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 can also drill steel and concrete, but the results are poor and the hammer is not the same. It is the use of motor driven, the bottom two sets of gear structure, a realization of it drill, and another one is to drive the piston, a hydraulic engine stroke, resulting in a strong impact force, along with the drilling results. Compared to the impact of drilling force, there is a hammer and hammer each place name is not the same, in some places that means the electric hammer drill. Finally is to choose and choose the hammer and hammer of that kind of, don't choose dual-use, easy bad dual-use. And when you buy an impact drill, don't buy the kind of drill holder. Buy that kind of impact drill bit.
