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.
