Where each table places it

Tungaloy (2023-24)M30 · S20 · S30

The tables disagree: Tungaloy (2023-24) also lists it for M (stainless steel); the other tables do not.

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.
