Where each table places it
| Kyocera (2021) | K20 |
| Mitsubishi (2025-27) | K10 · K20 · P10 · P20 |
The tables disagree: Mitsubishi (2025-27) also lists it for P (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.
