KEO Countersink: 120°, 1 Flute, 1 in Body Dia

A KEO 120° countersink is used to create a conical recess for flat-head screws or deburr holes in metalworking. Its single-flute cobalt design provides fast, chatter-free cutting in hardened steels and alloys, common in aerospace, automotive, and general machining applications.

The KEO 919-000-683 is a 120° single-flute countersink with a 1-inch body diameter, made from cobalt steel. It is designed for fast cutting and long tool life in tough materials. The KEO brand is known for precision tooling in industrial machining.
