Drill Chuck & Key

A drill chuck is a device that holds and tightens the drill bit in place during drilling operations. It is typically mounted on the spindle of a drill or similar power tool. The chuck consists of movable jaws that can be adjusted to grip the shank of the drill bit securely. This allows the drill bit to rotate with the spindle, enabling effective drilling. A chuck key is a tool used to tighten or loosen the jaws of the drill chuck. It usually has a T-shaped or L-shaped handle that fits into a corresponding socket on the chuck. By turning the key, the jaws of the chuck either move closer together to grip the drill bit or move apart to release it. The chuck key is essential for securing the drill bit in place and adjusting the chuck's grip to accommodate different sizes of drill bits.
