Abstract
The present invention relates to a method of making a coated cutting tool comprising providing a substrate, depositing on said substrate a cathodic arc evaporation PVD coating of nitrides, oxides, borides, carbides, carbonitrides, carbooxynitrides, or combinations thereof wherein the coating during deposition is subjected to more than one ion etching step. Cutting tools made according to the present invention will exhibit an increased life time due to increased smoothness of the PVD coating which is due to a reduced number of surface defects.
