Abstract

Coated cemented carbide inserts, particularly useful in fine turning of super alloys, are disclosed. The inserts are characterized by a composition of a cemented carbide of WC, about 4.0 wt-% Co to about 7.0 wt-% Co, about 0.25 wt-% Cr to 0.50 wt-% Cr, and a coercivity (Hc) of about 28 kA/m to about 38 kA/m. The coating comprises a single (TiSi)N-layer, where x is between about 0.1 and about 0.25, with a crystal structure of NaCl type and a total thickness between about 0.5 μm and about 2.0 μm with a strong (200)-texture.
