Abstract

The invention relates to a cutting tool comprising a cemented carbide substrate wherein the substrate comprises WC, eta phase in an amount of 1 to 10 vol% and between 3 and 20 wt% of a Co-based metal binder. The metal binder further comprises Al, Ni and possibly Cr so that: the weight ratio Ni/(Ni+Co) in the cemented carbide is between 0.1 and 0.5, the weight ratio Cr/(Cr+Ni+Co) in the cemented carbide is between 0 and 0.1 and the weight ratio AI/(AI+Cr+Ni+Co) in the cemented carbide is between 0.01 and 0.07. The composition gives the cemented carbide improved properties also when coated at higher temperatures.
