KEO Countersink: 100°, 1 Flute, 1 1/2 in Body Dia, 3/4 in Shank

A KEO 100° countersink is used to create a conical recess in a workpiece, typically for a flathead screw or bolt to sit flush with the surface. This 1-flute, 1 1/2 in body diameter, 3/4 in shank cobalt model is designed for fast cutting in hard materials like stainless steel.

The KEO 919-000-639 is a 100° single-flute countersink with a 1 1/2 in body diameter and a 3/4 in shank. It is made from cobalt steel for durability and heat resistance. The 1-flute design enables aggressive chip evacuation and faster cutting in industrial machining applications.
