Known as a Bulgarian tool - just an angle grinder
When some home masters who have a bench under their workbench and are quietly covered with dust Bulgar, ask why they need this machine, in return usually says: "And that was."And, you know, this approach once fully justifies itself. For example, you have heard about an angle grinder, but never really were interested in its cost or the principle of work, and suddenly it became necessary to patch concrete walls for wiring.
How will you work? A chisel? There are not any Bulgars. However, this business is fixable, we go to the store of construction tools. However, do not rush to the decision that you need the most powerful Bulgarian, let's remember what it is for you. So, you have not needed this tool for a long time, and now you need it. But then, perhaps, it will be postponed for another year.
As a Bulgarian, the tool is known to be highly specialized, designed for grinding, and therefore, apart from the stonework of concrete surfaces and metal polishing, you can adapt it only for cutting a stone.
Power tools bulgarian - why use only for the intended purpose?
Someone who needs a handmade Bulgarian for the house, in dreams already saws it not only metal pipes, but also almost whole logs. But let dreams remain those. Yes, discs for Bulgarians are sold, but they are intended mainly for stone, concrete and brick, there are also nozzles for metal, but it is better to saw this material with a special saw, but there can be no question of a tree.
The fact is that to rotate the grinding wheel 80 m / s - not the limit, the speed directly depends on the diameter of the nozzle, but low never happens. And now we remember that our ancestors extracted fire by friction, and it is already possible to predict the result of sawing wood - it will just catch fire. If you only grind the metal and make shallow grooves in the concrete, you can not be afraid of injuries, with the observance of safety measures, of course. However, it is only necessary to do sawing, and mindfulness should be doubled or even trebled.
A shaky hand or an error may cause serious injury, especially if your power tool is an industrial bullet. If you decide to cut a piece of pipe, make it the nearest to you "heel" nozzle, make incisions not very shallow, rotate the pipe as you see it, and do not cut between the supports, otherwise the pipe will converge on the cut, hitting .And the main rule - do not keep on the plane of rotation of the nozzle any part of the body, especially the head.
Big Bulgarians - lower disk rotation speed
Needless to say, beautiful Bulgarians are not always reliable. If you already have one foot on the doorstep and the goal is the store where these wonderful grinding machines are sold, let me give you some advice on the path. The choice you expect the most extensive, so immediately ask the consultant to show you only those that have the power you need, namely - for household needs up to 1 kW, for construction work, depending on the upcoming load up to 2.5 kW.By the way, the instrument with a power of 1.5 kW is a universal bulgarian, suitable for home and construction.
If you are offered a budget Bulgarian with a soft start, compare with expensive models, having necessarily installed a heavy disk, the difference can be quite appreciable.
Choose only domestic, German, French, Japanese and manufactured in the USA.Only a couple dozen models will remain. And what is important is the magnitude. A large Bulgarian( with two handles) is designed for a disc of the appropriate size, which is larger, the slower it rotates, and the greater the power required for overclocking.
For this it is necessary to pay attention to the presence of a self-closing system for brushes, since a tool that works with a certain amount of stress can burn out during a short-time power failure. It is also not out of place that, like a cutting-off machine, the bulgarian was equipped with a dust removal system. But it is appropriate only for large-scale construction and repair work, for domestic needs such a device will mean unnecessary waste of money.
