Abstract
A cutting tool includes a substrate of cemented carbide including hard constituents in a metallic binder. The hard constituents includes WC and the WC content in the cemented carbide is 80-96 wt %. The cemented carbide has a Ni content of 2.5-13 wt %, a weight ratio of Fe/Ni<1.5 and a weight ratio of Co/Ni<0.825. The cutting tool includes a rake face, a flank face and a cutting edge there between, wherein the hardness H is measured with Vickers indentation and the crack resistance W is the ratio of the load to the total crack lengths of the cracks in the corners of said Vickers indentation. The product of the hardness at the rake face H(rake) and the crack resistance at the rake face W(rake) for the cutting tool is H(rake)*W(rake)>2000 HV100*N/μm.
