Drill Chucks
Drill chucks can be of several types, but are typically three-jaw since three points on the circumference define a circle in two dimensions. A standard three-jaw and a multi-jaw chuck are shown in the figures below.

For a look at the mechanism of a three-jaw chuck, see the lathe section. The drill bit and chuck assembly can be mounted on a drill press, discussed in the drill press section.
