How to select the right KEO countersink for your application?

Select a KEO countersink based on hole angle (e.g., 100°), material (carbide for hard metals), and body diameter matching your fastener. For general-purpose work, a three-flute design reduces vibration. Always match the countersink angle to the screw head angle for proper seating.
