Electric drills can be classified into 3 categories: electric hand drills, percussion drills, hammer drills.
1. Electric hand drill: the power is minimum, the application range is only limited to drilling wood and using the electric screwdriver, part of electric hand drills can be changed into special tools according to purposes, and the purposes and the types are more
2. Impact drill: the impact mechanism of the impact electric drill has two types of dog teeth and ball bearings. The ball type impact electric drill consists of a movable disc, a fixed disc, steel balls and the like. The movable disc is connected with the main shaft through threads and is provided with 12 steel balls; the fixed disk is fixed on the casing by using pins and is provided with 4 steel balls, and under the action of thrust, 12 steel balls roll along the 4 steel balls, so that the hard alloy drill bit generates rotary impact motion, and can drill holes on brittle materials such as bricks, building blocks, concrete and the like. The pin is disengaged, so that the fixed disk and the follow-up disk rotate together, no impact is generated, and the electric drill can be used as a common electric drill.
3. Hammer drill (electric hammer): holes can be drilled on various hard materials, and the application range is the widest.
Medical application:
(1) Dental: in the early 20 th century, wall-mounted three-bent-arm dental drills which rotate at 4000r/min and even 10000r/min still are widely used rope-wheel-driven three-bent-arm dental drills and derivatives thereof are shown.
(2) Otology department: the parent julius lemert of modern otology used electric drills for otology in new york first in 1938 to treat chronic ear diseases and reduce the incidence of facial nerve damage. However, the current electric drill is difficult to control and is very noisy. Modern electric drills and pneumatic drills greatly improve the rotating speed, strengthen the cutting capability, and enable an otologist to quickly finish accurate surgical dissection by using a quick cutting drill bit, a diamond drill bit and a flushing-sucking system, so that the surgical time is greatly shortened.
