PVD Coated Carbide for Drilling
PVD Coated Carbide
KYOCERA’s PVD coated carbide for drilling is coated on a
very tough carbide substrate. Because of the low process
temperature compared with CVD, it features no erosion of
bending strength, less deterioration of coating and realizes
superior tool life and stable cutting.
