Grade High-Performance Taps Grades and Grade Descriptions WIDI GTD Coatings are designed for optimised tapping performance in specific materials. P Steel M Stainless Steel K Cast Iron N Non-Ferrous S High-Temp Alloys H Hardened Materials wear resistance toughness Coating Grade Description 05 10 15 20 25 30 35 40 45 WK12PG 4 PVD coated TiCN and fine grain carbide. Extraordinary wear resistance when tapping cast iron. High-temperature hardness allows long life at up to 4x faster speed than HSS-E-PM taps. K \ WN14PG A Coated carbide, PVD two-layer coating over fine-grain carbide. Coating consists of low friction CrC/C over wear-resistant TiN. CrC/C resists galling of non-ferrous materials to the tap. Provides superior performance for tapping cast aluminium and other non-ferrous materials. x4 N WH16PG i Coated carbide, PVD two-layer coating with heat-resistant TiAlN base layer and low-friction MoS2 top layer over carbide substrate. Use in hardened steel 55-63 HRC. V H GP6520 Coated HSS-E-PM, PVD heat- and wear-resistant high-vanadium cobalt powder metal HSS substrate coated with wear-resistant TiCN base layer. Use in steel, cast iron, and cast aluminium with silicon. j vA GM6515 X 7 / HSS-E-PM, PVD heat- and wear-resistant high-vanadium cobalt powder metal HSS substrate. Coating consists of low-friction CrC/C over wear-resistant TiN base layer. Use for tapping stainless steel and non-ferrous materials. M 4 N
