KEO 100° Anti-Vibration Zero-Flute Countersink

The KEO 100° countersink is designed for creating chamfered holes in metal, particularly for aerospace and automotive applications. Its zero-flute, anti-vibration design reduces chatter and improves surface finish. The TiN-coated cobalt construction provides heat resistance and extends tool life when machining hardened steels or stainless steel.

The KEO 919-000-249 is a 100° countersink with a 1 1/4 in body diameter, zero flutes, and TiN-coated cobalt material. It is part of KEO's anti-vibration series, designed for precision chamfering. The manufacturer part number is 919-000-249, and it is suitable for use with CNC or manual machines.
