Any construction and repair work makes it necessary to cut, polish, and also clean the surface of the stone, metal or wood. Using a grinder or angle grinder (angle grinder) will allow you to cope with this task at a high level. Name «Bulgarian» It began to be applied to angle grinders back in the 1970s, when tools made in Bulgaria appeared. The tool works according to the following principle: thanks to the electric motor, the energy drives the brush or disc in motion. All that is needed is to skillfully direct the moment of rotation. Let’s try to determine, how to choose a grinder.
Selection recommendations
The choice of a huge number of tools depends on the tasks that will be solved with his participation. Therefore, grinders can be divided into professional and domestic. Their main difference is in price and design.
Household grinders are notable for their low cost and design with less endurance, since they are not designed for heavy loads. This is not to say that they are worse than professional ones, because for the house it simply does not make sense to pay for the purchase of an expensive tool if it is not often used.
If the work will be intense and lengthy, then you should think about acquiring a professional tool. Due to the fact that it is made of the highest quality materials, their reliability and durability are not in doubt. Every day, such a power tool is able to withstand enormous loads, however, its cost is much higher than household analogues.
Talk about power
At choosing a grinder It is important to consider the severity of the work: the larger it is, the more powerful tool you will need. Powerful products are more cost and weight.
The use of small-capacity grinders is used for cutting sheets up to 12 cm thick, medium-power angle grinders are designed for diameters up to 15 cm, and analogues with high power can easily cope with material up to 23 cm in thickness.
Grinders can be one-handed and two-handed. One-handed species, as a rule, are equipped with an additional handle, which can be easily rearranged, which ensures ease of use. The use of special vibration-absorbing handles increases usability. Some angle grinder manufacturers offer their customers not to shift the handle, but to turn the gearbox.
Pay attention to the drives
Circles can differ in the type of abrasive, the method of attachment, the grain size, as well as the inner and outer diameter of the disk. Circles are cutting and grinding.
The names of the discs eloquently inform about their purpose. The specification allows you to determine the type of material for which circles are intended. Marking «AND» reports that the nozzle is made of corundum and can be used for metal processing; for concrete and stone, purchase circles with the letter «FROM», made of silicon carbide. Diamond cutting wheels can be of type «granite», «asphalt» or «concrete». Having carefully studied the labeling of the disc, you can make the right choice.

Last parting word
Experts strongly advise you to purchase grinders only from reliable manufacturers who have worked out the final control and technology. Before buying a power tool, make a couple of test inclusions, this will determine the build quality of its power units. To do this, turn on the grinder and wait until its speed is maximum, then turn it off. Take a closer look at how she stops. Turnovers should decrease gradually and smoothly. Quality grinders will stop smoothly and there will be no infrequent separate knocks in their noise.
Pay attention to the gear housing. It is better that it be made of metal, optimally titanium or magnesium alloy. The housing of inexpensive household grinders is made of plastic, and conditionally professional – from an aluminum alloy. In professional models, the protective casing is made in such a way that it does not need to use any additional tool to turn it; to adjust it in household analogs, a wrench is indispensable. In a professional tool, the additional handle can have two to three positions.
Having reviewed features of choosing a grinder, we saw that this tool has such important indicators as power, diameter of the circles used, as well as other additional features that can greatly simplify life when using them.
