Bulgarian, being a universal tool for a home builder or professional, used when performing many operations on cutting materials, grinders, peeling of various surfaces, etc.. Sooner or later, every owner of this tool asks questions: whether it is possible for a Bulgarian to work on wood, and what nozzles are needed for this?
Is a Bulgarian suitable for working with wood
The only operations with wood, which can be performed by an angle grinder (USHM) without fear it is grinding and peeling, and then, using special nozzles. Of course, you can saw wood, but is strictly prohibited! The internet is full of shocking photos, which testify, which leads to the use of an angle grinder as a cutting tool for wood.
The main arguments, which can be cited against the use of UHM for sawing, such.
- The design of this device is not intended for sawing wood.
- Because wood has a viscous and soft structure, then the saw blade can get stuck in it. Therefore, the Bulgarian woman often snatches it from her hands, and it flies in an unpredictable direction (in leg, by hand, in the abdomen, etc.), inflicting deep wounds or amputation of fingers on a person. There have even been cases of fatalities.
- When cutting wood, the pollen disk heats up very quickly, from which he begins to lose strength. At the slightest skew or excessive pressure, it can fly. Because the spindle speed of the USHM is large, because the tools fly away with shrapnel speed and go deep under human skin. The user is lucky, if the fragments do not fly into the head or eyes.
- Despite all the dangers of using saw blades with teeth, some USHM users ignore this fact and continue to install circular discs with large teeth or improved carbide solders. If when cutting wood it gets a hard knot or the remnant of a nail, then the tooth or solder breaks off, clings to the next tooth of the saw and is thrown out with the speed of a bullet. The consequences can only be guessed at.
- Ignoring all warnings, Bulgarian users install circular saws of larger diameter on the device, than a protective cover. This is the most dangerous option for using USHM.
Based on the above, it is possible to saw a tree angular grinder only at your own risk, and then, if it is a single or infrequent operation.
If you have to saw the tree constantly, it is better to buy a special machine for this purpose, or use an electric jigsaw. As a last resort, the Bulgarian can be used as a drive and make it a circular saw, fixing the device rigidly on the frame.
Existing circles for cutting wood
Despite the danger of using USHM for cutting wood, tool manufacturers still produce saw blades for it.
circular saws
The photo below shows a "dangerous" saw wheel for a Bulgarian woman, although its diameter corresponds to the protective casing of the grinder with the maximum working tool on 180 mm. There are saws with soldering 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 realized due to a small separation of teeth in different directions.
chain saws
Saw blade, is made with use of a chain from a chainsaw, reduces the risk of injury when jamming the tool. This nozzle is designed as follows, fixed on the internal disk (basis) the chain has a non-fixed fit.
In case of jamming of a chain in the processed material, the base continues to rotate, and the tool does not snatch from the hands.
These chain discs for the Bulgarian have many modifications, and with their help you can prune branches in the garden, and also use for rough cutting of thin boards.
In addition to cutting, chain drive can be used as a peeler, example, to remove the bark, as well as for cutting cups in log logs and modeling.
Saw with a small number of teeth
Also for the Bulgarian, to increase the safety of working with wood, tool manufacturers produce cutting discs with a small number of teeth.
Small diameter discs may have 3 tooth, and great - 4, as shown in the following photo.
These discs for the Bulgarian perfectly cut wood as along the fibers, and across. Besides, with the help of a saw wheel you can cut grooves, make different cuts and spikes in the workpiece. But when working with UHM should follow one rule: it is necessary to install on the Bulgarian a cutting disk of such diameter, for the use of which it is designed by the manufacturer, that is, do not exceed its size. You can put circles of smaller diameter.
Tungsten carbide discs
Tungsten carbide discs for angle grinders have recently appeared on the market and have made a kind of revolution in the field of woodworking.
This universal disc has no teeth. Instead of the last on a nozzle circle segments are located. The edged disc looks like a diamond wheel for cutting concrete. With the help of tungsten carbide wheel for Bulgarian you can very easily saw wood of any hardness and viscosity. Besides, he is not afraid of nails, screws and other metal inclusions, which may be in stock on its way.
This is the safest wood saw for an angle grinder.
Its price on the Internet is close 700 rub. But given the possible consequences of the use of circular beers, then it is a low price for security.
Nozzles for grinding of wood
For wood processing, except for cutting wheels, there are nozzles specially developed for installation on USHM, with which you can make peels, grinding, brushing and milling of wooden surfaces.
peeling nozzles
If you need to remove a layer of paint or other coating from a wooden surface, on the Bulgarian it is possible to establish a peeling nozzle. There are a large number of different attachments for peeling. They differ in shape, construction, and by type of work, which can be performed with this tool.
The photo below shows disc nozzles with spikes or crumbs, with which you can easily remove the top layer of wood, grind the end of the board, etc..
The next cutter, thanks to that, that the spikes on it are located on a flat plane, allows you to level different wooden surfaces. Example, if 2 the boards on the floor at the end joint are at different heights. With the help of this nozzle the defect is easily eliminated, and the boards are joined in one plane.
There are also peeling nozzles made of twisted wire. They can be made in the form of a metal cup with a wire inserted into it.
Or in the form of a disk with coils of wire clamped in its central part.
These korschets are used, if you need to quickly peel off old paint from a wooden surface or rust and paint from metal.
The following photo shows a brush with a wire of smaller diameter, and it is used for finer peeling work on wood and metal.
In addition to stripping, this corset is often used for brushing wood, that is, giving it the effect of aging. If this effect is to be applied to large surfaces, in the professional sphere, then for brushing it is better to use special hand machines with wide brushes.
Grinding and polishing nozzles
For grinding various surfaces, including wooden, on sale there is a special nozzle for USHM, consisting of a metal base, on which the emery grinding wheel is fixed by means of a velcro. The nozzle is screwed on the shaft of the Bulgarian and tightened with a wrench.
It is often equipped with an adapter for mounting in the chuck of a drill or drill.
The grinding wheel is not used for polishing surfaces. Instead, felt discs are installed on the nozzle, which are fastened with Velcro.
A sanding wheel is also often used to sand wooden surfaces. It is called from so, because it consists of many petals, fixed on its plane, made of sandpaper. The grain size of the latter can be chosen, based on the requirements for the treated surface. For rough grinding suitable sandpaper with a large grain, and for the final - on the contrary.
What is better to grind a tree - the Bulgarian or the grinder - depends on that, under which you are going to prepare a wooden surface. If under the application of ordinary paint, then you can use a grinding wheel. If under varnishing, then a grinding wheel, installed on the Bulgarian, cannot be used, as it will give small radial scratches on the surface of the wood, which will clearly appear after applying the varnish. In this case, a longitudinal belt grinder is used for grinding (sandpaper moves longitudinally) or vibrating, where the same emery wheels are used.
Safety measures when working with a Bulgarian on wood
If you still decide to use a Bulgarian as a tool for cutting wood, then some safety precautions should be remembered, which cannot be ignored.
- Before installing the tool on the angle grinder, it must be disconnected from the power supply.
- Never remove the protective cover from the UHM. This is the only barrier between the circular saw and your skin. In some cases, it will be able to protect your face from splinters, flying tool.
- It is a must when working with a Bulgarian woman on wood and not only wearing protective gloves.
- Do not use large and powerful UHMs for sawing wood. In case of jamming of the saw, you will not be able to hold the tool in your hands.
- Do not use saw blades with large teeth, as the probability of hooking them to hard wood fibers increases many times and, in accordance, the probability of snatching the tool from the hands increases.
- The UHM must have a speed regulator, which need to be reduced to a minimum. If there is no regulator in the device, it is better not to risk your health. As a last resort, the regulator can be made with your own hands, and install it in the extension socket.
- The Bulgarian should be kept strictly at right angles when sawing. At the slightest skew, the circular saw can break.
- Under no circumstances should the start button of the device be locked, because in an emergency you will not be able to stop the tool and minimize injuries.
