DCMT11T304 Cross Reference / ANSI DCMT 32.51
Equivalent DCMT11T304 inserts across 7 brands — Sandvik, ISCAR, Kennametal, Walter, Tungaloy, Seco, Mitsubishi. In US (inch, ANSI B212.4) catalogs this same insert is listed as DCMT 32.51 — identical geometry, different designation system. 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 DCMT11T304 mean?
DCMT11T304 is an ISO 1832 insert designation. It decodes as: D — shape = 55° rhombic (diamond); 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); T — type = fixing hole with countersink, chipbreaker on one face (single-sided positive insert); 11 — cutting edge length / IC = 11 mm nominal (inscribed circle / edge length class); T3 — thickness = insert thickness 3.97 mm; 04 — corner radius = Rε = 0.4 mm nose radius.
What is DCMT11T304 used for?
DCMT11T304 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 DCMT11T304 across brands?
DCMT11T304 is a shared ISO 1832 geometry, so Sandvik, ISCAR, Kennametal, Walter and other makers 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 DCMT11T304 a positive insert?
DCMT11T304 has positive clearance, so it is a positive, single-sided insert: lower cutting forces, suited to finishing, small parts and low-rigidity setups.
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.
