Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 6-flute countersink used for?

The KEO 6-flute countersink is used for deburring and countersinking holes in metal, producing a smooth 82° chamfer. It is ideal for machining, fabrication, and maintenance applications where a clean finish is required on drilled holes.

What are the specifications of the KEO 919-000-749 countersink?

The KEO 919-000-749 is an 82°, 6-flute countersink with a 7/8 in body diameter, made from cobalt steel. It is designed for smooth-finish countersinking in hard materials and is suitable for industrial machining operations.

Where to buy KEO countersinks worldwide?
