Electric hammer is a kind of electric rotary hammer with safety clutch and pneumatic hammering mechanism. The working principle of electric hammer is piston motion. The compressed air impacts drills and you can use it to drill hole on the concrete material, bricks, stone and other hard materials. The advantage is high punching efficiency and less strength needed but it cannot be used to open a hole on the metal materials.
