materials at higher speeds. Excellent for machining most steels, stainless steels, cast
irons, non-ferrous materials, and super alloys under stable conditions. It also performs N
well machining hardened and short chipping materials.

M
An advanced PVD TiAlN-coated grade with a tough, ultra-fi ne-grain unalloyed
substrate. For general-purpose machining of most steels, stainless steels,
high-temp alloys, titanium, irons, and non-ferrous materials. Speeds may vary
from low to medium and will handle interruptions and high feed rates.
