Cemented carbide insert coated with one or more layers of TiC, TiN, and/or Al2O3 or other materials
Coating thickness = 2.5 ‑ 13 m (0.0001 - 0.0005 in)
Coating applied by chemical vapor deposition or physical vapor deposition
Applications: cast irons and steels in turning and milling operations
Best used at high speeds where dynamic force and thermal shock are minimal
