Grade Description
Coated HSS-E-PM, PVD heat- and wear-resistant high-vanadium cobalt powder metal
HSS substrate with high-hardness TiCN coating. Use when tapping heat-treated steel
44–55 HRC and cobalt- or nickel-based heat-resistant alloys.
S
H
Coated HSS-E-PM, PVD powder metal HSS-E substrate with two-layer coating.
TiN base layer and DLC top layer that resists galling of non-ferrous materials
to the tap. Use for tapping titanium. Not recommended for steel.
Coated HSS-E-PM, PVD powder metal HSS-E substrate with DLC coating.
Use for form tapping aluminium. Not recommended for steel. N
S
High-vanadium HSS-E substrate with a coating consists of low friction
CrC/C over wear-resistant TiN base layer. Use for tapping stainless steel
and non-ferrous materials. N
P
X8
Coated HSS-E substrate with TiCN PVD layer. Use in multiple applications, including
steel, stainless steel, ductile cast iron, and cast aluminium. WP42EG is more abrasion-
resistant than WU41EG.
