Insert grades Hardness (GPa) Insert grades A PVD coated carbide (Turning) PVD coated carbide (MEGACOAT / MEGACOAT NANO) Using a physical vapor deposition coating technology, generally because of the low processing temperature of PVD compared with CVD, PVD coated carbide features less deterioration and more bending strength. PVD coated carbide grades are coated on a very tough carbide substrate and suitable for turning.
