The difference between electric drill, impact drill, hammer drill and electric pick

The electric drill only relies on the motor to drive the transmission gear to increase the force of the drill bit, so that the drill bit can be scraped in the form of scraping on metal, wood and other materials.

There are two ways of adjusting the drill, adjustable drill and impact drill at the drill chuck when working on the impact drill. However, the impact drill uses the gears on the inner shaft to jump against each other to achieve the impact effect, and the impact force is far less than the electric hammer. It can also drill reinforced concrete, but it does not work well.

The hammer drill (electric hammer) is different. It uses the bottom motor to drive two sets of gear structures, one set to achieve it, and the other set to drive the piston, like the engine hydraulic stroke, which produces a powerful impact force, accompanied by the drill effect. Strength can split the stone and divide the gold.

The electric shovel is a kind of bouncing operation that allows the motor to move and sway, so that the hoe can produce the effect of smashing the ground. The hydraulic pump 镐 uses the gas pressure transmitted by the air compressor to drive the pump hammer in the electric ram to bounce back and forth, thereby producing the effect of smashing the ground, but the electric hoe is only chiseled, and its hoe does not rotate.

All in all, the electric drill can only be drilled alone, and the impact drill can also have a slight hammering effect. Hammer drills can be drilled and hammered higher, while electric picks are only hammered and cannot be drilled.
