Abstract: The present invention relates to coated cemented carbide inserts, particularly useful in general turning of superalloys. The inserts are characterized by a composition of the cemented carbide of WC, 5.0-7.0 wt-% Co, 0.22-0.43 wt-% Cr and a coercivity (Hc) of 19-28 kA/m. The coating consists of a single (Ti x Al 1-x )N-layer, where x is between 0.25 and 0.50, with crystal structure of NaCl type, total thickness of between 3.0 and 5.0 µm, (200)-texture, and compressive residual strain of between 2.5*10 -3 and 5.0*10 -3 , possibly followed by an outermost TiN-layer.
