Simple drill chuck key

2019-05-14

The drill chuck is one of the most commonly used tools for the drill press. The clamping is carried out by the small bevel gear of the key. The nut of the drill chuck is covered by a cone. The nut of the jaw is used to extend the jaws to loosen the drill bit. After the actual use for a period of time, the taper wheel on the chuck chuck and the small bevel gear of the key are worn to make the bit difficult to clamp. Therefore, when drilling, the chuck jaw and the bit handle slip and wear, reducing Drilling accuracy affects production efficiency.
