An angle grinder, if you know and correctly use all its capabilities, is a truly universal device that lends itself to almost any material. And if we are talking about processing wood on a large scale, then the “grinder” is much more effective than manual abrasive tools and fixtures. The main thing is to choose the right nozzle. This article will help you understand their main modifications and specifics of application.
Rough cleaning of wood
planer disk
Such a nozzle almost completely replaces this hand tool.
An irreplaceable thing, if it is required, for example, to make a rough processing of a log - when erecting a log house, preparing fence supports, and so on.
Application Features:
- AT this case the protective cover can be removed. Such a nozzle is one-piece, and its destruction does not occur. But protection from flying wood chips (glasses, tight clothing, gloves) is required.
- It is allowed to work only with a “grinder”, in which a second handle is provided (or installed). The angle grinder must be held when roughing wood with both hands.
Peeling disc
The main purpose of such nozzles is to remove the bark from the wood, to trim the workpiece. If the "grinder" is in capable hands, then with such a device you can make a sample of the material. For example, if you need to cut a bowl. If erected log house, then an angle grinder with such a nozzle perfectly replaces a carpenter's ax.
In some cases peeling disc cutting can be done. True, the cut will be wide, and there will be a lot of waste (chips, sawdust).
Milling
Disks
These nozzles are available in various designs. The main difference between the devices is the size of the abrasive grains.
They are not much different from rasps in terms of specific application. The difference is only in the speed of execution technological operation. With certain skills, it is advisable to use these for finishing wood.
cutters
They are, and specially for wood. The assortment is significant, since nozzles of this type differ in the configuration, location and size of the teeth.
Purpose of cutters:
- Selection of grooves.
- Edge trimming.
- Cup cutout.
- Sawing (for wooden blanks of small section).
Application specifics:
- When processing wood with such nozzles, it is forbidden to dismantle the protective cover.
- Each product has instructions. It clearly indicates for what types of work this nozzle is intended, the recommended speed of the grinder, and so on.
wood sanding
If you decipher the abbreviation angle grinder, then it is clear that it is the finishing that is the main purpose of the grinder.
cord brushes
They are mainly used for primary (rough) grinding of wood, when it is required to smooth out the irregularities of the sample.
End discs
The names speak for themselves. Such nozzles process the final parts of wooden blanks (cuts). Especially effective if you have to deal with angular (oblique) cuts.
Petal nozzles
The most used grinding devices for the grinder.
Such nozzles are applied sequentially, so several of them will be needed to process wood. Grinding begins with a disc with a "coarse" abrasive, and gradually the size of its grain must be reduced. Consequently, the devices in the process of working on the "grinder" periodically change.
grinding wheels
Most universal fixture to Bulgarian. It alone is enough for varying degrees of grinding. The nozzle itself is metal base, on which circles with one grain or another are attached. They are easy to change, or as they wear out, or in the event of a transition to another area of work. Therefore, only circles and are consumable. The nozzle itself is used indefinitely.
Application specifics:
- Wood grinding.
- Parquet scraping.
- Edge and end processing.
- Cleaning wood before painting.
wood polishing
For these purposes, brushes, disks, circles are used. Their "working elements" can be made of sponge, felt, fine-grained "sandpaper" and a number of other materials.
The article provides examples of only the main types of nozzles for the grinder. There are quite a lot of products of this class, so it is easy to choose the best option for processing any wood. The author hopes that the information provided will help the reader in this.
On a note!
Wood processing also means its cutting (sawing). Sometimes, in the manufacture of piece parts, you have to adjust them at the installation site even before you start grinding the sample. Some "craftsmen" (and there are many of them among friends and on the Internet) are advised to use for such operations. It is strictly forbidden! Here are just the main reasons why this should not be done.
- "Bulgarian" - a high-speed machine. And although the metal from which the cutting discs are made is durable, in this mode it does not withstand for a long time. More precisely, cutting edges (teeth), which are fixed by soldering. With intensive work, they fall off and scatter to the sides, and with great speed. The consequences are easy to predict.
- Not all discs are suitable for installation on angle grinders in terms of size (primarily, outer diameter). So, you have to dismantle the protective cover. The same thing - you can forget about the safety of the employee.
- The structure of wood (even hardwood) is quite loose. Therefore, it is highly likely that the saw blade may jam due to constant vibration. How the “Bulgarian” will behave in such a situation, given its power and speed, no one will undertake to predict. But the fact that it breaks out of hands quite easily is unequivocal.
- Constant changes in the mode (for the same reason - the viscosity of the lumber) lead to a systematic overheating of the angle grinder engine. With this use, the "grinder" will not serve for a long time.
That is why wood processing with its help is carried out only superficially - rough sweep, grinding, brushing. And for cutting you should use sawing tools and mechanisms (hacksaw, circular saw, electric / jigsaw, and so on).
It's like a fairy tale about a unicorn, everyone has heard about it, but no one has seen it with their own eyes. The public of construction forums and authors of similar articles on the Internet is divided into two camps. The former say that in their life they sawed more than one cubic meter of wood with a grinder, the latter give strong arguments in favor of the fact that after such work you can miss your fingers or limbs, or even worse. Is there a disc for a wood grinder and if so, what does it look like and is it safe to work with it?
The author of this article kindly asks you not to consider this material as a guide to action. An angle grinder is not designed to work with wood, even those manufacturers that produce discs and cutters for wood write on their official websites that it is extremely unsafe to cut wood with a grinder. But we all know that people rarely think about their health in the first place.
Cutting with an abrasive disc
Yes, it’s possible to cut a tree with a metal disc, to be honest, I myself, working at a construction site, have done it more than once. What can be said? Well, firstly, the speed of work with this method is low. Secondly, the smell of burnt wood even on outdoors within a radius of 10 meters you are provided. And thirdly, the thickness of the sawn board should not exceed four centimeters. This is not to say that the abrasive disc is not a wood disc for a grinder, its main purpose is to cut metal. As for the pros, in my opinion it is: the absence of sawdust, and a smooth, even cut.
Circular saw blade and its improved counterpart
The vast Internet is full of video materials on how to turn a circular disc or a diamond disc for concrete into a disc for working with wood. You can argue for a long time about whether it is worth doing or not? Even without considering himself helluva lot smart person, I would not conduct such experiments. And that's why:
- disk circular saw not designed for high speeds, yes, it is carbide, but no less fragile. A single chipped tooth can pose a great danger to a person.
- the edges of the toothed disc are not smooth, crashing into a tree, the grinder will vibrate and crash into the branches of the workpiece. this operation may cause the operator to lose control of the tool.
- increased chance of a kickback
There is an adapted disc for a wood grinder on sale, the manufacturers claim that due to the shape of the tooth and special expanders that are on the cutting part of the disc, all of the above concerns about tool jamming disappear. One of the manufacturers is the company Rotarex, in its assortment you can find both grinding and cutting discs for grinders. Below is an image of a circular disc and a grinder disc from Rotarex, which is universal. They can cut not only wood, but also aerated concrete.
Chain disk for wood grinder
At first glance, it may seem that this is a device for a horror movie, but judging by the reviews of the owners, this disc is safer than the analogues presented above. It is a solid circle, along the edges of which there is a chain from a chainsaw, everything is made of high-quality tool steel. The main purpose of such a disk: milling, modeling, stripping wood from bark and cutting cups in a log for log cabins. It is also possible to cut with such a disc, given that the width of the cut will be about eight millimeters, since the thickness of the chain disc is six millimeters. Speaking of diameters, there are 125 and 230 discs for sale. The service life of such a disc will be many times longer than that of others, since it can always be sharpened with a file. The price for them ranges from two to three thousand rubles, and even more will come out with delivery from another region.
Remember safety!
Whatever disc you work with and whatever material you cut, you should always remember that compliance with safety regulations can save you not only health, but also life. And before you get started, read the following points:
- not work in state alcohol intoxication;
- when working, use safety glasses and overalls;
- never remove the protective cover;
- it is forbidden to use a defective cutting disc or a disc with some, even minor, defects;
- when working with a grinder, hold it with both hands;
- the electrical cord must be at a distance from the rotating disk;
- do not put the tool down until the blade comes to a complete stop.
There are a lot of ways to cut a tree, one of them is to make a cutting disc out of paper. How effective this is, of course, is up to you to judge, but note that this is one of the safest options.
Bulgarian, or angular Grinder(angle grinder), is 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-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 125 mm wood grinder. 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. Distinctive feature such products - the absence of teeth. The edge of the disk consists of segments that are characterized by high strength.
Helpful 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.
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, 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.
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 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.
Helpful 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 with 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 a 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 of 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, 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.
Helpful 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 a necessary step. 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 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 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.
Helpful 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. Choice desired grit 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.
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. While working with cutting discs for an angle grinder it is very important to observe 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.
The grinder, or angle grinder, is a tool 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 is cutting metal, grinding various surfaces, cleaned of 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 high speeds and increased safety requirements. hand tool.
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, such as natural material with unpredictable properties. If the need to use the grinder as a 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, when skewed, the saw wheel can be destroyed 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. The chain, similar to the chainsaw chain, moves freely along the working surface of the disc, 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 of evolution circular discs was marked by the invention special nozzle which is suitable for working on various materials. Such a universal disc is 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 most safe disk for sawing wood from 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. For use of angle grinders as a manual 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 you need to use a grinder for sawing wood, it is better to use a circle of small 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 an angle grinder, you need to pay attention to following options:
- 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 have 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.
Bulgarian or angle grinder allows processing various materials, including wood. When it becomes necessary to cut metal, resort to the use of abrasive disc to Bulgarian. If you need to cut a brick or ceramic tiles then come to the rescue diamond discs due to high strength and durability. What to do if you need to saw or grind wood? To do this, you will need to purchase a special disc for a wood grinder.
Initially, you need to decide on the tool with which you plan to cut wood. It is known that discs are produced under standard sizes Bulgarians. The smallest diameter is 115 mm, but such a tool is used in extreme cases. The main advantage of such a grinder is its compactness, but it is extremely inconvenient to work with such a tool for a long time. The best option for woodworking - this is a grinder with a 125 mm disc. It is this size of the circle for wood that is the safest, and therefore it has become widespread.
To work with angle grinders on wood, a special disk is required. It is strictly contraindicated to cut wood with abrasive or diamond circles. This will not help to cope with the task, but rather lead to the destruction or overheating of the tool. When choosing a circle for a wood grinder, it is important to pay attention to the inner diameter of the shaft, which, according to the standard, is 22.2 mm.
It is important to know! Older models of angle grinders may have a different shaft diameter, so this point is important to consider when buying the appropriate circle.
