Power Tools 32mm Electric Rotary Hammer Heavy Duty

Electric hammer is a widely used electric tool. On the basis of the electric drill, the electric hammer is to add a piston with a crankshaft and connecting rod driven by the motor to compress air in a cylinder to make the air pressure in the cylinder change periodically. The changed air pressure drives the hammer in the cylinder to hit the top of the drill bit to and fro, which is equivalent to hitting the drill bit with a hammer. It is named electric hammer.

As the drill bit of the electric hammer rotates, it also produces rapid reciprocating movement (frequent impact) along the direction of the electric drill rod, so it can quickly drill holes on brittle cement concrete, stone and other materials. High grade electric hammers can use the change-over switch to make the drill bit of the electric hammer in different working states, that is, only rotating without impact, only impacting without rotation, both impacting and rotating.
