To select the right KEO countersink, match the angle (e.g., 120°) to your fastener's head angle, choose the body diameter (e.g., 1/2 in) to suit hole size, and pick flute count based on finish needs—six flutes for smoother results. High-speed steel works for general metalworking. Consult KEO's catalog for material-specific guidance.
