DNMG150612 Cross Reference / ANSI DNMG 443
Equivalent DNMG150612 inserts across 7 brands — Sandvik, ISCAR, Kennametal, Walter, Tungaloy, Seco, Mitsubishi. In US (inch, ANSI B212.4) catalogs this same insert is listed as DNMG 443 — 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.
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.

ISO designation decoded — what DNMG150612 means
- D — shape
- 55° rhombic (diamond)
- N — clearance angle
- relief angle 0° (negative insert, double-sided use possible)
- M — tolerance
- class M — molded, medium tolerance on inscribed circle and corner point (typically ±0.05–0.13 mm depending on size)
- G — type
- cylindrical fixing hole, chipbreaker on both faces (double-sided insert)
- 15 — cutting edge length / IC
- 15 mm nominal (inscribed circle / edge length class)
- 06 — thickness
- insert thickness 6.35 mm
- 12 — corner radius
- Rε = 1.2 mm nose radius
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
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.
