A KEO 110° single-flute countersink creates a conical recess for flathead screws in metalworking. The 110° angle suits metric and aerospace fasteners. Its TiN-coated cobalt body resists heat and wear, making it ideal for hardened steels and stainless steel in machining and fabrication.

The KEO 55457-TiN is a 110° single-flute countersink with a 1 1/2 in body diameter and a 3/4 in shank. It is made from TiN-coated cobalt for durability. This fast-cutting design reduces chatter and produces clean, burr-free holes in ferrous materials.
