Each of them is accompanied by a brief description, technical characteristics, advantages and disadvantages.. It also provides guidance on tool selection.

How to choose an angle grinder "Bosch" and what to look for?

When choosing a grinder from the Bosch brand, you need to pay attention to the following features:

1. Power type.
   Bulgarians are network (work from voltage 220V) and battery.
   The former are used in rooms with access to the network, the latter are powered by 18V lithium-ion batteries.
   The latter function for a limited time and are relevant in cases where there are no outlets at the construction site / site.
   There are also gasoline and pneumatic models, but they require a separate discussion.
2. Disk size.
   The larger the diameter of the cutting wheel, the faster the device will work, reducing the time spent on repairs.
   The minimum size is 115 mm, the maximum allowable is 230 mm.
   The diameter is selected depending on the thickness of the material to be cut or sanded.
3. Power.
   This figure varies from 500 to 2700 W (or 0.5-2.7 kW).
   Accordingly, the greater the power of the grinder, the more efficiently it will cope with its duties.
   But the power consumption in this case will be higher (if the tool is powered by the network).
4. Number of handles.
   Angle grinders are single-handed and two-handed.
   The latter are more convenient to use, because they can be held with both hands during cutting or grinding work.
   Ideally, the main handle should have finger protection, as well as a rubberized coating (applies to both handles).
5. Rotational speed.
   This figure varies from 6000 to 15,000 rpm.
   Therefore, the higher it is, the faster and better the process of processing materials will take place.
6. Battery capacity.
   If the device is powered by a battery, the capacity of the latter should be within 2-4 Ah.
   And, the larger this figure, the longer the tool will be able to work.
