Frequently Asked Questions
What is a KEO 100° single-flute countersink used for?

How to select the right KEO countersink for your application?
Match the countersink angle to your fastener head — 100° for aerospace or 82° for standard flat-head screws. Choose body diameter larger than the screw head. Single-flute designs like KEO’s 919-000-173 cut aggressively; use slower speeds for harder materials to prevent chatter and extend tool life.
