What does a chuck do? A chuck is a clamp-like attachment that holds the drill bit or other tools used in drilling equipment. The end of the drill bit called the shank fits into the drill and is secured by the chuck. A chuck can be keyed, where the bit is positioned in the chuck with a special key, or keyless, where the chuck can be twisted when the drill bit is inside.

Angled Chucks are ideal for getting to those awkward places which would be impossible with a normal drill chuck.

Drill Chucks are attachments that are mostly universal across all drills. They are used to stabilise the rotating tool.
