Class 1 vs 4 vs 6 belt-disc sanders
Compare belt-disc class ceilings against BeltDisc estimates, with verified VEVOR US product examples and an honest NO_MATCH path.
| Class | Belt × disc | Typical fit | Trade-off |
|---|---|---|---|
| 1 | 1 × 30 in belt · 5 in disc | Belt width need ≤ 1 in | Too narrow once you need a 4 in belt |
| 4 | 4 × 36 in belt · 6 in disc | Belt width need > 1 and ≤ 4 in | Still short if you need a 6 in belt |
| 6 | 6 × 48 in belt · 9 in disc | Belt width need > 4 and ≤ 6 in (ceiling) | Above 6 in → NO_MATCH; confirm live listing |
| NO_MATCH (above 6) | Not a class | Belt width need > 6 in | Do not force a 6 × 48 class — size up or change the plan |
