SCMT09T308 Cross Reference
Equivalent SCMT09T308 inserts across 6 brands — Sandvik, ISCAR, Kennametal, Walter, 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.
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.

- S — shape
- square (90°)
- C — clearance angle

- M — tolerance
- class M — molded, medium tolerance on inscribed circle and corner point (typically ±0.05–0.13 mm depending on size)
- T — type
- fixing hole with countersink, chipbreaker on one face (single-sided positive insert)
- 09 — cutting edge length / IC
- 9 mm nominal (inscribed circle / edge length class)

- Rε = 0.8 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.
