KEO Countersink: 100°, 6 Flute, 1/4 in Body Dia

A KEO 100° countersink with six flutes is used to create a smooth, chamfered recess for flat-head screws in metalworking and machining applications. The 100° angle matches common aerospace and industrial fastener standards, while the six-flute design reduces chatter for a finer finish.

The KEO 919-000-412 is a 100°, six-flute countersink with a 1/4 in body diameter, made from high-speed steel. It is designed for smooth-finish countersinking in ferrous and non-ferrous materials. The six-flute geometry provides balanced cutting action and improved surface quality.
