WCMX050308 Cross Reference
Equivalent WCMX050308 inserts across 3 brands — Sandvik, ISCAR, Seco. 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.
A general-purpose nose radius: a balance of edge strength and finish that suits most first-choice turning before you tune up for finishing or down for roughing.

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.
