The difference between electric pick, electric hammer, impact drill, hand drill
Electric hand drill: a shell made of cast iron and capable of drilling 4mm holes in steel plates or planks. The utility model relates to a hand drill, which is a small drilling tool convenient for carrying, comprising a small motor, a control switch, a drill chuck and a drill bit.
Electric motor drives: let the swinging of the swing weight do bounce run, make pickaxe have gouge ground effect. The hydraulic pump pick is the gas pressure using the air compressor transmission pump is driven by the electric hammer in moving back and forth, resulting in pickax hit the ground effect, but only the Diangao chisel, it does not turn head.
Hammer (hammer): it is the bottom of motor drives 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 drilling results. Strength can split rocks into gold.
Percussion drill: when working, there are two ways of adjusting drill knob, adjustable drill and percussion drill. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, the impact force is far less than the hammer. It can also drill reinforced concrete, but it doesn't work.
The impact of drilling drill can also have a little effect, hammer hammer drill can drill and hammer, high electric hammer can not only do the drill, drill can drill small holes.
