Select a KEO countersink based on the screw head angle (typically 90° for flat-head screws), material type, and hole size. Match the body diameter to the screw head size and ensure the shank fits your tool holder. For hard materials, choose HSS; for softer materials, consider carbide. Always test on scrap material first.
