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

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.
