Drill bit

A drill bit is a cutting tool used with a drill to remove material and create holes, typically with a circular cross-section. Drill bits are available in various sizes and shapes, designed to produce different types of holes in a wide range of materials. To function, drill bits are usually mounted in a drill, which provides the rotational force needed to cut into the workpiece.

The drill will grasp the upper end of a bit called the shank in the chuck.
