CNMG120412 T6215 Tungaloy insert — ISO rhombic turning insert, CVD-coated for rostfreier Stahl

CNMG120412 T6215 Tungaloy insert designed for general turning applications, compatible with ISO holders and suitable for stable to lightly interrupted cutting when machining rostfreier Stahl.

• CVD-coated carbide for high wear resistance
• ISO-standard CNMG rhombic geometry
• Optimised for turning rostfreier Stahl
• Double-sided chipbreaker with cylindrical hole

Precision and predictable performance for production turning

The CNMG insert is engineered for repeatable results in shop-floor turning. With a CVD-coated carbide composition the grade offers improved wear resistance, reducing flank wear under steady cutting conditions. Compatibility with ISO holders is ensured by standardised geometry, relief angle and thickness, so the insert integrates into common tool systems without extensive adjustment. The rhombic shape and CNMG form support a balanced cutting edge, while the 80° principal angle contributes to stable engagement and predictable tool life.

System compatibility that speeds up changeovers and stabilises output

This ISO-format insert fits into established clamping systems and is intended for use with a supported holder, clamping kit and replacement screws as part of the tool assembly. The double-sided chipbreaker provides controlled chip formation on both edges, extending indexed life and simplifying inventory management. A cylindrical hole ensures secure fastening and repeatable positioning. For production environments this translates to shorter changeover times, fewer adjustments and steadier component quality — measurable gains in throughput and process reliability.

Edge integrity and process benefits explained

The T6215 grade combines a wear-resistant coating with a robust substrate to resist abrasive and adhesive wear when machining rostfreier Stahl. The CVD coating forms a hard contact layer while the base metal preserves toughness; this balance helps avoid premature chipping in interrupted cuts. The insert’s 1.2 mm corner radius and 4.76 mm thickness contribute to strength at the cutting edge and reduce vibration risk in medium-duty turning. For engineers seeking consistent surface finish and extended indexing intervals, the design reduces unexpected downtime and supports efficient production planning.

FAQ

What holder compatibility is required for this insert?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; the CNMG120412 T6215 insert fits ISO CNMG holders and secures via the cylindrical hole.

Is this grade suitable for interrupted cuts when machining rostfreier Stahl?
The T6215 grade is optimised for stable to lightly interrupted cutting of rostfreier Stahl, offering balanced toughness and wear resistance for such conditions.

How does the chipbreaker affect productivity?
The double-sided chipbreaker on this insert promotes controlled chip formation on both edges, improving surface finish and extending indexed life for more consistent production cycles.

What are the key dimensional data to check before ordering?
Check corner radius (1.2 mm), thickness (4.76 mm), size (12 mm) and principal angle (80°) to ensure correct fit and intended cutting geometry.

Can this insert be used for internal turning operations as well as external?
Yes, the ISO CNMG form is commonly used for both external and internal turning when matched with a suitable holder and correct cutting parameters; the CNMG120412 T6215 is specified for such versatility.
