TNMG 160408 T9225 indexable turning insert (ISO TNMG 160408, 60°) – Tungaloy

The TNMG 160408 T9225 is an ISO‑standard indexable turning insert developed for medium to heavy steel turning, offering a combination of toughness and wear resistance for variable cutting conditions

• CVD-coated carbide for high wear resistance
• Universal T9225 grade for variable cutting
• 0.8 mm nose radius for consistent edge strength
• Double-sided chipbreaker, ISO TNMG 160408 compatible

Reliable cutting performance for demanding steel turning

The CVD‑coated carbide composition and the T9225 grade deliver a balance between hardness and toughness that is particularly suitable for medium‑to‑heavy steel machining. The CVD‑coated surface improves wear resistance under thermal and abrasive loads, which lengthens edge life and reduces unplanned tool changes. In practice, this means fewer interruptions on the shop floor, a steadier cycle time and improved process efficiency when handling variable engagement conditions or light interruptions in the cut. The combination of coating and substrate supports repeatable component quality and consistent tool life across batch sizes.

Straightforward integration and stable cutting geometry

Built to the ISO TNMG 160408 format, the insert ensures straightforward compatibility with matching holders when form, clearance angle, tolerance class, fixing method, size and thickness are observed. The triangular plate shape with a cylindrical centre hole and a plate thickness of 4.76 mm provides secure clamping and torsional stability in the toolholder. The 0.8 mm nose radius contributes to edge robustness and reliable surface finish without excessive cutting forces, while the double‑sided chipbreaker extends the number of available edges per insert. These characteristics reduce fixture checks and simplify inventory planning for toolrooms that require predictable mounting and repeatable results.

Application guidance and production benefits

Designed principally for external and internal turning, the insert is optimised for steel applications and performs well under interrupted cuts and changing engagement. Selecting the T9225 grade supports a wide material spectrum within steels and offers improved resilience where toughness is required. For operations seeking a pragmatic balance of running time and surface integrity, this insert helps lower overall machining costs through reduced tooling turnover and steady productivity. For specification checks or grade selection advice, Metav Werkzeuge can provide technical guidance to match the insert to the specific holder and machining strategy.

FAQ

What materials is this insert suitable for?
The TNMG 160408 T9225 indexable turning insert is primarily specified for steel machining; the T9225 grade and CVD coating are aimed at mid‑to‑heavy steel turning where toughness and wear resistance are required.

How does the 0.8 mm nose radius affect machining?
A 0.8 mm nose radius increases edge strength and helps achieve a consistent surface finish while keeping cutting forces at a practical level for medium‑duty turning operations with the TNMG 160408 geometry.

Is the insert reversible and how many cutting edges are available?
The triangular plate form and double‑sided chipbreaker mean the insert offers multiple usable edges; the exact number depends on mounting and indexing practice but this design extends service life compared with single‑edged configurations.

Which holders are compatible with this ISO designation?
Holders designed for ISO TNMG 160408 inserts with matching form, clearance angle, tolerance class, fixing and thickness will be compatible; verify the holder specifications against the TNMG160408 format before assembly.

What does the T9225 grade signify?
T9225 denotes a robust universal carbide grade optimised for variable engagement and slightly interrupted cuts; it is intended to provide a reliable compromise between flank wear resistance and fracture toughness in steel turning.
