Dimenions (Inch)--- IC (Size)=.375 (3/8) Thickness=.188 (3/16) Radius=.047 (3/64) Hole=.173 Relief Angle= 5 Deg
M50E--- 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.
M60E--- 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.
MP4--- 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.
