Sumitomo G10E: equivalent grades from other brands
uncoated carbide, milling grade. The makers' comparison tables place it at K10 (cast iron): 2 of 2 tables. The best-confirmed equivalents are Kennametal K115M, Iscar IC20, Tungaloy TH10, Kyocera KW10.
Note: table built by cross-checking the comparison tables published by Mitsubishi Materials (2025-2027 catalogue), Tungaloy (2023-2024) and Kyocera (2021). Each maker states its table is an estimate based on publications, not approved by the companies named; this one is not approved by them either. Equivalences are indicative: substrate, coating and geometry differ between brands. The catalogue of the grade you use is what counts. Grade names and trademarks belong to their owners.
