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, plastic, and wood. Its six-flute design reduces vibration for a superior finish, ideal for aerospace, automotive, and general machining applications where precision and surface quality are critical.

How to select the right KEO countersink for my application?
