Frequently Asked Questions

What is a KEO 82° countersink used for?

The KEO 82° countersink with 3 flutes and AlTiN coated cobalt is designed for deburring and countersinking holes in metal, plastics, and composites. Its 82° angle suits standard flat-head screws, while the AlTiN coating extends tool life in abrasive materials.

What are the specifications of the KEO 917-000-890 countersink?

The KEO 917-000-890 is an 82°, 3-flute countersink with a 1/4 in body diameter, made from AlTiN coated cobalt. It is a general-purpose three-flute countersink, ideal for precision chamfering and deburring in industrial machining applications.

Where to buy KEO countersinks worldwide?
