Beschreibung
Zusammenfassung:	The present disclosure relates to a cutting tool of a cemented carbide substrate including WC and a binder phase having one or more of Co, Fe and Ni, wherein the cemented carbide also includes a finely dispersed eta phase of Me12C and/or Me6C carbides, where Me is one or more metals selected from W, Mo and the binder phase metals, wherein the substoichiometric carbon content in the cemented carbide is between −0.30 to −0.16 wt %. The disclosed cutting tool will achieve an improved resistance against comb cracks.
