CNMG 120404 T6215 ISO turning insert, CVD-coated carbide — Tungaloy

The CNMG 120404 T6215 is an ISO-standard turning insert engineered for stable to slightly interrupted turning operations, particularly suited to machining stainless steel.

• CVD-coated carbide grade T6215 for stainless steel
• ISO rhombic CNMG 120404 form with 80° geometry
• Double-sided chipbreaker and cylindrical hole

Robust wear resistance for stainless-steel turning

The combination of a CVD-coated carbide grade and a wear-resistant substrate delivers consistently extended tool life when machining stainless steel under stable cutting conditions. The CVD coating forms a hard surface layer that reduces adhesive wear and improves heat resistance, which in turn helps maintain cutting-edge integrity and a predictable wear curve. For operations requiring reliable repeatability, the insert’s small corner radius (0.4 mm) supports fine finishing passes while the coating assists in preventing notch wear common with austenitic grades.

ISO compatibility and secure clamping for uninterrupted shifts

Designed in the ISO series of turning inserts, the rhombic CNMG form and 80° included angle ensure straightforward compatibility with a wide range of external holders and boring bars. Compatibility depends on form, relief angle, tolerance class, fastening and thickness; the cylindrical hole and standard dimensions (12 mm size, 4.76 mm thickness) simplify interchangeability across ISO tooling systems. The double-sided chipbreaker provides two cutting edges per index, enabling rapid indexing and secure clamping for continuous production runs while maintaining consistent chip control in many stainless-steel machining tasks.

Indexable design that supports shop-floor efficiency

As an indexable, double-sided insert, this solution reduces tool-change frequency and inventory complexity. The geometry and chipbreaker pairing balance productive material removal with a finish-appropriate edge; this helps to lower total tooling cost per component and to standardise process windows across batches. Typical uses include both external and internal turning where stable cutting and good surface quality are required. The insert’s construction and ISO conformity also support quick assessment of holder compatibility, minimising setup time and helping to keep production on schedule.

FAQ

What materials is this insert best suited for?
The CNMG 120404 T6215 is formulated for machining stainless steel, offering wear resistance under stable to slightly interrupted cutting conditions.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the T6215 grade improves chip control and allows two usable cutting edges, increasing productivity and enabling cleaner chip evacuation during turning.

Is this insert compatible with standard CNMG holders?
Yes, the ISO CNMG120404 form and the cylindrical hole are designed for compatibility with holders that match the CNMG geometry, thickness and fastening arrangement.

What finishing quality can be expected with a 0.4 mm corner radius?
A 0.4 mm corner radius supports fine finishing passes and helps achieve consistent surface quality while still providing adequate strength for light to moderate cutting forces.
