Product Description

KEO Anti-Vibration Zero-Flute Countersinks.

Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used to create a conical recess for flathead screws in metalworking and machining applications. Its zero-flute anti-vibration design reduces chatter, making it ideal for precision deburring and countersinking on CNC mills or drill presses.

What are the specifications of the KEO 60° countersink?

This KEO countersink has a 60° included angle, 0 flutes, 1/2 in body diameter, and 5/16 in shank. It features a TiN coated cobalt construction for heat resistance and extended tool life. The manufacturer part number is 919-000-190.
