SNMG120404 Cross Reference
Equivalent SNMG120404 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 finishing size of the family: the smaller nose radius lowers cutting force and lets you hold a finer surface finish at light depths of cut, at the cost of a weaker corner.

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.
