High speed turning of Inconel 718 using PVD-coated PCBN tools [PDF]
CIRP Annals, 2016 Abstract Five different coatings and two PCBN grades were evaluated when high speed turning Inconel 718. Tool life was 40% higher when employing TiSiN coated over uncoated inserts at 200 m/min. When operating at 300–450 m/min however, coatings provided no appreciable benefit.

Tool Wear Mechanisms of pcBN tooling during High-Speed Machining of Gray Cast Iron
Procedia CIRP, 2018 The presence of graphite particles in gray cast iron commonly implies a good machinability, especially if compared to common steels. However, increasing industrial demands have resulted in a new interest for high-speed machining of these materials with higher performing tool materials than the traditionally used.
