KEO Countersink: 82°, 3 Flute, 1/2 in Body Dia

The KEO 82° three-flute countersink is designed for deburring and countersinking holes in metal, particularly steel and aluminum. Its 82° included angle matches standard flat-head screw angles, making it ideal for aerospace, automotive, and general machining applications where precise chamfering is required.

The KEO 917-000-889 is a general-purpose three-flute countersink with an 82° included angle, 1/2 in body diameter, and AlTiN-coated cobalt construction. The AlTiN coating enhances wear resistance and heat tolerance, extending tool life in ferrous and non-ferrous materials. It is designed for use in drill presses or CNC machines.

Select a KEO countersink based on the screw head angle (82° for flat-head screws), material type (AlTiN-coated cobalt for hard metals), and flute count (three flutes for balanced cutting). Match the body diameter to the hole size. For optimal results, use proper cutting speeds and lubrication as recommended for cobalt tools.
