Why is the electric hammer drill chuck and loose
It may be that the drill is not clamped or the chuck is abnormal. It is recommended to contact the service point.
Hammer principle is the driving mechanism to make rotation movement while the driven drill, hammer and reciprocating in a direction perpendicular to the rotor hammer motion. The hammer is driven by the transmission mechanism of reciprocating piston in a cylinder of compressed air, the air pressure change cycle reciprocating hammer drives the cylinder top blow brick in the cylinder, if we use a hammer percussion hammer named brick.
With a safety clutch of electric rotary hammer hammer with a pneumatic hammer drilling mechanism. Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, can open 6--100mm in concrete, brick, stone and other hard materials on the hole hammer in the above-mentioned materials on the opening of high efficiency, but it is not a hole in the metal.
