Frequently Asked Questions

What is the KEO 917-000-833 countersink used for?

The KEO 917-000-833 is a 90°, 4-flute countersink used for deburring and chamfering holes in metal. Its AlTiN-coated cobalt construction suits high-speed machining on steel, stainless steel, and cast iron. Common in automotive, aerospace, and general manufacturing for creating clean, countersunk screw seats.

What are the specifications of the KEO 917-000-833 countersink?

The KEO 917-000-833 is a 90° included-angle, 4-flute machine countersink with a 1 1/4 in body diameter. It features AlTiN coating on cobalt steel for heat resistance and wear life. The manufacturer part number is 917-000-833, and it is designed for industrial CNC and manual applications.

Where to buy the KEO 917-000-833 countersink worldwide?
