Patent number: 6224972Abstract: The present invention discloses an HSS tool with a PVD coating and with at least one cutting edge. The cutting edge has a radius of 15-25 &mgr;m and the carbides in the HSS are in contact with the coating. The present invention also relates to a method of making an HSS tool provided with a PVD coating with improved wear resistance. The improvement is obtained by subjecting the tool prior to the deposition of the coating to an electropolishing treatment such that a cutting edge radius of 15-25 &mgr;m is obtained and that the carbides in the HSS are revealed.Type: GrantFiled: June 7, 1999Date of Patent: May 1, 2001Assignee: Sandvik ABInventors: Anders Nordgren, Peter Littecke, Hans Johansson
