Frequently Asked Questions

What is a KEO 110° countersink used for?

A KEO 110° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, ensuring a clean finish for assembly or deburring.

What are the specifications of the KEO 53381-TIN countersink?

The KEO 53381-TIN is a 110° single-flute countersink with a 3/8 in body diameter, made from TiN-coated high-speed steel. The TiN coating reduces friction and extends tool life. It is designed for fast cutting in industrial machining operations.
