WNMG080412 Cross Reference
Equivalent WNMG080412 inserts across 5 brands — Sandvik, ISCAR, Kennametal, Walter, Tungaloy. 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.
