KEO 90° Three-Flute Countersink, 1 in Body Dia, AlTiN Coated High Speed Steel

The KEO 90° 3-flute countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its 90° angle suits standard flat-head screws, while the three-flute design reduces chatter for a smooth finish. Common in automotive, aerospace, and general machining applications.

The KEO countersink model 917-000-939 has a 90° included angle, 3 flutes, and a 1-inch body diameter. It features an AlTiN (aluminum titanium nitride) coating on high-speed steel for extended tool life and heat resistance. It is a general-purpose three-flute countersink from KEO.

Select a KEO countersink based on hole angle and material. For standard flat-head screws, use a 90° tool. Choose flute count: 3-flute designs reduce vibration for cleaner cuts. AlTiN coating suits harder materials like steel. Match body diameter to your chuck capacity. Always use proper cutting speeds for high-speed steel.
