  • Cutting tool and method of reducing the width of wear mark on a cutting tool
    Patent number: 7431747
    Abstract: The invention relates to a cutting tool made of ceramics, cermet or cemented carbide and including a rake face, a flank face and a cutting edge at the intersection of rake face and flank face, as well as a multi-layered wear resisting coating including a layer which is made of aluminum oxide and deposited on a hard material layer, in which for avoiding an increase in the width of wear mark, with simultaneous retention of the resistance to cratering of the rake face, the aluminum oxide layer of the coating is removed on the flank face and the underlying hard material layer is exposed at least in portions. The aluminum oxide layer of the coating is removed on the flank face preferably by means of laser beam treatment.
