High Quality Rotary Hammer Drill 1200W Electric Hammer 30mm

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.

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.
