Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink with six flutes creates smooth, burr-free chamfers on holes for flat-head screws. It is commonly used in metalworking, aerospace, and automotive applications where a clean finish and precise 100° angle are required.

What are the specifications of the KEO 919-001-066 countersink?

The KEO 919-001-066 is a 100°, six-flute countersink with a 5/8 in body diameter, made from carbide. It is designed for smooth-finish countersinking in hard materials. The manufacturer part number is 919-001-066.

Where to buy KEO countersinks worldwide?
