CNMG 120404 T9215 – Indexable Insert for Turning, Tungaloy

The CNMG120404 T9215 indexable insert is an ISO‑standard turning insert engineered for medium steel machining, offering high wear resistance and fracture toughness for continuous to lightly interrupted cuts.

• ISO‑standard rhombic insert, 80° geometry
• CVD‑coated carbide grade T9215
• Dual‑sided chipbreaker, cylindrical hole
• High wear resistance for medium steel

Higher productivity through a tough, coated grade

The CVD‑coated T9215 carbide grade combines wear resistance with controlled toughness to maintain edge integrity in sustained production. This balance reduces unscheduled tool changes and supports more consistent cycle times, which improves overall line efficiency. The coating lowers friction at the cutting edge and helps to delay flank wear, so operators can expect stable cutting performance during continuous to slightly interrupted turning operations.

Predictable fit and safe clamping for reliable tool life

Compliance with the ISO‑standard CNMG geometry ensures compatibility with standard holders when form, relief angle, tolerance class, clamping method, size and thickness match. The CNMG120404 geometry (80° included angle) with a 0.4 mm radius and 4.76 mm thickness provides a stable seating area; the insert’s cylindrical hole supports secure fastening. These measurable attributes reduce setup variation and contribute to repeatable tool life and part quality.

Improved chip control and surface results

The chipbreaker design on both cutting faces controls chip formation and evacuation, reducing the risk of built‑up edge and erratic chip behaviour. As a result, the system delivers an improved surface finish and fewer interrupted passes for rework. For less experienced users, a chipbreaker shapes the swarf into shorter, manageable chips and protects the cutting edge, which in turn supports consistent component tolerances and lowers scrap rates.

Practical guidance for turning applications

Designed specifically for turning, the insert is suitable for both internal and external operations on medium steel. Select the matching chipbreaker and holder rigidity according to the workpiece and depth of cut; a stable machine setup and appropriate feed speeds are decisive for maximising the grade’s potential. For short interruptions in the cut, the grade’s fracture resistance preserves edge integrity; for heavily interrupted operations, a different geometry or cutter solution is recommended. Technical advisers are available to clarify holder compatibility or to recommend cutting parameters.

FAQ

Is this insert suitable for machining steel?
The CNMG120404 T9215 insert from Tungaloy is optimised for medium steel and combines wear resistance with fracture toughness to deliver reliable performance in continuous to lightly interrupted turning.

Which holders are compatible with this insert?
Holders designed for CNMG‑style inserts with matching form, relief angle, tolerance class and correct clamping fit are compatible; the cylindrical hole requires a corresponding fastener arrangement for secure seating.

What cutting conditions are recommended?
Best results are achieved under continuous to slight interrupted cuts with stable workholding; the T9215 grade supports productive cutting speeds while maintaining edge life—adjust feed and depth of cut according to component tolerances and holder rigidity.

Can the insert be indexed to use all cutting edges?
Yes, the insert is double‑sided with a chipbreaker on both faces, allowing indexing to extend usable cutting edges and improve cost efficiency.

What surface quality can be expected with this insert?
Thanks to the chip control provided by the chipbreaker and the CVD‑coated carbide, users can expect a consistent surface finish and repeatable dimensional results when machining medium steel with a stable setup.
