Counterboring—Enlarge the top of an existing hole to create a cylindrical-shaped opening with a flat bottom that acts as a seat for the head of a screw or wood plug.

These counterbores are oversized for use with screw holes in misaligned sheets or layers of material. All have a built-in pilot to maintain alignment in the hole. The body diameter and pilot diameter account for the 0.5 mm oversized diameter rating.
