Electric drills can be divided into three categories: hand drills, impact drills, and hammer drills.
1. Hand drill: The power is the smallest. The scope of use is limited to drilling wood and being used as an electric screwdriver. It does not have much practical value.
2. Impact drill: The impact mechanism of the impact drill has two types: dog-shaped and ball-type. The ball type impact drill consists of a moving plate, a fixed plate, and a steel ball. The moving plate is connected to the main shaft through a thread and has 12 steel balls; the fixed plate is fixed on the casing by pins, and has 4 steel balls. Under the action of the thrust, 12 steel balls roll along 4 steel balls. The carbide drill bit produces a rotary impact motion and can drill holes in brittle materials such as bricks, blocks, and concrete. The overhead nail is removed, so that the fixed disk rotates together with the disk, and no impact is generated, and it can be used for ordinary electric drill.
3. Hammer drill (electric hammer): It can drill holes in any material and has the widest range of use.
The prices of these three kinds of electric drills are arranged from low to high, and the functions are also increased. The selection needs to be combined with their respective scopes and requirements.
