Core Bits Information
Core bits are cutting tools used to remove a cylindrically shaped piece of material, called a core. Core bits are similar in construction to hole saws, but differ in application. A hole saw is meant to create a large hole in a workpiece, while a core drill is designed to cut a hole and remove a core sample.
