Abstract
A cutting tool insert is formed from a cemented carbide body and a coating particularly useful in medium-rough to rough turning of stainless-steels and superalloys. The cemented carbide body is formed from cemented carbide with a composition of 7.0-12.0 wt-% Co, 5.0-11.0 wt-% cubic carbide forming metals from group IVb, Vb and VIb of the periodic table, preferably Ti, Nb and Ta, and balance WC with a 10-30 μm essentially cubic carbide phase free and binder phase enriched surface zone. The coating includes an MTCVD Ti(C,N) as the first layer adjacent the body having a thickness of from >2.5 to 7.0 μm, on top of which an αAlOlayer is present, with a thickness of between 2.0 and 5.0 μm, and a total thickness of the coating of between 5.5 and 9.5 μm. The alumina layer has a (006) texture.
