CNMG120408 T9215 Tungaloy turning insert — CVD-coated carbide, 0.8 mm radius

CNMG120408 T9215 Tungaloy turning insert designed for precise external and internal turning in medium-steel applications, compatible with ISO holders when form, clearance, tolerance class, fastening, size and thickness match

• ISO‑standard rhombic insert CNMG120408
• CVD-coated carbide grade T9215
• Double-sided chipbreaker for stable chips
• Corner radius 0.8 mm for versatile turning

Consistent cutting performance for medium-steel components

The CVD-coated carbide composition of this rhombic insert is tuned to deliver a long tool life in the middle range of steel machining. The T9215 grade combines elevated wear resistance with good fracture toughness, which supports higher material removal rates under continuous or slightly interrupted cuts. In practice, this means fewer toolchanges and more predictable cycle times, improving overall process reliability while helping to keep machining costs under control.

Secure fit and standardised geometry reduce setup risk

Compatibility with a holder depends on several defined parameters such as form, clearance angle, tolerance class, fastening method, size and thickness. The insert's rhombic form, 12 mm size and 4.76 mm thickness follow ISO conventions, and the cylindrical hole allows robust clamping in standard ISO housings. These standardised dimensions ease tool change routines and support reproducible cutting positions, which is particularly valuable in production lines where repeatability and quick reindexing are required.

Stable chip control and operational productivity

The double-sided chipbreaker design actively controls chip flow and helps avoid tangling or re-cutting of swarf, which contributes to a safer, cleaner machining environment and a more consistent surface finish. The 0.8 mm corner radius offers a balance between edge strength and dimensional accuracy for a wide range of turning tasks. Combined with the CVD coating, this geometry helps maintain a sharp cutting edge for longer, enabling higher productivity and reduced downtime for maintenance.

Practical advantages for workshop integration

As an ISO turning insert, the component fits into established tool management systems and spares inventories, simplifying logistics. The plate is suitable for both external and internal turning operations; selecting the correct chipbreaker and grade for the workpiece material and cutting conditions ensures stable results. The Tungaloy grade is engineered to offer habitual process security in medium-steel machining, making it a pragmatic choice for workshops aiming to balance throughput with surface quality.

FAQ

What materials is this insert designed for?
The CNMG120408 T9215 insert is optimised for medium steel; the T9215 CVD-coated carbide grade delivers wear resistance and fracture toughness suited to that material class.

How does the chipbreaker influence machining?
The double-sided chipbreaker provides controlled chip formation and evacuation, improving surface finish consistency and reducing the risk of chip-related interruptions when using the CNMG120408 insert.

Can this insert be used in standard ISO holders?
Yes; the insert follows ISO dimensions and fits holders that match the form, clearance angle, tolerance class, fastening method, size and thickness specified for CNMG120408.

What does the 0.8 mm corner radius mean for results?
A 0.8 mm corner radius gives a compromise between edge strength and dimensional accuracy, supporting robust turning operations while maintaining acceptable surface quality for many medium-steel components.
