Keyless chuck for a cordless drill driver The type of chuck found on a cordless drill driver is known as a keyless chuck. It has 3 jaws which can be opened up to accept bits and closed to hold them firmly in place.

It’s called a ‘keyless’ chuck, because, unlike older models, it does not require a key to open and close the jaws. Instead, this is done by turning part of the chuck manually.
