A grinder is a tool that is used for grinding, cutting and cleaning hard materials, such as metal, stone and concrete. With it, you can remove paint, polish, and also make strobes in the walls. However, these works are not a complete list of what the described tool is capable of.
How to choose a grinder by disk size
Work with a grinder will be effective only if you manage to pick up a tool with the right disc. Its diameter can be equal to the limit of 115 to 230 millimeters. When buying equipment exclusively for cutting material, the master should know that not all the working part of the disk will be involved. The part that acts as the body of the device will be exposed. Thus, if the casing of the angle grinder is 55 millimeters, then the disk, whose diameter is 115 millimeters, will be used less than half, namely 30 centimeters. Among other things, the disks grind during operation, especially when it comes to cutting metal. When purchasing a tool for solving domestic needs, it is best to prefer equipment whose disc has a diameter in the range of 115 to 150 millimeters.

Choosing a power angle grinder
In order not to have to acquire an anchor for the grinder during operation, it is necessary to choose the right power, which can vary from 0.5 to 2.5 kW. If you have to perform work of medium complexity, which will not take much time, you can get by with a model whose power is 900 watts. Whereas for more serious tasks it is preferable to use a more impressive power, which is 1500 watts. The master must remember that with an increase in power, the device will be able to work stably under an impressive load. If we are talking about an angle grinder, the diameter of which will be 230 millimeters, then its power starts from an indicator of 2 kW. If the grinder, the disk diameter of which is 115 millimeters, is purchased to perform complex work, for example, to clean the seams that are obtained after welding using heavy and abrasive wheels, the power of the equipment should not be lower than 1 kW. Thus, choosing the power of the device, you must take into account the complexity and duration of work, as well as the size of the circle and the weight of the unit.
Tool selection by weight
If you will choose an angle grinder, then the grinder regulator circuit should be considered. Perhaps this will allow you to make the right choice.

Whereas a 1 kW grinder has a mass within 2.3 kilograms. If we are talking about a powerful device, for example, 1.5 kW, then the mass will be increased to 3.5 kilograms. Although it is possible to purchase an anchor for a grinder on the market of component materials today, it is best to use the tool as carefully as possible to eliminate this need. After all, the additional expenses can be very impressive, especially for expensive models, the components for which are also impressive.
