The difference between electric pick, electric hammer, impact drill, hand drill
Electric drill, impact drill (such as where the BOSCH GSB13 and GSB13RE difference): take RE a reversal and electronic transmission function, can control the machine is to reverse, and control the rotation speed of the machine speed, in addition to the normal drilling operations, can also screw nut job, can play the role of electric screwdriver. No RE can only drilling operations, no speed, positive and negative function, can not stretch the screws. The difference between GSB10RE and GSB13RE lies in the size of drilling holes and power, and the range of use of 13RE must be wider than that of 10RE. The corresponding machine is selected according to individual drilling diameter.Torch and impact drill difference: electric drill can only be suitable for drilling metal, wood, or screw operations, can not play mixed soil. Percussive drilling can drill holes in brick walls and ordinary concrete except metal and wood.The difference between drill and electric hammer impact drill drilling in metal, wood, the brick wall, ordinary concrete drilling operations, but if it is to strengthen the concrete pouring, the impact drilling would be more difficult, not because the impact drill wall (impact drill is on the two block impact gears impact friction impact however, the hammer is the impact of the movement of the piston cylinder, so the impact of hammer is much higher than that of ordinary drill) if you want to mix in mud drilling relatively hard, requiring high drilling efficiency, or long time in concrete drilling operations, or to select a hammer through the wall.
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.
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.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.
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.
