How to select the right KEO countersink for your application?

To select the right KEO countersink, match the angle (e.g., 82°) to your screw head, choose the body diameter (e.g., 1/2 in) for the hole size, and consider flute count for finish quality. Cobalt steel suits harder materials. For specific applications, consult KEO's technical data or contact 3G Electric for guidance.
