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.

The impact electric drill is an electric tool used for drilling holes on materials such as bricks, masonry blocks and light walls, which is mainly used for rotary cutting and has an impact mechanism that relies on the operator's thrust to produce impact force. Take off the overhead pin to make the fixed disc rotate with the moving disc without impact. It can be used as an ordinary electric drill.
