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 screw head type and the body diameter to your hole size. For hard materials like steel, choose carbide; for softer materials, high-speed steel may suffice. Always verify the flute count for chip evacuation needs.
