Competitor's Endmill C (Slow Away Roughing Endmill) had high cutting resistance and had insert MEC hd better cutting performance / insert life comparing to Competitor's Endmill D, and the insert had
breakage, but MEC had no insert breakage and was still usable for further machining after ma- only small wear and was usable for further machining after used for machining of the same duration as
