Cross-brand grade equivalence · brand-neutral
Kennametal KCM25B equivalents
How to read this page. These matches are compiled from grade comparison charts the manufacturers publish themselves, cross-checked against each other. A match means two grades are placed at the same ISO 513 application position, which is where the maker says the grade belongs. It does not mean the grades are interchangeable: substrate, cobalt content, coating and edge preparation still differ, and so will tool life and the cutting data you should start from. Validate any swap on a sample part before you change production. Something wrong on this page, or a grade you want removed? research@cuttingtoolsai.eu.
Kennametal KCM25B sits at ISO 513 application classes M15, M20 — stainless steel. 4 grades from other manufacturers cover that same full range and are confirmed by two or more manufacturer charts.
Grades placed at the same full ISO range
4 grades from other makers cover every one of KCM25B's application classes, not merely one of them, and are confirmed by two or more manufacturer charts. The 3 best-evidenced are shown; the rest are listed below. A grade that covers only part of the range is not listed as an equivalent here.
| Grade | Shared ISO classes | Evidence | Why it placed here |
|---|---|---|---|
| Walter WSM20S | M15, M20 | 3 sources | Confirmed by 3 manufacturer charts; covers both ISO classes of your grade (M15, M20); no published property data on file for one or both grades, so this rests on the ISO class alone. |
| Sandvik GC2220 | M15, M20 | 2 sources | Confirmed by 2 manufacturer charts; covers both ISO classes of your grade (M15, M20); no published property data on file for one or both grades, so this rests on the ISO class alone. |
| Seco CP500 | M15, M20 | 2 sources | Confirmed by 2 manufacturer charts; covers both ISO classes of your grade (M15, M20); no published property data on file for one or both grades, so this rests on the ISO class alone. |
Not verified: single-source candidates
These share an application class with Kennametal KCM25B but are named in one catalogue only, or cover less than half of its range. They are listed so you can check them yourself. They are not a recommendation and must not be used as a substitution without your own trial.
| Grade | Shared ISO classes | Evidence | Why it placed here |
|---|---|---|---|
| MOLDINO IP100S | M15, M20 | 1 source | Seen in one catalogue only; covers both ISO classes of your grade (M15, M20); no published property data on file for one or both grades, so this rests on the ISO class alone. |
What this does and does not tell you
An ISO 513 application class says which material group and which range of operations a grade is built for. Two grades sharing a class are built for the same job. They are not identical: substrate grain, cobalt content, coating and edge preparation still differ, and so will tool life and the cutting data you should start from. Treat a match here as the shortlist for your own trial, not as a drop-in replacement.
Everything above is derived from the makers' own published application data. Nothing is inferred from price, availability or popularity, and no manufacturer pays to appear here.
Kennametal KCM25B plus up to two grades you run next to it, worked through in one document: every cross-brand match with the number of manufacturer charts behind it, single-source candidates kept apart, where your grades overlap so the list can be shortened, and a validation plan. Emailed to you, usually within the hour. No account needed.
