Drill bit

Drill bits are the cutters of drill tools. Bits are interchangeable, meaning that they can be removed from the end of the drill, either to replace a worn part or to change the size of the part.

Milling bits

Rather than being used in a drill, these bits are used in a milling machine, and are typically capable of horizontal as well as vertical motion while in a workpiece. The most common are endmills, which, once plunged into the workpiece, can move sideways to carve out complex shapes, with different shapes of the tip affecting the shape of the cut. A face mill can produce extremely smooth planes in a work piece, while a form mill can cut specialty shapes, often similar to a router bit. For more information on these bits, see milling machine and milling cutter.
