KEO Countersink: 90°, 0 Flute, 1 in Body Dia

A KEO zero-flute countersink creates clean, chatter-free 90° chamfers and countersinks in metal. Its anti-vibration design prevents chatter marks, making it ideal for precision machining, tool and die work, and aerospace applications where surface finish is critical.

The KEO 919-000-229 is a 90° zero-flute countersink with a 1-inch body diameter, made from cobalt steel. It is designed for anti-vibration performance, reducing chatter in hard materials. The cobalt construction provides heat resistance for extended tool life in demanding industrial applications.

Select a KEO countersink based on the required chamfer angle (90° for standard screw heads), body diameter matching your hole size, and material compatibility. Cobalt tools suit harder metals like stainless steel. Zero-flute designs minimize vibration, while fluted versions are better for softer materials.
