P
Uncoated carbide. A very tough, ultra-fi ne grain unalloyed substrate. For M
general-purpose machining of most steels, stainless steels, high-temperature alloys, K
CM1 titanium, irons, and non-ferrous materials. Performs best at low speeds and
will handle interruptions and high feed rates. Use when C2, C3, or C25 N
fail due to chipping or breaking.
S
Grade HW-S25 P

M
A PVD-TiN-coated grade. Straight 9.5% Co substrate. Submicron grain. For
CG5 general-purpose machining of most steels, stainless steels, high-temperature alloys, K
titanium, irons, and non-ferrous materials. Performs best at low speeds
and will handle interruptions and high feed rates. N
