SSEH 4100W-R10 Competitor's Product

Tool Diameter : ø10xR1 Cutting Conditions : vc= 32 m/min, f t = 0,018 mm/t doc = 20 mm, w oc =0,8m, Dry In Sumitomo Electric Hardmetal tests, the special coating with excellent adhesion resistance provided less cutting edge adhesion than the competitor's product and enabled fracturefree machining. The competitor's product suffered from edge adhesion leading to breakage.
