A chuck is a tool used to hold drill bits and other cutting tools in place. It is typically attached to the end of a drill or other power tool. Chucks come in a variety of sizes and types, and the type of chuck you need will depend on the size and type of drill bit or cutting tool you are using.
To take a chuck off a drill, you will need to loosen the chuck key. The chuck key is a small wrench that is used to tighten and loosen the chuck. Once the chuck key is loose, you can use your hand to unscrew the chuck from the drill.
