Frequently Asked Questions

What is a 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, producing a smoother finish in materials like steel and aluminum.

What are the specifications of the KEO 919-002-828 countersink?

This KEO countersink has a 90° included angle, 0 flutes, a 5/16 in body diameter, and an AlTiN coated cobalt construction. The AlTiN coating enhances wear resistance and heat tolerance for extended tool life in industrial machining.

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), body diameter matching the screw size, and coating for material compatibility. For hard metals, choose AlTiN-coated cobalt tools like the 919-002-828 for heat resistance.
