KEO Anti-Vibration Zero-Flute Countersinks.

Frequently Asked Questions

What is the KEO 90° countersink used for?

The KEO 90° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its zero-flute design reduces vibration and chatter, making it ideal for precision deburring and countersinking on ferrous and non-ferrous materials.

What are the specifications of the KEO 90° countersink?

The KEO countersink has a 90° included angle, 0 flutes, a 1/2 in body diameter, and a 5/16 in shank. It features a TiN-coated cobalt construction for wear resistance. The manufacturer part number is 919-000-224.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (typically 90° for flat-head screws), material compatibility (TiN-coated cobalt for hard metals), and shank size matching your tool holder. For vibration-prone operations, choose the zero-flute anti-vibration design to improve surface finish.
