Product Description

Cobalt steel counterbores provide more wear resistance at high speeds than high-speed steel counterbores and are suitable for machining hard materials. They make a flat-bottomed cavity at the top of an existing hole so that a bolt, nut, or other part is hidden beneath or sits flush with the top of the hole when installed into it. Also called solid pilot counterbores, these counterbores have a pilot that keeps the counterbore centered in the hole to ensure a level seat. The pilot is built-in and cannot be removed.
