Abstract

Sintermetallgebundenes, abrasiv wirkendes Steinbearbeitungswerkzeug mit mehrschichtigem Aufbau und mit Diamant als Schneidstoff mit verbessertem Anschnittverhalten. Das Steinbearbeitungswerkzeug, beispielsweise ein Hohlbohrer, weist eine Anschnittzone (3) mit unterschiedlicher Zusammensetzung und erhöhtem Verschleiß gegenüber dem regulären Teil der Schneidelemente (1) im Bereich des Erstkontaktes mit dem Werkstück auf. Die Dicke der Anschnittzone ist auf den mittleren Korndurchmesser des verwendeten Schneidstoffes abgestimmt.
