Frequently Asked Questions

What is a KEO 6-flute countersink used for?

A KEO 6-flute countersink creates smooth, chatter-free 90° chamfers and countersinks in metal. It is ideal for deburring holes and preparing fastener seats in machining, fabrication, and maintenance applications across industrial departments.

What are the specifications of the KEO 919-002-530 countersink?

The KEO 919-002-530 is a 90°, 6-flute countersink with a 3/8 in body diameter. It features an AlTiN coated cobalt construction for heat resistance and extended tool life. This smooth-finish design reduces vibration during operation.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Match the countersink angle (90° for standard fastener seats) and body diameter to your hole size. Choose flute count based on finish: 6-flute designs like KEO’s provide smoother cuts on harder materials. AlTiN coating suits high-speed or abrasive work.
