Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is designed for creating 120-degree chamfered holes in metal, ideal for deburring and countersinking screw heads in industrial machining and fabrication. Its single-flute design provides fast, clean cutting in steel and other materials.

What are the specifications of the KEO 919-002-578 countersink?

The KEO 919-002-578 is a 120°, 1-flute countersink with a 1/2 in body diameter. It features an AlTiN coating on cobalt steel for heat resistance and extended tool life. This fast-cutting single-flute countersink is suitable for high-speed machining applications.

Where to buy KEO countersinks worldwide?
