The countersunk head includes a frustoconical region having a first, smaller diameter in a shaft connection region and a second, larger diameter at a second end defining an edge area of the head. A plurality of radially extending ribs are located on the frustoconical region and extend from an area of the first, smaller diameter to a respective radially outer rib end spaced radially inwardly by a distance X from the edge area of the head. A respective cutting edge is located on each of the ribs.
