WNMG080412 Cross Reference
Equivalent WNMG080412 inserts across 7 brands — Sandvik, ISCAR, Kennametal, Walter, Tungaloy, Seco, Mitsubishi. Same ISO 1832 geometry class; grades, coatings and application windows differ by manufacturer. Treat equivalents as starting points and verify on a sample part: a cross-reference matches the geometry, not the process.
This is the roughing size of the family: the larger nose radius gives a stronger corner for heavier depths of cut and interrupted work, but raises radial force and the tendency to chatter on slender parts.

- W — shape
- trigon (80°)
- N — clearance angle
- relief angle 0° (negative insert, double-sided use possible)
- M — tolerance
- class M — molded, medium tolerance on inscribed circle and corner point (typically ±0.05–0.13 mm depending on size)
- G — type
- cylindrical fixing hole, chipbreaker on both faces (double-sided insert)
- 08 — cutting edge length / IC
- 8 mm nominal (inscribed circle / edge length class)
- 04 — thickness
- insert thickness 4.76 mm
- 12 — corner radius
- Rε = 1.2 mm nose radius
Type any maker's grade (e.g. GC4325, AC820P, T9215) to see grades other brands publish at the same ISO application position. VERIFIED = multi-source consensus; 2+ CHARTS = placement independently confirmed by two or more manufacturer charts; SINGLE-SOURCE = one chart only. Comparable at ISO position — not identical performance. Verify on a sample part.
