Cross-brand grade equivalence · brand-neutral
Walter WKP35S: candidate alternatives
How to read this page. These candidates are compiled from grade comparison charts the manufacturers publish themselves, cross-checked against each other. A candidate means two grades are placed at the same ISO 513 application position, which is where the maker says the grade belongs. It is not a verified equivalent and does not mean the grades are interchangeable. Direct cross-brand equivalence and the independence of the sources could not be verified for these pairs: 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.
Walter WKP35S sits at ISO 513 application classes K20, P20 — cast iron, steel. 12 candidates from other manufacturers cover that same full range. They are candidate alternatives; none is a verified equivalent.
Candidates placed at the same full ISO range
12 candidates from other makers cover every one of WKP35S's application classes, not merely one of them, according to two or more manufacturer charts. The 5 best-evidenced are shown; the rest are listed below. A grade that covers only part of the range is not listed as a candidate here.
| Grade | Shared ISO classes | Evidence | Status and why it placed here |
|---|---|---|---|
| Mitsubishi VP15TF | K20, P20 | 4 sources | Candidate alternative, not a verified equivalent. Confirmed by 4 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
| Mitsubishi VP20RT | K20, P20 | 4 sources | Candidate alternative, not a verified equivalent. Confirmed by 4 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
| ISCAR IC908 | K20, P20 | 3 sources | Candidate alternative, not a verified equivalent. Confirmed by 3 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
| Mitsubishi UTi20T | K20, P20 | 3 sources | Candidate alternative, not a verified equivalent. Confirmed by 3 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
| Sumitomo AC1030U | K20, P20 | 3 sources | Candidate alternative, not a verified equivalent. Confirmed by 3 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
More candidates at the same ISO range
These also share the position (named in two or more manufacturer charts, at least half of the range), with less evidence than the candidates above. They are candidates, not verified equivalents.
| Grade | Shared ISO classes | Evidence | Status and why it placed here |
|---|---|---|---|
| Sumitomo AC530U | K20, P20 | 3 sources | Candidate alternative, not a verified equivalent. Confirmed by 3 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. |
| Sumitomo ACU2500 | K20, P20 | 3 sources | Candidate alternative, not a verified equivalent. Confirmed by 3 manufacturer charts; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. |
Weaker candidates: one chart or partial overlap
These share an application class with Walter WKP35S 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 | Status and why it placed here |
|---|---|---|---|
| ISCAR IC9150 | K20, P20 | 2 sources | Candidate alternative, not a verified equivalent. Seen in one catalogue only; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
| Kennametal KCU25 | K20, P20 | 2 sources | Candidate alternative, not a verified equivalent. Seen in one catalogue only; covers both ISO classes of your grade (K20, P20); no published property data on file for one or both grades, so this rests on the ISO class alone. Could not be verified: direct cross-brand equivalence, coating process (CVD/PVD) compatibility, source links, independence of the sources. |
| MOLDINO GM8020 | K20, P20 | 2 sources | Candidate alternative, not a verified equivalent. Seen in one catalogue only; covers both ISO classes of your grade (K20, P20); 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 candidate 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.
