Abstract
Abstract There is proposed a tool with a tool body and a wear resistant layer system, which layer system comprises at least one layer of MeX. Me comprises titanium and aluminum and X is nitrogen or carbon. The tool is a solid carbide end mill, a solid carbide ball nose mill or a cemented carbide gear cutting tool. Thereby, in the MeX layer the quotient QI as defined by the ratio of the diffraction intensity I(200) to I(111) assigned respectively to the (200) and (111) plains in the X ray diffraction of the material using the theta-2theta method is selected to be <=2. Further, the I(111) is at least twenty times larger than the intensity average noise value, both measured with a well-defined equipment and setting thereof.
