Electric hammer is a kind of electric drill, which is mainly used to drill holes on concrete, floor, brick wall and stone. It is specialized in drilling holes on walls, concrete and stone materials, as well as multifunctional electric hammers. It can be used instead of ordinary electric drills and electric picks if it is adjusted to an appropriate position and equipped with a proper drill bit.

The electric hammer has high efficiency, large hole diameter and long drilling depth. The principle of electric hammer is that while the transmission mechanism drives the drill to rotate, there is also a reciprocating hammering movement perpendicular to the rotary head. The electric hammer is a kind of hammer that drives the piston to and fro compress air in a cylinder by the transmission mechanism. The periodic change of air pressure in the cylinder drives the hammer in the cylinder to and fro hit the top of the brick, as if we hit the brick with a hammer, so it is called the electric hammer.
