Recommended cutting data
The figures below are the manufacturers' published ranges, aggregated across the 5 variants listed on this page. The typical column is the median, which is where most shops end up running. Treat the full range as the envelope, not a target — start around 60–70% of it and work up.
| Workpiece material | Cutting speed vc (m/min) | Typical vc | Feed fn (mm/rev) | Depth of cut ap (mm) | Variants with data |
|---|---|---|---|---|---|
| Cast iron (K) | 150 – 450 | 150 – 450 | 0.03–0.3 | — | 1 of 5 |
| Hardened steel (H) | 90 – 180 | 105 – 155 | 0.03–0.3 | — | 4 of 5 |
To turn a cutting speed into a spindle speed for your actual diameter, use the cutting parameters calculator: n = vc × 1000 / (π × D).
Carbide grades available
5 variants of WNGA 080408 are stocked in these grades: PB30, PB60, PB90.
Across this range the grades specified most often are PB30, PB60, PB90. Within one brand's range, a higher middle digit usually means a tougher grade — better on interrupted cuts, slightly less wear resistant. See carbide grades explained for how to read the names.
