Compared with impact drills, electric hammers require minimal pressure to drill into hard materials, such as stone and concrete; Especially relatively hard concrete. The electric drill only has a rotation mode, which is especially suitable for drilling holes on materials requiring very little force, such as cork, metal, brick, ceramic tile, etc. The percussion drill works by rotation and impact. A single impact is very slight, but the impact frequency of 40000 times per minute can produce continuous force.
