How to select the right KEO countersink for your application?
To select the right KEO countersink, match the included angle (e.g., 100°) to your fastener's head angle, and choose flute count based on material: 6-flute designs like the 919-000-428 reduce chatter in harder metals. Body diameter should clear the hole size. For high-speed steel tools, use moderate speeds and coolant for best results.
