KEO Countersink: 90°, 3 Flute, 1/2 in Body Dia

The KEO 917-000-023 is a 90°, 3-flute countersink used for deburring and chamfering holes in metal, plastic, and wood. It creates a clean 90-degree seat for flat-head screws. Common in automotive, aerospace, and general machining applications where precision countersinking is required.

The KEO 917-000-023 is a general-purpose three-flute countersink with a 90-degree included angle and a 1/2-inch body diameter. It is made from high-speed steel (HSS) and has a 1/4-inch shank. The three-flute design reduces chatter and provides a smooth finish.
