Coatings provide high-speed
capability and are engineered
for fi nishing to light roughing.
• Reduce cycle times —
high speed and feed capability.
• Longer tool life — new multilayer
coating provides better wear resistance.

P
A premium, single-phase PVD TiN coating over a tough, specially formulated substrate
that performs well under extremely low to moderate speed conditions found on screw
machines. Ideal for carbon steels, alloy steels, most stainless steels, and many high-
temperature alloys.

P
A premium PVD-TiCN coated, shock-resistant carbide designed for low to moderate
speeds. Excellent resistance to welding and BUE, along with improved abrasion
resistance make this an ideal grade for austenitic stainless steel, low carbon steel,
and high-temperature alloys.
