Abstract
Derartige Werkzeuge werden als Diamant-Bohrkrone zum Bohren im felsigen Untergrund oder als Diamant-Sägeblatt zum Schneiden von Stein oder Asphalt eingesetzt.
Um bei hoher Schnittleistung die thermische Belastung der Schneidsegmente auf ein Mindestmaß zu reduzieren, wird ein einfach und kostengünstig herstellbares Diamant-Werkzeug vorgeschlagen, bei dem die Schnittflächen jedes Schneidsegments zur Richtung der Schnittbewegung um einen Winkel (α) von mehr als 15° und weniger als 40° derart geneigt sind, daß die Schnittflächen auf das zu schneidende Material auflaufen.
