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

A KEO 90° 3-flute countersink is used to create a conical recess for flat-head screws in metalworking and machining. The 90° angle matches standard screw heads, while the three-flute design provides smooth cutting and reduced chatter. It is commonly applied in general-purpose deburring and countersinking on ferrous and non-ferrous materials.

The KEO 917-000-355 is a general-purpose three-flute countersink with a 90° included angle and a 1-inch body diameter. It is made from carbide for durability and wear resistance. The manufacturer part number is 917-000-355, and it is designed for precision countersinking in industrial machining applications.
