M40K--- Universal multi-layered CVD Aluminum Oxide coated grade for use in a wide variety of stainless steel and steel materials. Used for rough to finish machining at medium to high speeds and feeds. Not usable in interrupted cuts.
M50K--- Universal multi-layered CVD Aluminum Oxide coated is a tough and wear resistant grade for use in light to rough turning of alloyed and unalloyed steels at medium cutting speeds even under slightly unfavorable conditions.
M60K--- Universal multi-layered CVD Aluminum Oxide coated grade excellent for grey cast iron and nodular irons including interrupted cuts also very good grade for hard steels, difficult to machine stainless steels, and titanium. Can turn high nickel ferrous materials and stellites and low to medium speeds and feeds.
