SNMG120412 Cross Reference
Equivalent SNMG120412 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.

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.
