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.

During the electric hammer operation, master the electric drill or the handle of the electric hammer. When drilling, first put the drill against the working surface of the special-shaped rivet, and then start it with moderate force to avoid shaking; If the speed drops sharply, the force shall be reduced to prevent the motor from overloading. It is prohibited to use a wooden shoulder to pressurize. When drilling, pay attention to avoid the reinforcement in the concrete.
