Select a KEO countersink based on hole size and material. The 90° angle is standard for flat-head screws. For harder metals, choose TiN-coated cobalt tools like the 919-000-620 for heat resistance. Match the shank diameter to your tool holder. Single-flute designs offer fast cutting; multi-flute options provide smoother finishes.
