Electric drill: It is a drilling machine that uses electricity to do power. It is a conventional product in power tools, and it is also the largest demand for power tools. Electric drills only have a rotary mode and are particularly suitable for drilling in materials that require little force, such as cork, metal, brick, tile, etc. The electric drill only relies on the motor to drive the transmission gear to increase the strength of the bit to rotate, so that the bit can do scraping through the form of metal, wood and other materials.
Percussion drill: relies on rotation and impact to work, can be used in natural stone or concrete. When the hammer drill is working, there is an adjustment knob at the drill chuck, which can be adjusted in two ways: ordinary hand electric drill and hammer drill. However, the impact drill uses the gears on the internal shaft to beat 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 the effect is not good. It is a basic power tool.
Electric hammer: is a type of electric drill, mainly used to drill holes in concrete, floors, brick walls and stone. Professional in the wall, concrete, stone above the hole, as well as multi-functional electric hammer, adjusted to the appropriate position with the appropriate drill can replace the ordinary drill, hammer use. The electric hammer uses the bottom motor to drive two sets of gear structure, one set to achieve it drilling, and the other set to drive the piston, like the engine hydraulic stroke, producing a strong impact force, accompanied by the drilling effect. Strength can divide stone and gold. Relying on rotation and hammering to work, the individual hammering force is very high and has a hammering frequency of 1,000 to 3,000 per minute, which can produce significant force. Compared to a percussion drill, an electric hammer requires minimal pressure to drill into hard materials such as stone and concrete, especially relatively hard concrete.
Electric Axe: It is to let the motor drive the swinging weight to run in the form of bouncing, so that the pick has the effect of chiseling the ground. The hydraulic pump pick uses the gas pressure transmitted by the air compressor to drive the pump hammer in the pick to rebound, thus producing the effect of the pick chiseling on the ground, but the pick is only chiseled, and its pick does not rotate.
