Frequently Asked Questions

What is a KEO 120° countersink used for?

A KEO 120° countersink creates a conical recess for flat-head screws in metalworking. Its 3-flute design reduces chatter for a smooth finish. KEO's TiN-coated cobalt construction suits general-purpose deburring and countersinking across machining, fabrication, and maintenance applications.

What are the specifications of the KEO 917-000-258 countersink?

The KEO 917-000-258 is a 120° countersink with 3 flutes, a 1/4 in body diameter, and TiN-coated cobalt material. It is a general-purpose three-flute countersink from KEO, designed for precision chamfering and deburring in industrial settings.

How to select the right KEO countersink for your application?

Select a KEO countersink based on screw head angle (120° for flat-head), material (TiN-coated cobalt for steel), and flute count (3-flute for reduced vibration). Match body diameter to your screw size. For deburring, ensure the tool's angle matches the chamfer required. Consult KEO's catalog for specific material recommendations.
