Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink is used to create a conical recess for flat-head screws or rivets in metal, wood, or plastic. Its single-flute cobalt design provides fast, chatter-free cutting in hard materials like stainless steel. Ideal for aerospace, automotive, and general machining applications.

What are the specifications of the KEO 919-000-643 countersink?

The KEO 919-000-643 is a 100° single-flute countersink with a 2-inch body diameter and a 3/4-inch shank. It is made from cobalt steel for durability and heat resistance. This tool is designed for fast cutting and clean finishes in industrial drilling operations.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your job?

Match the countersink angle (e.g., 100°) to your fastener head angle. Choose cobalt for hard metals or high-speed steel for softer materials. Ensure the body diameter exceeds the screw head size. KEO single-flute designs reduce vibration and improve finish in production runs.
