Bulgarian, or angle Grinder- an instrument that has no analogues in its popularity. If initially the scope of its application was limited to the operations that determined the name of the unit (grinding and technologically related types of material processing), then gradually the range of application of this power tool and the replaceable nozzles produced for it expanded incredibly. Now the grinder cuts metal, grinds various surfaces, cleans dirt and old paint and much more.
The presence of a rotating rod made it possible to adapt the grinder for sawing wood. They began to try to install saw blades manufactured for circular saws on it. Manufacturers of bits for this tool have responded by developing and producing special wheels, similar in action to circular saw blades, but adapted to the high speed and increased safety requirements of hand tools.
Features of the use of grinders on wood
Sawing wood with a hand tool is associated with a number of features. Wood is a heterogeneous natural material, its density is unevenly distributed. After a relatively loose area, a denser one may suddenly begin, there may be defects hidden in the thickness, filled sometime, in the process of tree growth, with resin. There may be developed or underdeveloped knots, and sometimes ingrown foreign inclusions (nails, wire, shot or even bullets that hit the tree while still in the forest, for example, during hunting).
Thus, it is almost impossible to unambiguously choose the mode of operation of a cutting hand tool. This can lead to jerks, the energy of which will have to be extinguished with the help of hands, in special occasions the instrument may even break free. If a cutting tooth hits metal, it can be broken and ejected by the next tooth with enough speed to cause serious injury.
Unlike circular saws (stationary or mobile), the grinder has a higher number of revolutions on the pulley, this is necessary to perform its main function - grinding.
When adapting this tool for sawing wood, the craftsmen often removed the protective cover, which is categorically unacceptable, given the above features of wood as a natural material with unpredictable variations in properties. If the need to use a grinder as circular saw nevertheless arose, in order to ensure safety and get the greatest effect, you need to purchase a special disc designed specifically for this tool.
Saw blades for angle grinders
Wood saw blades for angle grinders were developed by various manufacturers and, accordingly, have several varieties. The simplest and definitely the most a budget option- install on the grinder a disk for a circular of appropriate sizes - both the outer diameter and the diameter of the inner mounting hole. For a grinder, which, according to its dimensional characteristics, is classified as small, a circle of 125x22 mm in size is suitable.
Technically, a disk with a diameter of 230 mm can also be installed on a small angle grinder, but for this you will have to remove the protective cover, which is absolutely unacceptable. An angle grinder user's hands are in close proximity to the rotating work surfaces and any abnormal situation can cause serious injury. The use of such a circle on an angle grinder can cause serious safety violations and is strongly discouraged for beginners.
Any misalignment, including those associated with the uneven structure of the wood, can cause the disc to jam and, as a result, a sharp jump in the entire unit to the point that it can escape from the hands and make a dangerous unpredictable flight. The circular saw blade is not designed for such fast revolutions that the grinder spindle gives out, this results in its excessive heating, which affects the strength of the steel. As a result, damage can occur when skewed. saw blade with fragments flying at high speed in unpredictable directions.
Special attachments for sawing wood, designed for UMSh, have significant differences from the circular saw blade. Consider the most common nozzle options for sawing wood. On sale you can find saw blades similar to circular saws, which have an increased tooth set, which significantly reduces the likelihood of jamming. In addition, the difference for the manufacture of such a disc is that other alloys are used, which reduces the risk of destruction of the disc when it is heated.
Further attempts to secure the disc from jamming led to the combination of circular and chain saws in one product. A chain similar to a chainsaw chain moves freely along working surface disk, which absolutely eliminates jamming. There are quite a few modifications of such a hybrid. Craftsmen with the help of such a combined saw successfully saw branches and can even saw not very thick trees.
Another direction of adaptation of circular saws for use on grinders was to reduce the number of teeth. Discs with a diameter of 115 mm or 125 mm are equipped with only three teeth, a disc for a large grinder of 230 mm can have 4 teeth. In this way, manufacturers have tried to compensate for the high speed of rotation of the saw blade.
A completely new direction in the evolution of circular discs was marked by the invention of a special nozzle that is suitable for working on various materials. Such universal disc made of a special composition - tungsten carbide. There are no teeth on this saw blade at all. This type of disc allows you to cut well the most different materials, it can be considered the safest blade for sawing wood of all that are used on angle grinders.
Sawing with a grinder
If there is no other way out, that is, there is no special saw for wood (it has broken) or urgent little work is required, of course, the grinder can help out. However, we must remember that the main purpose of this machine is still not in sawing wood. To use an angle grinder as a hand-held circular saw, you will need to stock up on one or more specialized nozzles.
To avoid distortions and jamming, you need to saw in a comfortable position, and fix the tool with both hands. The best results can be obtained if you do not remove the special guide handle, with its help it is much easier to control the angle grinder. Correctly sawing off a workpiece with a grinder is not at all easy, due to the heterogeneity of the wood, the mode of operation will constantly change. Therefore, while working, it is better not to be distracted and monitor how the cut is going.
If it was necessary to use a grinder for sawing wood, it is better to use a circle not large diameter 115 or 125 mm. The 230th circles are much more dangerous, they have a large inertia, in case of an emergency situation, it is not possible to stop their rotation immediately. Installing the saw blade on the angle grinder \. the direction of rotation must be taken into account, it is often indicated on the disk itself in the form of arrows. The teeth of the circular saw have special solderings that increase their performance. A disk installed on the contrary will not be easy to cut. When purchasing saw blades for grinders, you need to pay attention to the following parameters:
- saw blade diameter;
- required depth of cut;
- shape and number of teeth.
If you plan to cut wood infrequently, then it is better to choose a saw blade with teeth that have a variable set. If the main material on which it is supposed to work is chipboard, a saw with a large number it is better not to take teeth. If the grinder will be used in the construction of a log structure, it is better to purchase a chain saw. Sawing boards will require paying attention to the depth of cut and the diameter of the blade.
A circular saw will last longer if the teeth that become dull during operation are sharpened, it is better to entrust this to a specialist. In order to sharpen the saw, the same grinder can be used only with a special abrasive nozzle. Also for this operation you will need a stationary vice.
Angle grinder - very useful tool, which can be used in various fields of production. It is due to its versatility that it has become widespread both at industrial facilities and at the household level.
Types of nozzles for wood
As a tool for woodcarving, only angle grinders with speed control are suitable. Since the main purpose of the grinder is the grinding of homogeneous materials, the processing of the heterogeneous structure of wooden materials must be approached very carefully.
The following types of circles for wood 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 a grinder consists of a metal circle with a chain attached to the edge. Design of special saw tools similar to those used on chainsaws. But saw blades are made of tungsten carbide. When a disk for a grinder on a tree hits a solid obstacle in the wood - knots, resin, metal, its base rotates without breaking the chain. With chain nozzles, it is quite easy to clean the logs from knots and bark, to give them the necessary initial shape.
Cutting discs
Various manufacturers also produce cutting wheels for wood specifically for angle grinders, for example, the Bosch cutting wheel. Their design is significantly different from the design of discs for circular saws. Usually they have side teeth that protect the nozzle from jamming. Cutting tools differ in the number and shape of teeth:
- bevelled;
- straight;
- in the form of a trapezoid.
The first version of the shape of the teeth is considered universal. It is suitable for all types of wood with small amounts of work. When sawing wood from soft varieties, it is quite possible to use discs for a grinder on wood with a straight tooth. Trapezoidal teeth are capable of processing quite solid products from wood: chipboard, fiberboard, OSB boards.
In addition, cut-off wheels vary in diameter. Minimum size- 115x22 mm. The most commonly used circles with a diameter of 125 mm, they are universal and suitable for a wide range of jobs. Maximum possible size- 230 mm. But the latter option is undesirable to use when working with wood, as the likelihood of injury increases. Depending on the size chosen, the depth of cut in the wood will also be different.
Disks - planers for grinders
It is possible to use the angle grinder as a planer. For this, special circles are used - planers. Work with such nozzles is allowed without a protective casing, since solid discs are not destroyed. Many brands of wheels can be sharpened repeatedly. Before use, an additional handle must be installed on the angle grinder to more securely hold the tool with both hands.
Grinding discs
This type of circles allows you to use the machine for its intended purpose. For finishing and polishing wooden surfaces can be used different kinds nozzles:
- cord brushes;
- end circles;
- petal nozzles;
- emery circles;
- cutting nozzles.
Rough processing of wood is carried out with the help of special cord brushes. end discs are designed to align the edges of parts, which is often required for oblique cuts of workpieces. They make a great file replacement.
The widest range of grinding attachments is for flap wheels. Depending on the size of the abrasive grain, the surface of the wood can be cleaned with varying degrees of polishing. 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 stacked with a three-quarter overlap on each other, wears rather slowly. If the relief surface of a wooden product is complex, then petal discs with a radial arrangement of abrasive strips are used.
Using sandpaper or sandpaper on a special nozzle allows you to grind quite large areas wooden surfaces. The ability to quickly change the sanding cover makes these tips versatile.
When deleting old coatings often use peeling nozzles. As a rule, 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 fixing the bristles on the perimeter of the disc.
When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, they must be cleaned to healthy wood.
Universal wood discs for grinder Graff Speedcutter
Wood disc for grinders Graff Speedcutter is Circular Saw with three teeth, which is intended for high-speed angle grinders. It is used in models with a maximum rotation speed of 12.2 thousand revolutions per minute.
The three carbide teeth are made of tungsten carbide and set at a 5° angle to the steel base of the tool. Thanks to this design and special form each tooth, the cut surface is very clean and even. A disc is being made for the Graff Speedcutter grinder with a size of 125x22.23x3 mm. The cutting width of the wood is 3.8 mm.
Designed Graff Speedcutter circles for artistic wood carving, cleaning and grinding various breeds tree. They are also used when cutting and selecting grooves in wood, its transverse cutting and longitudinal cutting. It is possible to use such nozzles when processing parts made of aerated concrete and gas silicate, fiberboard, chipboard, laminate, drywall.
Rules for working with the tool
Any tool can be a serious hazard if the instructions for use are not followed. specific situation. Bulgarian for cutting wood in this sense is no exception. The main points that are necessary when working with disks for an angle grinder - angle grinder on wood:
- Choosing the right circle size
- Installing a wood disk for a grinder
- Selecting the appropriate operating mode for the machine
- Refusal to use damaged circles
- Use of personal protective equipment
The nozzle size should be installed without problems under the protective cover of the machine. If this does not work, do not remove the protection. When working on wood with an angle grinder, it is necessary to use only special circles on wood for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or a damaged tool. In order to avoid the destruction of the disk on wood for the grinder, the speed of the grinder must correspond to that indicated on the surface of the circle. Before starting work, it is worth checking the wood disk for defects and damage. If they are present, then it becomes dangerous to use. When working with the tool, eye and hand protection must be used. It would be best to use tight overalls.
The angle grinder (angle grinder), popularly known as the "grinder", is a professional universal device that is used for a variety of purposes. With it, you can carry out a lot of work: cutting, grinding, polishing, saw cut and processing of various raw materials. When choosing a suitable model, you should understand its design features, assess your financial capabilities, and also consult with a specialist.
Due to the wide variety of existing models, the choice ideal solution could be a real disaster. In any case, the emphasis should be placed on the purpose of the proposed equipment. wooden structures need the appropriate grinding wheels for a wood grinder. The same applies to metal - it is processed only with suitable tools.
Varieties of grinding discs
Currently on sale big variety disks on a grinder, and it happens to a simple layman it’s not at all easy to choose a grinding wheel for a wood grinder. To understand the existing types in more detail, it is necessary to divide the range into the following categories:
- Abrasive wheels. Such consumables are particularly versatile, so it allows you to carry out accurate and high-quality events with minimal resource consumption. In addition, there is the possibility of additional polishing. Due to these characteristics, abrasive-type tools are one of the best.
- Circles with a diamond dusting - enjoy very wide popularity. Segmented and solid type models are available on the market. Depending on this option, the scope may differ. Both solutions are able to provide accurate cutting of any materials with the highest density. Among them: stone, metal and concrete products.
The blades for the grinder may resemble most modern saws, but they are made of other alloys. Initially, such goods were considered rare, but now they have spread very widely. Perfect option- combination of carbide and tungsten.
Woodworking discs
If you intend to purchase a wood saw blade for a bolarka, be sure to study the basic principle of operation of such a device. What features should be considered when purchasing a disk for angle grinder on wood?
The first thing you should pay attention to is the different standard diameters. Most compact solution has a size of 115 millimeters. However, many experts prefer to buy a wood disc for a 125 mm grinder, which is explained by great practicality. In addition, it is angle grinders on the 125th circles that are in special demand not only among representatives of professional fields, but also among home craftsmen.
It is no secret that a material such as natural wood is a specific heterogeneous raw material, so for its processing it is necessary to use different circles. Use classic models for metal or concrete structures Absolutely forbidden. If this is not taken into account, the tool will simply fail or burn out.
When choosing suitable products for grinding, pay attention to the diameter of the installed shaft. The standard value is 22.2 millimeters. Initially, there were several divisions, so the marking value remains quite large. At present, most standard models have a diameter of 125 × 22.2 mm.
And although the allowable size of the angle grinder is 230 millimeters, it is not advisable to give preference to such sizes for wood processing. When working with large products, you expose yourself to the risk of dangerous damage and injury. Ideal dimensions represented by the range 115x22.2 - 125x22.2 mm. Yes, and circles of class 125 are the most versatile, so they can be used to solve a wide range of production operations.
After a thorough study of the specifics of grinding discs for a wood grinder, you can proceed to the search for suitable models that will ensure the safest and most efficient processing of such a valuable material as natural wood.
Types of cutting wheels
When buying a cutting disc, take responsibility for choosing the “right” model and pay attention to a number of design indicators. Among them:
- circle diameter.
- depth of cut in wood.
- features of the teeth (shape, number, frequency).
If you want to use a cutting disc, consider the following recommendations:
In order not to make a mistake with the choice suitable solution, pay attention to the following selection features sawing consumable tools.
- It is necessary to choose rounded cutouts that are made strictly towards the shaft.
- Optimal Thickness disk is 2 mm.
- The depth of the cuts made sometimes reaches 20 millimeters.
- The cutout may be empty, but in some cases it is filled with a composition of copper.
Necessary equipment
In many cases, working with materials involves carrying out polishing, grinding, as well as peeling procedures.
It's no secret that cutting wood is a very dangerous occupation, but even an inexperienced worker can do sanding an array. The main thing is that he has the required equipment at his disposal. It is enough to understand the basic principles of the forthcoming work, and everything will be successful.
In most cases, flap discs are used for peeling. After a thorough study of the specifics of the product, you can be sure of its functionality and effectiveness.
From the name you can understand what are the features and principle of operation consumable tool. Its working area may have a small number of sandpaper petals. This structure may resemble fish scales. As for papers with a low roughness, they provide a soft polishing of elite woods.
The quality indicators and the degree of processing are determined by the grain size of the material, so polishing and grinding are performed taking into account the established requirements.
Despite the great popularity of petal models, you can use other expendable materials. For example, very good decision can become a sticky disk universal purpose. Most modern nozzles have the ability to quickly change Velcro. The cost of used sticky discs is much lower than the cost of solid petal discs, however, the low price characterizes a short service life. In any case, universal sticky models are effective both in processing and in grinding the most various materials which explains their great popularity.
Tool characteristics and work quality
Even if you have purchased the most expensive polishing and grinding equipment, this does not mean that the quality of work will be maximum. What is it connected with? It's very simple: for successful processing, you must use exclusively dried wood. Raw material is unsuitable for this kind of activities. If this feature is not taken into account, the result obtained may not be the most pleasant. When choosing a wood disc, make sure that the selected raw material matches established requirements and standards.
In some cases, it becomes necessary to carry out cleaning work to remove the old layer of paint, varnish or fungal formations. Good polishing and grinding tools always work the best way, however, provided that the material is prepared taking into account the basic technological requirements. You must understand that polishing and grinding discs for angle grinders are not suitable for primary processing operations, so they must be equipped with additional roughing attachments.
When choosing the right nozzle, you will be able to feel their effectiveness in those cases where you need to carry out cleaning old surfaces which are covered with several layers of paint. This result is explained very simply: most nozzles are a kind of metal plate, on which there is a wire bristle, placed closer to the outer circumference in a radial or perpendicular manner to the disk.
Finishing actions are started in those cases when the workpiece takes on a preliminary shape. The end result can be determined by the types of nozzles that are used in solving the problem.
An angle grinder can also be used as a cutter, as well as grinding and polishing machines. The expansion of functionality is provided by the use of different types disks.
And so, if you are faced with the question: “how to successfully polish or sand a wood structure”, be prepared to take a responsible approach to studying the basic subtleties and recommendations. As for the tools that will be applied in the future, they include:
If you intend to choose the right equipment for the grinder, consider not only the diameter, but also many other markings. With the help of inscriptions, you can clarify the exact purpose of the tool and select the best option for your purposes.
Modern Bulgarian is one of the most convenient and useful devices. To improve the quality of its work, it is necessary to take care of additional nozzles and discs that will make the processing of wood, metal, or any other raw material accurate and complete.
Bulgarian, or angle grinder (angle grinder), is a very popular instrument which 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;
- 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 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 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. 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.
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 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 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 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. Softwood boards 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 on an industrial scale, this element 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 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. 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 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 at once grinding wheels on wood. This will enable you to quickly rough cleaning, 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.
A grinding disc for a 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 these devices, you can 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;
