Frequently Asked Questions
What is a KEO 6-flute countersink used for?
A KEO 6-flute countersink is used to create a smooth, chamfered recess for flat-head screws in metalworking and machining applications. The six-flute design reduces chatter and produces a finer finish than standard countersinks, making it ideal for precision assembly and deburring operations.

How to select the right KEO countersink for your application?
Select a KEO countersink based on the screw head angle (typically 60° or 82°), material type, and desired finish. For steel or stainless steel, use high-speed steel tools like the 919-000-303. Match the body diameter to the screw head size. Six-flute designs provide smoother finishes than three-flute versions.
