Frequently Asked Questions

What is a KEO 82° countersink used for?

A KEO 82° countersink creates a conical recess for flat-head screws in metal, wood, or plastic. Its single-flute design and AlTiN-coated high-speed steel deliver fast, clean cuts in industrial machining, tool-and-die, and fabrication applications.

What are the specifications of the KEO 919-002-866 countersink?

The KEO 919-002-866 is an 82°, 1-flute countersink with a 1 1/4 in body diameter, made from AlTiN-coated high-speed steel. It is designed for fast cutting and is part of KEO's single-flute countersink line.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink size?

Select a KEO countersink with a body diameter matching your screw head size and an angle (e.g., 82°) that fits standard flat-head screws. For hard materials, choose AlTiN-coated high-speed steel for extended tool life and cleaner cuts.
