KEO Countersink: 100°, 3 Flute, 1 1/2 in Body Dia, 3/4 in Shank

A KEO 100° countersink is used to create a conical recess in metal or plastic for flat-head screws or rivets. The 100° angle is common in aerospace and sheet-metal work. Its three-flute design provides smooth cutting and reduced chatter, making it suitable for general-purpose deburring and countersinking on drill presses or handheld tools.

The KEO 917-000-116 is a TiN-coated high-speed steel countersink with a 100° included angle, three flutes, a 1 1/2 in body diameter, and a 3/4 in shank. The TiN coating extends tool life and reduces friction when cutting steel, aluminum, or plastics. It is designed for general-purpose industrial use.

Select a KEO countersink by matching the body diameter to the screw head size and the shank diameter to your tool holder. For the 917-000-116, the 1 1/2 in body suits larger fasteners, while the 3/4 in shank fits standard drill chucks. Always verify the included angle (100°) matches your fastener's head angle for proper seating.
