Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used to create a conical recess in metal or plastic for flush-mounting flat-head screws. Its 4-flute design provides smooth cutting and reduced chatter, making it ideal for precision deburring and countersinking in machining and fabrication applications.

What are the specifications of the KEO 60° countersink?

The KEO countersink has a 60° included angle, 4 flutes, 1 3/4 in body diameter, and 3/4 in shank diameter. It is made of high-speed steel (HSS) and carries the manufacturer part number 917-000-109. This tool is designed for use with drill presses or handheld drills.

Where to buy the KEO 60° countersink worldwide?
