A cutting tool for machining stainless steel including a tool nose geometry with several facets. The tool includes a nose comprising a leading edge which chips and removes stock from the edge surface, the leading edge bearing adjacent a calibration edge post which the bore is rotated to thereby calibrate the bore. The calibration edge or facet has a length equal to the feed per revolution. This same side has a cutting angle length equal to zero. A hollow cathode discharge method of TiCN coating with no more than three micron thickness is used. This coating method creates a high density of plasma vapor, does not contain micro particles, produces a very dense film which completely replicates the finish of the surface being coated, prevents buildup and increases tool performance. The leading facet preferably has a cutting edge angle with the tool direction of travel through the bore surface equal to 45°.
