WNMG 06T312 — 80° trigon turning insert, 6 edges, Stainless steel. There are currently 2 variants in stock from HADSTO. Measured across the range: 9.53 mm inscribed circle, 3.97 mm thickness, 1.2 mm nose radius.
The designation encodes the geometry: the first letter is the shape (W), the following letter the clearance angle, then the tolerance class, then size, thickness and nose radius. If you want to check any of it, our ISO insert code decoder breaks the full string down character by character.

Recommended cutting data
The figures below are the manufacturers' published ranges, aggregated across the 2 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 |
|---|
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
2 variants of WNMG 06T312 are stocked in these grades: HS7120, HS7125.
Across this range the grades specified most often are HS7120, HS7125. 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.
Chipbreaker geometries
Chipbreakers stocked for WNMG 06T312: BM.
The chipbreaker sets the usable feed window far more than the depth of cut does. A roughing geometry run at finishing feed will not break the chip; a finishing geometry pushed into a roughing cut will chip. Match it to the feed you will actually run — chipbreaker selection guide.
