achieve with other tools. A large number of revolutions of the angle grinder contributes to uniform polishing of the 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.
Woodworking attachments are different 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 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 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.
Quite often, the grinder is used for processing various kinds material. Some sources claim that it is strictly forbidden to work with this power tool on wood, while others say that it is possible, but only taking into account some nuances. One way or another, an angle grinder is used in carpentry. Therefore, the question of using a wood cutter for a grinder remains relevant.
The saw blade with chainsaw chain elements allows you to cut boards up to 40 mm thick, and it is important to be extra careful. Violation of the rules can lead to injury:
- Protective covers on the tool must not be removed. At large diameter disks exceeding the dimensions of the casing, the grinder cannot be used.
- work corner grinder necessary in compliance with the speed indicated on the cutting tool. If they are exceeded, the chain may slip, which will lead to the scattering of its constituent parts.
- Protective goggles and thick gloves are a must. It is also recommended to work in dense tarpaulin clothing.
It is forbidden to work as an angle grinder with installed disks that are intended for circulars. Because it poses a threat to human health and life.
This ban also applies to diamond cutting discs for concrete. To work with wooden products they are not safe because they are not designed for that. The efficiency indicator from their use is quite low, considering the cost of disks. And also there is a possibility of charring the product and simply ruining it.
And most importantly, there is a possibility of such a disc jamming at the processing site, which will lead to the tool flying out of the hands and possible injury.
With such a disc for the grinder, which is shown in the figure below, you should work as carefully as possible when processing wooden materials. Its design provides for protection that prevents jamming of the side teeth, which contribute to the expansion of the cutting width. The disk has a diameter of 115 mm, and thanks to its dimensions it is possible to work with the protective cover installed.
Some home-grown "masters" practice fitting standard saw blades for circular saws for angle grinders. All work is done with protective covers removed. Often the ending of such experiments is rather tragic. Unfortunate masters receive serious injuries that threaten life.
But despite this, the construction markets are full of offers that allow you to purchase. Inexperienced craftsmen are convinced by sellers that when correct use there are no risks associated with such tools. All this is true, exactly until the moment when nothing bad happens.
No professional shops will ever sell a person a grinder disc that may also be suitable for working with a circular. For such sales, if the buyer is injured, the seller may be held criminally liable.
The list of the main reasons why the use of a circular saw to work with an angle grinder is unacceptable:
- discs are designed to work at low speeds, the material of such a cutter is quite fragile. In the process of work, there is a possibility of the tool breaking into small pieces or spalling of the teeth soldered on the disk, which fly off at great speed;
- the wood has a rather viscous structure, in connection with this, the bite of the teeth occurs in an uneven way, which leads to vibrations and the mobility of the tool. This can lead to loss of control of the angle grinder and cause serious injury;
- jamming of the discs occurs during the working process when processing wood, the tool can be pulled out of the hands. Please note that the included tool with a rotating disc is unpredictable.
- uneven loads caused by work on wooden surface may cause the power tool to overheat, resulting in damage to the power tool.
The best solution is to manufacture a stationary sawing machine, on which the grinder will be securely fixed. absolutely simple, you need to prepare only the main components for this equipment. But it is definitely worth it, you will not only reduce the time for processing products, but also protect yourself from bad consequences.

An informative video from an expert about the Speedwood LEMAN saw blade for an angle grinder.
We carry out rough processing of wood with a grinder
But, despite the existing warnings, it seems possible to process a wooden blank with an angle grinder. This requires the use of special nozzles, which are manufactured in working conditions, and strict observance of safety regulations in the process of working with the tool.
Using planer discs for grinders
Roughing a log house involves the use of special discs that allow you to perform the function of a planer. This kind of wood processing using angle grinder considered one of the safest if you follow the operating instructions. The device is a good alternative to a carpenter's axe.
The nozzle is used without the installation of protective covers, since the fact that it can be destroyed during operation is completely excluded. You cannot use such a disk if it has an upward position.
When using the grinder, it is imperative to provide for the installation of a handle on it, which will allow you to hold the tool with both hands.
It is also necessary to have tight overalls and means personal protection who can protect open areas skin. When cleaning wood, you may encounter large chips that can easily injure the skin. One of the positive side effects from the use of such a power tool, ease in chopping chips or large sawdust, if any, is necessary for household needs.
Application of grinding discs
To remove the bark from a tree trunk, and give it a primary shape for blanks, a number of special peeling nozzles are used for corner grinder.
Thanks to this chain circle it is possible to clean the trunks from bark or small knots. And also the required shape is given to the blank material for further processing using more precision instrument. Such devices can replace axes for carving bowls in logs for the construction of buildings from a wooden frame.
You can also use this disk as a cutting wheel, but the resulting cut will be jagged and the material loss is too high due to the large thickness of the cut.
Using milling cutters on angle grinders for working with wood
After completing the roughing, you should proceed to the next step in the processing of wooden blanks - milling. For this purpose, some types of special nozzles are used.
The size of the abrasive on the discs can be completely different. Using this cutting tool should take into account its purpose. By means of such mills, it is easy to carry out giving of a final form to preparations. Some craftsmen use such nozzles to finish the wood, and the results from such work are quite good.
Almost similar types of discs are a mechanized rasp. They are considered relatively safe tools that do not require special precautions and compliance with certain conditions. You just need to take care of the protection of the eyes and respiratory organs.
If you need to perform the usual cutting of wood materials, then it is better to use simple circular, chain and reciprocating saws for this, and not a grinder. Also, the task can be effectively performed with an electric jigsaw.
It should be noted that the alternative electric tools for sawing boards and logs is homemade equipment. Fabricate to run simple tasks quite simple, so it is not necessary to use dangerous and expensive tools for simple tasks.
Milling a tree with a grinder: which cutters can be used
It requires careful observance of security measures. Similar work with a cutter using an angle grinder belongs to the class of dangerous, but acceptable when correct execution relevant recommendations.
A cutter on a grinder for working with wood is used to make grooves, rough edge alignment, cut out bowls for log cabins, and even for sawing blanks. It is possible to use only those cutters that have a special design that excludes the process of jamming and tilting of the power tool due to the heterogeneity of the wood. When using it, it is recommended that you read the instructions without fail, in particular about sections with maximum revolutions and the direction of movement of the cutter in relation to the position of the angle grinder.
Milling attachments for angle grinders are not inferior in their range to attachments for manual milling devices. Naturally, it is almost impossible to achieve a similar quality of material processing with a grinder, but it is quite possible to make a selection of suitable nozzles in order to give a suitable shape to the product.
Video "Is it possible to cut a tree with a grinder"
Video review on the use of a grinder for cutting boards and beams. How to cut a tree with a grinder and whether it is possible to do it - you will learn in this video.
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 with rotational movements of replaceable discs 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 valuable breeds wood, 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. For the processing of wood species, petal grinding wheels, they are made of sandpaper, which is fixed on a hard 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 circle.
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.
