Do not clamp portable grinders in a vise for grinding hand held work. Do not use any liquid coolants with portable grinders. Do not force wheels onto a grinder that is the wrong size or change mounting hole sizes. Do not tighten the mounting nut excessively. Do not put the grinder on the floor or working surface until the wheel has stopped turning.
Small grinders in the 4 to 5 inch range are helpful for DIY projects and simple tasks like removing brick mortar. Larger grinders can tackle tough jobs like cutting tile or stucco. Look for a motor in the 9 to 11 amp range for these projects. If your grinder is going to see a lot of work, pay attention to comfort and ergonomic design.
