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): can drill holes in any material, the most widely used.
