CNMG 120404 T9215 Turning insert — Tungaloy

CNMG 120404 T9215 is an ISO rhombic indexable insert for external and internal turning, engineered for productive machining of medium steels.

• CVD-coated carbide T9215 grade
• Optimised for medium steel productivity
• Double-sided chipbreaker, rhombic CNMG form
• Cylindrical hole for secure ISO mounting

Productive performance for medium-steel turning

The CVD-coated carbide in grade T9215 combines high wear resistance with good fracture toughness, making it a dependable choice for continuous to lightly interrupted turning. The coated substrate reduces flank and crater wear, which extends tool life and keeps component dimensions stable over longer production runs. As an indexable insert, it allows quick indexing to fresh cutting edges, reducing downtime and supporting higher throughput in batch and serial production.

Reliable chip control and surface quality

The double-sided chipbreaker built into the rhombic geometry delivers controlled chip formation for most turning operations on medium alloy steels. Stable chip control reduces the risk of entanglement and improves surface finish, which in turn minimises rework. The moderate 0.4 mm nose radius supports fine surface integrity without sacrificing cutting edge strength, so repeatable part quality is achievable even at elevated material removal rates.

Simple integration with ISO tooling systems

This insert follows the ISO 120404 designation and is compatible with standard CNMG holders; compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness. The cylindrical hole and 0° relief angle ensure positive locating and secure fastening in many indexable-turning systems. The standardised format enables straightforward replacement and stocking alongside existing ISO inserts.

Economic advantages in production

Selecting a grade that balances wear resistance and toughness, such as T9215, reduces the frequency of insert changes and minimises unscheduled stops. The combination of a robust substrate and CVD coating helps to achieve a favourable tool life-to-cost ratio in medium-steel applications. For machining strategies that prioritise uptime and consistent results, this indexable insert supports leaner tooling inventories and predictable process windows.

FAQ

What materials is this insert best suited for?
The CNMG 120404 T9215 insert is formulated for medium steel machining; the T9215 grade provides a balance of wear resistance and toughness suited to this material group.

Can this insert be used for interrupted cuts?
Yes. The CVD-coated substrate and robust geometry of the CNMG insert tolerate light to moderate interruptions; for heavy interruptions, a review of holder rigidity and cutting parameters is recommended.

How is the insert mounted in a toolholder?
The insert uses a cylindrical hole and conforms to the ISO 120404 format, so it fits compatible CNMG-style holders that match form, relief angle, tolerance class, clamping method, size and thickness.

Is the edge easily indexable to extend life?
Being double-sided and indexable, the CNMG insert allows quick indexing to fresh edges, which reduces tool change time and improves overall equipment efficiency.

Which chipbreaker should be chosen for different turning tasks?
The double-sided chipbreaker on this insert serves general turning needs on medium steels; for specific materials, surface finish requirements or stability constraints, select the chipbreaker and grade combination that matches the application and machine rigidity.
