WK12PG PVD coated TiCN and fi ne grain carbide. Extraordinary wear resistance when tapping K
cast iron. High-temperature hardness allows long life at up to 4x faster speed
than HSS-E-PM taps.

WN14PG Coated carbide, PVD two-layer coating over fi ne-grain carbide. Coating consists N
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 aluminum
and other non-ferrous materials.

Grade WH16PG Coated carbide, PVD two-layer coating with heat-resistant TiAlN base layer
and low-friction MoS top layer over carbide substrate. Use in hardened steel
2
55–63 HRC.

GP6520 Coated HSS-E-PM, PVD heat- and wear-resistant high-vanadium cobalt powder K
metal HSS substrate coated with wear-resistant TiCN base layer. Use in steel,
cast iron, and cast aluminum with silicon.

M
GM6515 HSS-E-PM, PVD heat- and wear-resistant high-vanadium cobalt powder N
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.
