CNMG 090308 T9215 — ISO rhombic turning insert by Tungaloy (CVD‑coated carbide, double‑sided chipbreaker)

The CNMG090308 T9215 is an ISO‑standard rhombic turning insert designed for external and internal turning in medium‑steel applications, combining a robust CVD coating with a geometry optimised for productivity and process stability.

• ISO rhombic insert CNMG090308
• CVD‑coated carbide T9215 for medium steel
• Double‑sided chipbreaker for consistent control
• 0.8 mm corner radius and 3.18 mm thickness

Reliable cutting performance for medium‑steel turning

The combination of a CVD‑coated carbide base with the T9215 grade provides a balanced mix of wear resistance and fracture toughness, making it a practical choice for continuous to slightly interrupted cuts in medium steels. The coating reduces abrasive wear and thermal loading at the cutting edge, which translates into longer effective tool life and improved process consistency. For production lines focusing on throughput, this balance supports higher metal removal rates while maintaining acceptable edge stability and surface integrity.

Geometry that supports setup simplicity and edge strength

The ISO rhombic shape with an included angle suitable for general turning offers predictable engagement and simple seat‑up in compatible toolholders. The insert's 0° relief angle, 0.8 mm corner radius and 3.18 mm thickness increase edge support and reduce the risk of chipping under moderate interruptions. These geometric choices help maintain dimensional accuracy over longer tool life and simplify holder selection, since compatibility is governed by form, relief angle, tolerance class, fastening, size and thickness — standard parameters for ISO‑type turning systems.

Chip control and process stability for consistent results

The double‑sided chipbreaker is engineered to promote controlled chip formation when machining medium steels, reducing chip tangling and improving evacuation from the cut. Better chip control reduces secondary operations and machine downtime while enhancing surface quality, which supports repeatable parts production. In automated or semi‑automated turning cells, this predictable chip behaviour contributes directly to higher overall equipment effectiveness and fewer unplanned interventions.

Practical integration into production workflows

Integration of the insert into a turning system is straightforward: pair the insert with a suitable external holder or boring bar, underlay/shim and the recommended clamp and screws. Attention to holder compatibility and correct mounting ensures the intended cutting geometry and repeatability. For selection, match the chipbreaker and grade to the workpiece material and process stability; where vibration or heavy interruptions are expected, opt for more robust clamping and consider adjusting feed to benefit from the insert's supported edge strength. For specific cutting data or series production parameters, rely on supplier recommendations or consult technical support.

FAQ

Which materials is this insert intended for?
The CNMG090308 T9215 insert is specified for medium‑steel machining and performs best in continuous to slightly interrupted turning operations on steel grades within that range.

What advantages does the T9215 grade offer?
The T9215 grade combines CVD coating and a carbide substrate to deliver enhanced wear resistance with good fracture toughness, supporting higher productivity and dependable edge life in medium‑steel turning.

Is this insert indexable and reversible?
Yes — the insert is double‑sided with a chipbreaker on both faces, allowing indexing to a fresh cutting edge and therefore multiple effective cutting positions per insert.

What are the key geometric values to consider for holder selection?
Important values are the corner radius (0.8 mm), thickness (3.18 mm), insert size (09), relief angle (0°) and the rhombic plate form; holders must match these parameters and the ISO designation for secure and repeatable clamping.

How should chip control be managed with this insert?
Use the built‑in double‑sided chipbreaker and select appropriate feeds and depths for the workpiece stability; the chipbreaker promotes compact chips and improved evacuation, reducing secondary handling and machine interruptions.
