Hollow-Core Cutter Kits for Magnetic-Base Drills

Kits include five cutters, a pilot pin, and a hex key. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. For use with magnetic-base drills. They're also known as annular cutters. Pilot pins align the cutter and eject the slug. They're also known as ejector pins.
