KEO Countersink: 120°, 1 Flute, 1 in Body Dia

The KEO 120° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

The KEO 919-000-057 is a 120° countersink with 1 flute and a 1-inch body diameter, made from high-speed steel. It is designed for fast cutting and produces a smooth finish. The single-flute geometry reduces vibration, and the 120° angle matches standard flat-head screw angles for precise seating.

Select a KEO countersink based on the screw head angle (e.g., 120° for flat-head screws), material (high-speed steel for general use), and body diameter matching the screw head size. For deburring, a single-flute design reduces chatter. Always match the countersink angle to the screw's included angle for proper seating.
