The teacher in the demonstration process, according to the methods and skills of practice summed up in simple formulas form explanation and demonstration, students often listen to understand, to do the normal operation demonstration, step by step action demonstration, slow motion model, so that the students easy to accept. Here the use of four formulas to guide the grinding process. Better effect.

Q: What's the difference between a twist drill and an impact drill?: Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force. Used of natural stones or concrete. When the impact drill works, the drill chuck is provided with an adjusting knob, which can be adjusted in two ways: an ordinary hand drill and an impact drill. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It is not suitable for drilling reinforced concrete.
