==== Introduction ====

Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section.

In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the [[:chucks_and_collets|chuck]].
