For a #8 xxxx , you typically need a countersink bit designed for #8 screws. Amana makes countersink bits specifically labeled for xxxx sizes; look for an Amana countersink bit marked for #8 (such as the Amana 55229 and the 55240). This ensures the pilot hole and countersink are properly sized for the xxxx head.
