Dimensions (Inch)--- IC (Size)=.250 (1/4) Thickness=.094 (3/32) Radius=.016 (1/64) Hole=.110 Relief Angle=7 Deg
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
MK2K--- Sturdy uncoated grade for turning grey cast iron and titanium alloys at medium speeds and feeds, especially under unfavorable conditions with heavy interruptions. This grade is a consistent grade for turning brass, aluminum, plastics, and wood.
MP4K--- General purpose uncoated durable steel cutting grade. For use in alloy steels and stainless steels under extremely difficult conditions such as heavy interrupted cuts or very low speeds with large chip section.
