Select a countersink based on the screw head angle (typically 90° or 82°), material of the workpiece, and desired finish. For ferrous metals, black oxide HSS like the CHICAGO-LATROBE 56758 reduces friction and extends tool life. Match the body diameter to the screw head size and ensure the flute count suits your chip evacuation needs.
