Tap Size Hollow-Core Cutters for Magnetic-Base Drills
These cutters are perfectly sized for cutting holes that will be tapped later. 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.
Arbor adapter for straight spindle fits a drill chuck or an R8 collet on a milling machine.
Arbor adapters for Morse taper spindle are for use on a drill press.
