Impact Drill Principle

The principle of operation of the electric drill is the electromagnetic rotary or electromagnetic reciprocating small-capacitary motor motor motor rotor to do magnetic field cutting to do the operation, drive the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object, better piercing the object. The impact mechanism of the impact drill has two kinds of canine-tooth and ball-type. Ball-type impact drill consists of moving disk, fixed disk, steel ball, etc. The dynamic disk is connected to the spindle by thread and has 12 steel balls, and the fixed plate is fixed to the enclosure with pins, and with 4 steel balls, under the thrust action, 12 steel balls roll along 4 steel balls, so that the carbide drill bits produce a rotating impact motion, can drill holes in brittle materials such as bricks, blocks, concrete, etc. Off-overhead nails, so that the fixed disk with the moving disk to turn, do not produce shocks, can be used as ordinary electric drill.
