CNMG120408 T9215 Tungaloy indexable insert — CVD‑coated carbide for turning, rhombic 80°

The CNMG120408 T9215 is an ISO‑standard rhombic indexable insert designed for external and internal turning applications, offering a balance of wear resistance and fracture toughness for productive medium‑steel machining.

• CVD‑coated carbide T9215 for medium steel
• Rhombic CNMG 80° geometry
• 0.8 mm corner radius for stable edges
• Double‑sided chipbreaker, cylindrical hole

Consistent productivity for medium‑steel turning

The combination of a CVD coating and a wear‑resistant carbide substrate in grade T9215 delivers a reliable life span under continuous to lightly interrupted cuts, enabling higher machining throughput. The cutting material is tailored for medium steel, which means fewer indexings and longer effective cutting time; this reduces unproductive machine downtime and supports predictable batch processing. Compatibility with ISO holders is determined by form, relief angle, tolerance class, fastening method, size and thickness, so matching the insert to the correct clamp and insert seat is essential for repeatable performance.

Precision geometry that simplifies setup and boosts stability

An 80° rhombic geometry and a 0° relief angle provide a secure cutting edge orientation for general turning tasks, while the 0.8 mm corner radius improves edge robustness and reduces the risk of chipping on interrupted surfaces. The insert’s 4.76 mm thickness and 12 mm inscribed circle fit common ISO toolholder families, and the cylindrical hole with secure fastening ensures repeatable seating and torque retention. These design details translate into fewer corrective actions during setup and better surface finish consistency.

System compatibility and straightforward integration into production

As part of an ISO insert system, the package complements a matching external holder or boring bar, plus the required seat support and clamping screws. The double‑sided chipbreaker extends service life by allowing rotation to a fresh cutting edge, improving cost efficiency per edge. Material suitability, as indicated, includes medium steel turning; selecting the correct chipbreaker and insert grade for the workpiece and machining conditions ensures stable chip control and tool life. The insert is supplied as a factory‑new part with the manufacturer’s traceability for workshop planning.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9215 insert is specified for medium steel machining; the T9215 grade combines wear resistance and toughness suited to continuous and slightly interrupted turning of steel.

How does the chipbreaker affect performance?
The double‑sided chipbreaker improves chip control and edge life; using the correct chipbreaker style for the machining type contributes to stable cutting and consistent productivity with this insert.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder form, relief angle, tolerance class, fastening method, size and thickness. The insert’s 12 mm inscribed circle and 4.76 mm thickness fit common ISO toolholder families intended for CNMG geometry.

Can the insert be indexed to a fresh edge?
Yes, the insert is double‑sided, allowing rotation to a second cutting edge and extending the effective service life per insert.

Is the insert suitable for interrupted cuts?
The T9215 grade is designed for continuous to slightly interrupted cutting; for heavily interrupted cuts, assessment of edge strength and cutting parameters is recommended.
