High Quality Rechargeable Rock Breaker Rotary Hammer Drills

The electric hammer is a kind of electric rotary hammer drill with safety clutch attached with a pneumatic hammering mechanism. The electric hammer uses the principle of piston motion to compress the gas to impact the drill bit. It does not require much effort to use hands. It can open 6-100mm holes in hard materials such as concrete, brick, stone, etc. The electric hammer has a high efficiency in opening holes in the above materials, but it cannot open holes in metal.

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.
