Electric drills can be found in a variety of shapes and sizes, from a light household duty to the heavy-duty industrial grade hand drill and drill press. One variation of the electric drill is the hammer drill or rotary hammer. The hammer drill is a tool used for making holes in concrete and masonry.

Grinders are commonly used for shaping and finishing metal and other materials. Hand grinders are available in sizes ranging from those designed to do the intricate work of the die grinder to that of the 7-inch heavy-duty disc grinder.
