How to choose a wood saw blade for an angle grinder? Wood saw blades for a grinder

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 angle grinder has a higher number of revolutions on the pulley, which 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 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, 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 differences 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 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 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 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.

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:

• a circular saw blade is 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 the 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 disk, given that the width of the cut will be about eight millimeters, since the thickness 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 the wrong cutting disc or a disk with some, even small, 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 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's 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.

The optimal circle for woodworking has the following parameters: 125x22.5 mm. Bulgarians for discs from 150 mm and above are not recommended for wood, as the risk of serious injury increases. It is better to use tools for cutting or grinding wood under 125 or 115 circle diameters.

Varieties of grinding wheels for wood

When choosing nozzles for a grinder for woodworking, you should know that there are not only cutting discs, but also grinding discs. For grinding wood with an angle grinder, it is used petal attachment. Working surface such a consumable consists of several layers sandpaper, which has varying degrees roughness. The lower the roughness, the softer the sanding can be. Flap wheels allow you to carry out not only grinding, but also polishing work, which depends on the degree of granularity.

In addition to petal, there are also such types of nozzles that are very popular - these are sticky discs. They are known for their versatility, as they allow quick replacement using a special Velcro. The cost of such consumables is much lower than that of the first option, but at the same time they have a shorter service life.

Grinding and polishing discs for the grinder must be of high quality, which affects not only the quality doable work but also on the safety of the master. The quality of wood processing is influenced by such a factor as the degree of its dryness. Processing raw wood is prohibited, as the result of such manipulations can be unpredictable.

If it is required to carry out peeling works, which are often carried out as initial processing, then special peeling nozzles are used. They are mainly used for those purposes to remove a layer of paint from a painted surface. Such nozzles are metal plates, inside of which there is a metal bristle made of wire.

It's important to know! It is not difficult to carry out grinding or polishing wood with a grinder, but it is important to observe safety precautions.

Varieties of cutting wheels for wood

If you need cutting discs for a grinder for wood, then you should initially pay attention to such parameters as the diameter of the circle, the depth of cut and the characteristics of the teeth. Depending on the wood material, a wood saw blade with the following teeth must be used:

1. Universal or beveled wood saw blades for grinders are best used if it is planned to carry out work rarely in extreme cases, and any type of wood can be used as processed materials.
2. Wood discs with straight teeth are recommended if technological process provides work with coniferous and soft breeds of wood.
3. The trapezoidal shape of the tooth is suitable for cutting medium-density chipboard. Most often, such a tooth is universal and suitable for sawing hardwoods.

Features in working with saw blades are due to the following factors:

• The thickness of the circle must be within 2 mm.
• The depth of the cuts made can be within 20 mm.
• Cutouts can be empty or filled with copper.(!)

It's important to know! When working with saw blades or cutting discs for wood grinders, you should be especially careful and careful. Without special need and experience, it is better not to carry out such work or replace them with other tools.

What you need to know when working with angle grinders

Not only power tools, but also hand tools are a serious danger if safety rules are not followed. The nozzle on the grinder for cutting wood in this case is no exception. At the work of the angle grinder With woodworking discs, it is important to pay attention to the following points:

1. Choose the right circle for the tool: according to the diameter of the outer and landing, and also depending on the type of wood.
2. Select the appropriate operating mode for the tool.
3. Do not use wheels that show obvious signs of damage.
4. Resort to application individual means protection.

It is not necessary to carry out work without the use of a protective cover, with the exception of carrying out manipulations for peeling, grinding and polishing wooden surfaces. It is especially dangerous to work saw blades. It is strictly forbidden to resort to installation on angle grinder discs from a circular or other instruments. For angle grinders, you can only use consumables that are directly intended for it.

In conclusion, it should be summed up and noted that grinder wheels for woodworking are no less popular than abrasive wheels. After all, the use of such consumables greatly facilitates the work of a person, and also significantly saves time.

Angle grinder - universal fixture, with which you can work with any material. Perform cutting, peeling and grinding operations. Among the people, she received the name Bulgarian. When handling the tool, you need to carefully select the circles. It depends on the size of the equipment, the rotational speed and the type of surface to be treated.

A variety of discs for grinders

The range of discs for angle grinders is great. When buying, you need to understand well what discs are for grinders. They differ depending on the work performed:

Characteristics and choice of circle

When choosing a circle for an angle grinder, you need to take into account what material will be worked with. In this regard, several factors are taken into account:

Sometimes there is a desire to install circular circle to Bulgarian. This cannot be done. The reasons are as follows:

Cutting disc for wood

The cutting disc for wood for grinders is made of high-strength alloy. When choosing, you need to be guided the following rules:

• Hard wood requires the use of an variably beveled wheel.
• For softwoods and softwoods, a straight tooth is used.
• Medium-hard rocks lend themselves to cutting a trapezoidal tooth.

In progress circles are heating up. It is not always possible to cool them down. Therefore, slots are made from the side of the teeth to the axis. They are 2 mm wide and 20 mm deep. Sometimes they are filled with copper. expansion is compensated. This prevents deformation of the metal.

Rough stages of work

At the first stage, the blanks are peeling. To do this, there are nozzles on the grinder for working with wood:

Gentle discs for wood

These are nozzles universal type. They are used depending on the work performed:

Tool cutter features

The cutter as a nozzle for the grinder is allowed for use, but requires precautions. With its help, you can make grooves, roughly process the ends of the workpiece or saw it. In the process of work, its jamming is excluded, but you need to know at what speed it is allowed to use it. It is important to consider in which direction the cutter is rotated relative to the location of the angle grinder.

The surface quality will be somewhat different from working on milling machine. However, the necessary operations can be done.

Using a chainsaw chain

If put on chainsaw chain on disc, you can cut boards up to 40 mm. In doing so, care must be taken. To avoid injury, you must adhere to the rules:

• Do not remove the protective cover. If it interferes with the installation, then the equipment cannot be used.
• The RPM value is set according to the one indicated on the disk. Otherwise, the chain will jump off.
• Work is carried out in protective glasses and gloves.

If it is necessary to work with wood, it is possible to use attachments for a grinder for wood processing. However, you must first read the instructions. Such work has its own characteristics. If you ignore them, you can easily get hurt.

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 must understand its design features, evaluate your financial capabilities, as well as 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 quite difficult to choose grinding wheel for grinders on wood. To understand in more detail existing types, it is necessary to divide the assortment into the following categories:

1. Abrasive wheels. Such a consumable is 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.
2. Circles with diamond-coated- are very popular. 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 professional areas 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. Standard value equals 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 careful study of the specifics grinding discs for a grinder on wood, you can proceed to the search suitable models, which 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:

1. circle diameter.
2. depth of cut in wood.
3. 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.

1. It is necessary to choose rounded cutouts that are made strictly towards the shaft.
2. Optimal Thickness disk is 2 mm.
3. The depth of the cuts made sometimes reaches 20 millimeters.
4. 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 activity, but even an inexperienced worker can do sanding an array. The main thing is that he has the required equipment at his disposal. Enough to deal with basic principles forthcoming work, and everything will be successful.

In most cases, peeling involves petal discs. 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. His work zone may have a small amount 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 whole flap discs, however low price characterizes a short service life. In any case, universal sticky models are effective in processing and grinding a wide variety of 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 peeling nozzles.

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 to solve 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.
