Frequently Asked Questions

What is a KEO 90° single-flute countersink used for?

A KEO 90° single-flute countersink creates a conical recess for flat-head screws in metal, plastic, or wood. Its 1-flute design provides fast, chatter-free cutting in production and maintenance applications across machining, fabrication, and assembly departments.

What are the specifications of the KEO 919-000-111 countersink?

The KEO 919-000-111 is a 90° countersink with 1 flute, 1/8 in body diameter, and 1/8 in shank diameter, made from high-speed steel. It is designed for fast cutting and deburring in precision workholding and tooling setups.

Where to buy KEO countersinks worldwide?
