■ Guide for TiCN coating • TiCN coating, applied through PVD (physical vapor deposition), features excellent abrasion and corrosion resistance properties, and improves mold–release performance. Hardness 3000HV– Coating thickness 2–5μm Color Blue–gray E The dimensions and tolerances shown in the drawings are the values after the product is coated. E The thickness of coating layer may be slightly inconsistent around the tip corners. ・ Coating made on the tip and shaft.
