• Hand electric drilling machine: The power is the smallest and the application area is limited to electric drilling wood and as an electric screwdriver. Some electric hand electric drills can be converted into special tools with many uses and models depending on the intended purpose.

  
  

• Impact electric drill: The impact mechanism of impact electric drill has two types: dog tooth type and ball type. The ball impact electric drill consists of a movable plate, a fixed plate and a steel ball. The movable plate is threaded to the main shaft and has 12 steel balls; The fixed plate is fixed to the housing with pins and has 4-steel balls. Under the influence of thrust, the 12-steel balls roll along the 4-steel balls. The carbide electric drill bit produces a rotating impact movement that can drill holes in brittle materials such as bricks, blocks and concrete. Remove the pin so that the solid plate rotates with the movable plate without impact, which can be used as ordinary electric drill.

  
  

• Impact electric drill (electric hammer): It can drill holes into a variety of hard materials and has the widest range of applications.
