5 Function Rotary Rechargeable Hammer Drill Machine For Concrete 850W
The principle of the electric drill is the electromagnetic rotary or electromagnetic reciprocating small capacity motor's rotor doing magnetic field cutting and working, driving the operation device through the transmission mechanism to drive the gear to increase the power of the bit, so that the bit can be scraped on the surface of the object and better to penetrate the object.
The electric hammer is a widely used electric tool. The electric hammer is on the basis of the electric drill, adding a piston that has the crankshaft connecting rod by the motor, compressing the air in a cylinder, making the air pressure in the cylinder periodic change, the changing air pressure drives the hammer in the cylinder to strike the top of the drill bit, rather than hammering the drill with the hammer.
Electric hammer is a kind of electric drill, mainly used for drilling holes in concrete, floor, brick wall and stone. Professional in the wall, concrete, stone on the top of the hole, and multi-functional electric hammer, adjusted to the appropriate position with the appropriate bit can replace the common drill, the use of pickaxe.

architecture and Industry
It is widely used for reinforcement of building beams, boards, columns and walls, decoration, wall installation, stents, railings, billboards, air conditioning outdoor machines, guide rail, satellite receiver elevator, steel structure factory and so on.
As the electric drill is ventilated and dissipated, the dust will make the gear and the lubricating oil on the bearing (the sliding sleeve) mixed and suck up to aggravate the wear, especially the alternative use. In order to protect the rotary accuracy of electric drill and reduce the excessive clearance due to the wear of bearing (sliding sleeve), it is necessary to maintain clean internal and grease lubrication.
