CNMG120408 T9215 — Tungaloy CNMG indexable insert for turning, CVD‑coated carbide

The CNMG120408 T9215 is an ISO‑format indexable turning insert in rhombic form, engineered for productive external and internal turning of medium‑grade steels.

• CVD‑coated carbide for high wear resistance
• Optimised for medium‑steel machining
• Double‑sided chipbreaker for flexible routing
• ISO CNMG 120408 form with 80° cutting geometry

High productivity and material advantage for turning operations

The CVD‑coated carbide composition of this insert, delivered in the T9215 specification, is developed for stable performance in medium‑steel applications. The CVD coating improves abrasion resistance under sustained cutting, while the substrate material maintains fracture safety during continuous or slightly interrupted cuts. This combination means longer intervals between indexings and a reduced per‑part tooling cost, supporting a more consistent production flow and fewer unplanned stoppages.

Predictable seating and stable clamping for accurate results

The insert’s ISO CNMG 120408 geometry, rhombic form and 80° cutting orientation deliver a familiar seating and force direction for standard CNMG holders. The 0° free angle, 4.76 mm thickness and 0.8 mm corner radius are critical for correct fit and cutting behaviour; compatibility with a holder depends on form, free angle, tolerance class, clamping method, size and thickness. The central cylindrical hole and the double‑sided chipbreaker enable reliable clamping and reversible use of the cutting edges, which enhances operational flexibility and reduces inventory variety without compromising stability.

Practical application, selection guidance and economic benefits

Designed primarily for external and internal turning, the insert performs best when matched with a chipbreaker and grade suited to the workpiece material and cutting conditions. The double‑sided chipbreaker supports effective chip control across a range of feeds, reducing rework and machine downtime. As an indexable insert, it simplifies tool‑change routines and keeps maintenance straightforward: worn edges are indexed or replaced, rather than regrinding entire tools. For workshops aiming for high throughput with consistent surface quality, this grade and geometry balance tool life, process reliability and productivity.

FAQ

What applications is this insert best suited for?
The CNMG120408 T9215 Tungaloy indexable insert is intended for external and internal turning of medium‑grade steels, offering a balance of wear resistance and toughness for continuous to lightly interrupted cuts.

How does the T9215 grade benefit production?
T9215 combines a CVD‑coated carbide substrate with properties that extend tool life under abrasive conditions while maintaining fracture safety, which supports higher productivity and fewer tool changes.

Is the insert compatible with standard CNMG holders?
Compatibility is determined by geometry and dimensions; the CNMG 120408 form, thickness (4.76 mm) and 0° free angle are standard, but holder match should be verified against form, tolerance class, clamping type, size and thickness.

Does the double‑sided chipbreaker allow reversible use?
Yes, the double‑sided chipbreaker provides flexibility in routing and indexing, permitting reversible use of the insert to extend service life and reduce inventory needs.

What should be considered when selecting a chipbreaker and grade?
Selection should be based on workpiece material, type of cut (continuous or interrupted) and machining stability; the T9215 grade is recommended as a first choice for medium‑steel applications.
