CNMG 120408 T9215 turning insert by Tungaloy

CNMG120408 T9215 is an ISO rhombic indexable insert designed for external and internal turning of medium steels in standard ISO tool systems.

• CVD-coated carbide T9215 for medium steel
• Stable cutting edge with high wear resistance
• Double-sided chipbreaker for steady chip control
• Rhombic 80° geometry with 0° clearance

Increased throughput with a wear-resistant grade

The CVD-coated T9215 grade combines high wear resistance with good fracture toughness to sustain continuous to slightly interrupted cuts, which translates into longer tool life and fewer indexings. For production environments where cycle times and repeatability matter, the grade supports higher metal removal rates without sacrificing edge integrity. The engineered coating also helps maintain cutting-edge stability under thermal load, contributing to consistent component tolerances and reduced rework.

Geometry engineered for strength and surface quality

The rhombic 80° geometry and 0° clearance provide a secure engagement and a predictable cutting orientation that benefits shoulder cuts and profile turning. The 0.8 mm corner radius improves edge strength and supports a balance between robustness and surface finish, while the double-sided chipbreaker ensures controlled chip formation across a range of feeds. These design elements work together to deliver improved surface integrity and repeatable results in both external and internal turning tasks.

Seamless integration into ISO tool systems

Built to ISO dimensions, the insert fits standard holders when compatibility is matched by form, clearance angle, tolerance class, fastening method, size and thickness. The 12 mm inscribed circle and 4.76 mm thickness allow straightforward replacement in existing tool inventories, simplifying logistics and reducing setup time. Metav Werkzeuge can provide guidance on holder matching and optimal clamping practices to preserve tool life and achieve predictable machining performance.

Practical benefits of the T9215 grade and chip control

The combination of T9215 carbide and a double-sided chipbreaker yields reliable chip control and edge stability when machining medium steels; this supports continuous production runs and moderate interruptions without frequent tool changes. The insert is suitable for a broad range of turning operations, from finishing to medium roughing, where a balance of wear resistance and fracture safety improves uptime and productivity while maintaining component accuracy.

FAQ

What materials is the CNMG120408 T9215 insert best suited for?
The CNMG120408 T9215 insert is optimised for medium steels; the T9215 CVD-coated carbide grade provides high wear resistance and good fracture toughness for these materials.

Can this insert be used for interrupted cuts?
Yes, the T9215 grade and the insert geometry are suitable for continuous to slightly interrupted cutting conditions, offering a compromise between edge strength and wear performance.

How does the chipbreaker affect machining?
The double-sided chipbreaker on the insert maintains consistent chip control, helping to avoid long swarf and promoting stable cutting in a range of feed rates.

What holder compatibility is required for this ISO insert?
Compatibility is determined by the holder’s form, clearance angle, tolerance class, fastening method, inscribed circle size and plate thickness; matching these parameters ensures safe and effective clamping of the insert.

Is the CNMG120408 available in a different corner radius?
This specific designation has a 0.8 mm corner radius; for alternative radii, consult Metav Werkzeuge for available variants and suitable substitutions.
