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.

Cross-reference a grade at its ISO position
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 confirmed by two or more manufacturer-published charts; SINGLE-SOURCE = one chart only. Comparable at ISO position — not identical performance. Verify on a sample part.
Frequently asked questions
What does WCMX050308 mean?
WCMX050308 is an ISO 1832 insert designation. It decodes as: W — shape = trigon (80°); C — clearance angle = relief angle 7°; M — tolerance = class M — molded, medium tolerance on inscribed circle and corner point (typically ±0.05–0.13 mm depending on size); X — type = manufacturer-specific feature; 05 — cutting edge length / IC = 5 mm nominal (inscribed circle / edge length class); 03 — thickness = insert thickness 3.18 mm; 08 — corner radius = Rε = 0.8 mm nose radius.
What is WCMX050308 used for?
WCMX050308 is a turning insert. The brand-equivalents table on this page lists each maker's grade and its ISO application window (the P, M, K and similar ranges). Match the geometry first, then choose the grade for your material and operation, and verify on a sample part.
What is the equivalent of WCMX050308 across brands?
WCMX050308 is a shared ISO 1832 geometry, so Sandvik, ISCAR and Seco each offer it in their own grades and coatings. A cross-reference matches the geometry, not the process, so treat equivalents as starting points and verify on a sample part.
Is WCMX050308 a negative or positive insert?
WCMX050308 has 0° clearance, so it is a negative, usually double-sided insert run in a negative holder: strong and economical for general turning and roughing.
Does this cross-reference favour specific brands?
No. Comparable grades appear here only because manufacturer-published comparison charts place them at the same ISO application position. No manufacturer pays for placement, nothing on this page is sponsored, and CuttingToolsAI sells no tools and earns no commission. Placements backed by a single chart are flagged as such, and every comparison ends the same way: verify on a sample part before switching.
