The geometry of these cutters allows you to cut aligned holes in multiple sheets at one time. Use them with magnetic-base drills. You can also pair them with an arbor adapter (sold separately) when using a manual drill press or milling machine. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. They're also known as annular cutters.

Pilot pins align the cutter and eject the slug. They're also known as ejector pins.
