KEO 100° Smooth-Finish Six-Flute Countersink

The KEO 100° 6-flute countersink is designed for creating smooth, burr-free 100° countersunk holes in metal, particularly in aerospace and precision machining. Its six-flute design and AlTiN-coated cobalt construction provide superior chip evacuation and extended tool life when working with hardened steels and stainless alloys.

The KEO 919-002-506 is a 100° countersink with six flutes, a 7/8 in body diameter, and an AlTiN coating on cobalt substrate. It is manufactured by KEO under MPN 919-002-506 and is part of their Smooth-Finish Six-Flute Countersinks product line, optimized for high-performance deburring and chamfering.
