TNMG160404 Cross Reference / ANSI TNMG 331
Equivalent TNMG160404 inserts across 7 brands — Sandvik, ISCAR, Kennametal, Walter, Tungaloy, Seco, Mitsubishi. In US (inch, ANSI B212.4) catalogs this same insert is listed as TNMG 331 — 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 finishing size of the family: the smaller nose radius lowers cutting force and lets you hold a finer surface finish at light depths of cut, at the cost of a weaker corner.

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 TNMG160404 mean?
TNMG160404 is an ISO 1832 insert designation. It decodes as: T — shape = triangular (60°); 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); 16 — cutting edge length / IC = 16 mm nominal (inscribed circle / edge length class); 04 — thickness = insert thickness 4.76 mm; 04 — corner radius = Rε = 0.4 mm nose radius.
What is TNMG160404 used for?
TNMG160404 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 TNMG160404 across brands?
TNMG160404 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 TNMG160404 a negative or positive insert?
TNMG160404 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.
