PVD coated TiCN and fi ne 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.
Grade Description
Coated carbide, PVD two-layer coating over fi ne-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.
Coating
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.

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.

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.
