Charging grinders for wood processing

The Bulgarian, being a versatile tool from a home master or professional, is used when performing a variety of operations on cutting materials, grinding, grinding various surfaces, etc. Sooner or later, each owner of this tool asks a question: can a grinder work on wood, and what tools are needed for this?

Is the grinder suitable for working with wood?

The only wood operations that can be performed with an angle grinder (angle grinder) without fear are grinding and grinding, and using special nozzles. Of course, it is possible to cut wood, but it is strictly forbidden! The Internet is full of shocking photographs, showing what the use of an angle grinder as a cutting tool for wood leads to.

The main arguments that can be brought against the use of angle grinders for sawing are as follows.

1. The design of this machine is not intended for sawing wood.
2. Since the wood has a viscous and soft structure, the saw blade can stick in it. As a result, the grinder is often pulls out of handand it flies in an unpredictable direction (in the leg, in the arms, in the stomach, etc.), causing deep wounds to the person or amputation of the fingers. Even fatal cases are witnessed.
3. When cutting wood very quickly saw blade heating, why he begins to lose strength. At the slightest bias or excessive pressure, it can fly apart. As the angle of the spindle of the angle grinder is large, the shards of the tool scatter with the speed of shrapnel and deeply penetrate the human skin. The user will be lucky if the fragments will not fly into the head or eyes.
4. Despite the danger of using saw blades with teethSome LBM users ignore this fact and continue to install circular discs with large teeth or advanced carbide tipped. If, when cutting wood, it gets a hard knot or the remainder of a nail, then the tooth or napayka breaks off, clings to the next tooth of the saw and is thrown out at the speed of a bullet. The consequences can only guess.
5. Ignoring all warnings, users of the Bulgarians install on the device a circular saw of a larger diameter than the protective cover. This is the most dangerous use of angle grinders.

Based on the foregoing, it is possible to cut a tree with an angle grinder only at your own peril and risk, and then, if this is a single or infrequent operation.

If you have to cut wood all the time, it is better to purchase a special machine for this purpose, or use jigsaw. In extreme cases, the grinder can be used as a drive and make a circular from it, fixing the apparatus rigidly on the frame.

What are the circles for cutting wood

Despite the danger of using angle grinders for cutting wood, tool makers still produce saw blades for it.

Circular Saws

The photo below shows the “dangerous” saw blade for the grinder, although its diameter corresponds to the protective casing of the grinder with a maximum working tool of 180 mm. There are saws with napayka and smaller diameter.

In the next photo you can see a less dangerous version of the circular saw. It provides protection against jamming, and it is implemented due to a small divorce of the teeth in different directions.

Chain saws

A saw blade made using chainsaw chains reduces the risk of injury when the tool is jammed. This nozzle is designed in such a way that the chain fixed on the internal disk (base) has no fixed fit.

In the event of a chain jamming in the material being processed, the base continues to rotate and the tool does not pull out of the hands.

These chains for the grinder have many modifications, and they can be used to trim branches in the garden, and also to be used for rough cutting of thin boards.

In addition to cutting, the chain disc can be used and as rough, for example, for removing the bark, as well as for cutting cups in logs of logs and modeling.

Saws with a small number of teeth

Also for the grinder, in order to increase the safety of working with wood, tool makers produce cutting discs with a small number of teeth.

Small-diameter discs can have 3 teeth, and a large one - 4, as shown in the following photo.

These disks for the grinder remarkably cut wood both along the fibers and across. In addition, using a saw blade, you can cut grooves, make various cuts and spikes in the workpiece. But when working with angle grinders, one rule should be followed: a cutting disc of such diameter should be installed on the grinder, the use of which is designed by the manufacturer, that is, should not exceed its dimensions. Circles of smaller diameter can be set.

Tungsten Carbide Discs

Tungsten carbide discs for an angle grinder went on sale not so long ago and made a kind of revolution in the field of wood processing.

This universal disk has no teeth. Instead of the last circumference of the nozzle are segments. The cutter disk looks like a diamond wheel for cutting concrete. With the help of a tungsten carbide wheel for the grinder, it is very easy to cut wood of any hardness and viscosity.In addition, he is not afraid of nails, screws and other metal inclusions that may be in the workpiece on his way.

This is the safest saw blade on wood for the angle grinder.

Its price on the Internet is about 700 rubles. But if we consider the possible consequences of using circular saws, then this is a low price for safety.

Nozzles for grinding wood

For wood processing, in addition to cutting wheels, there are nozzles specially designed for installation on angle grinders, with which you can perform abrading, grinding, brushing and milling wooden surfaces.

Peeling nozzles

If you want to remove a layer of paint or other coating from a wooden surface, you can install a stripping nozzle on the grinder. On sale there are a large number of different nozzles for roughing work. They differ in shape, design, and type of work that can be performed with this tool.

Below the photo shows disc nozzles spiked or crumb, with which you can easily remove the top layer of wood, grind the end of the board, etc.

The next cutter, due to the fact that the spikes on it are located on a flat plane, allows to level various wooden surfaces. For example, if 2 boards on the floor at the end of the joint are at different heights. With this nozzle, the defect is easily eliminated, and the boards are joined in the same plane.

There are also stripping nozzles. from twisted wire. They can be made in the form of a metal cup with wire inserted into it.

Or in the form of a disk with coils of wire clamped in its central part.

These brushes are used if you need to quickly strip off old paint from a wooden surface or rust and paint from metal.

The following photo shows a brush with a smaller wire diameter, and it is used for thinner roughing work on wood and metal.

In addition to stripping, this wrist is often used. for brushing wood, that is, giving it the effect of aging. If this effect needs to be applied on large surfaces, in the professional sphere, then for brushing it is better to use special hand-held machines with wide brushes.

Grinding and polishing tips

For grinding various surfaces, including wood, there is a special nozzle for angle grinders for sale,consisting of a metal base, which is fastened with velcro emery grinding wheel. The nozzle is screwed onto the shaft of the grinder and tightened with an open end wrench.

Often it is equipped with an adapter for fastening a drill or a drilling machine in the chuck.

The grinding wheel is not used for polishing surfaces. Instead, the nozzle is installed felt discswhich fasten with velcro.

Also used for sanding wooden surfaces flap emery circle. It is called so, because it consists of a set of petals, fixed on its plane, made of emery paper. The graininess of the latter can be selected based on the requirements for the treated surface. For rough grinding suitable sandpaper with coarse grain, and for fine - vice versa.

The better to grind a tree - grinder or grinder - depends on what you are going to prepare a wooden surface for.. If under drawing usual paint, then it is possible to use a grinding wheel. If under varnishing, the grinding wheel, installed on the grinder, cannot be used, since it will give small radial scratches on the surface of the wood, which will clearly appear after applying the varnish.In this case, for grinding use longitudinal belt sander (emery tape moves longitudinally) or vibration, where the same emery circles are used.

Security measures when working with grinders on wood

If you still decide to use the grinder as a tool for cutting wood, you should remember some safety measures that can not be ignored.

1. Before installing the tool on the grinder, it must be disconnected from the power supply.
2. Under no circumstances do not remove the protective cover with angle grinders. This is the only barrier between the circular saw and your skin. In some cases, it will be able to protect your face from scattering instrument fragments.
3. When working with grinders on wood and not only the use of protective gloves - a prerequisite.
4. Do not use large and powerful angle grinders for sawing wood. If the saw is jammed, you will not be able to hold the tool in your hand.
5. Do not use saw blades with large teeth, since the probability of their hooking on solid wood fibers increases many times and, consequently, the probability of pulling the tool from your hands increases.
6. LBM must have speed controllerthat need to be reduced to a minimum. If there is no regulator in the apparatus, then it is better not to risk your health. In extreme cases, the regulator can be made with your own hands, and install it into an extension socket.
7. The grinder should be kept strictly at right angles during sawing. From any slant, the circular saw can break.
8. In no case can not fix the start button of the device, because in an emergency you can not stop the tool and minimize injuries.
