The electric drill is only relying solely on the motor to drive the transmission gear to increase the strength of the drill bit rotation, so that the drill bit can be scraped in the metal, wood and other materials.

When the impact drill works, there are adjustment knobs at the drill chuck, adjustable drilling and impact drilling. However, the impact drill uses the gears on the inner shaft to perform the impact effect. The impact force is far less than that of the Electric Hammer. It can also drill reinforced concrete, but the effect is not good.

Hammer drill (electric hammer) is not the same, it is the use of the bottom motor to drive two sets of gear structure, one set to achieve it drill, and the other set is to drive the piston, just like the engine hydraulic stroke, producing a strong impact force, accompanied by drilling effect. Power can split stone gold.

The electric hammer is to allow the motor to drive the swinging gong to perform the bouncing movement so that the hoe has the effect of producing a gouge. The hydraulic Pump uses the gas pressure transmitted by the Air Compressor to drive the pump hammer in the electric kettle to move back and forth, thereby producing a hammering effect on the ground. However, the electric hammer only chiseles and its hammer does not rotate.

In short, the drill can only be drilled, and the impact drill can also have a slight hammering effect. A hammer drill can drill and a higher hammer, while an electric hammer can only hammer and cannot drill.
