Coated cutting tool
The invention relates to a coated cutting tool comprising: i) a matrix comprising cubic boron nitride (cBN) and a binding phase comprising TiCyN1-y, where 0 < = y < = 1, where the binding phase contains the following impurities: e) aluminum, where the net strength ratio of Al to Ti in the matrix, measured by energy dispersive X-ray analysis (EDX), is less than 0.50; and/or f) tungsten, wherein the net strength ratio of W to Ti in the matrix is expressed as less than 0.035; and/or g) TiB2 (101) expressed as the ratio of the net peak height of the TiB2 (101) peak to the net peak height of the TiCN (200) peak as measured by XRD is less than 0.09; and/or h) an alpha-alumina (116), wherein the ratio of the net peak height of the alpha-alumina (116) peak to the net peak height of the TiCN (200) peak as measured by XRD is less than 0.06; ii) a coating deposited on the substrate, comprising at least one nitride consisting of a nitride of one or more elements belonging to groups 4, 5 or 6 of the periodic table of elements, or a nitride of Al and/or Si and one or more elements belonging to groups 4, 5 or 6 of the periodic table of elements. The invention also relates to a method of providing such a coated cutting tool.
