Abstract

Es wird ein Bohrer (1) zur zerspanenden Bearbeitung von Werkstücken mit geometrisch definierten Schneidkanten aufweisenden Vollbohrschneiden und Führungsfasen vorgeschlagen. Er zeichnet sich dadurch aus, dass vier Schneiden (11, 11'; 13, 13') und vier den Schneiden zugeordnete Führungsfasen (23, 23', 33, 33') vorgesehen sind, dass die Schneiden paarweise einander so zugeordnet sind, dass ein erstes Paar als Vollbohrschneiden (11, 11') und ein zweites Paar als Aufbohrschneiden (13, 13') ausgebildet sind.
