Tungaloy AH730: equivalent grades from other brands
coated, milling grade. The makers' tables do not agree on where it belongs: Kyocera P30, Mitsubishi M30. Below are the equivalents table by table; check the Tungaloy catalogue before swapping it.
The tables disagree: Kyocera (2021) 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.
