Frequently Asked Questions

What is a KEO 90° single-flute countersink used for?

This KEO countersink creates clean 90° chamfers and countersinks in metal, plastic, and wood. Its single-flute design cuts fast with minimal chatter, ideal for deburring holes or preparing fastener seats in machining and fabrication applications.

What are the specifications of the KEO 919-002-974 countersink?

The KEO 919-002-974 is a 90° countersink with a 3/8 in body diameter, one flute, and TiN-coated carbide construction. The TiN coating reduces friction and extends tool life when cutting harder materials like steel or stainless steel.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Match the countersink angle (90° for standard flathead screws) and body diameter to your hole size. For harder materials, choose TiN-coated carbide like this KEO model. Single-flute designs work best for fast, chatter-free cutting in production environments.
