CNMG120412 T9215 CNMG Turning Insert by Tungaloy — CVD-coated carbide, 1.2 mm radius

CNMG120412 T9215 is a rhombic ISO turning insert designed for external and internal turning applications, optimised for medium steel machining.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• ISO rhombic insert, 80° cutting edge
• 1.2 mm corner radius for edge strength

Consistent cutting performance for medium steels

The CVD coating on this carbide insert provides a hard, wear-resistant surface that balances wear resistance with fracture toughness. Designed as grade T9215, the geometry and coating combination make it a first choice for medium steel operations, enabling stable cutting in continuous to slightly interrupted cuts. The 1.2 mm corner radius increases edge strength and reduces chipping risk, which leads to more consistent component tolerances and fewer tool changes. This results in measurable productivity gains and predictable process windows on parts where dimensional repeatability matters.

Easy integration with ISO tooling systems

Compatibility with holders is governed by form, clearance angle, tolerance class, clamping method, size and thickness; the ISO designation ensures straightforward selection and interchangeability. The ISO-standard rhombic shape with an 80° cutting edge and a 0° clearance angle fits common external and internal holder families, simplifying inventory and changeover. The plate’s double-sided chipbreaker design offers two usable edges per side, extending effective cutting life and reducing part-to-part downtime. For reliable assembly, check holder match by form and thickness and select a clamping set that matches the insert’s cylindrical hole style.

Maximise productivity and extend tool life

A targeted approach—matching feed, speed and the insert’s properties—unlocks the grade’s performance. The T9215 substrate resists abrasive wear while maintaining edge integrity in demanding turning cycles, allowing higher cutting parameters without compromising surface finish. Combined with the insert’s geometry, the design supports easy chip control in a range of feeds, which reduces built-up edge and stabilises cutting forces. For process optimisation, favour steady clamping and minimal run-out at the toolholder; controlled cutting conditions help exploit the insert’s wear profile and deliver longer intervals between indexings, improving overall shop-floor efficiency.

FAQ

What materials is this insert best suited for?
The Tungaloy CNMG120412 T9215 insert is optimised for medium steel; the T9215 grade combines wear resistance and toughness for productive turning of such materials.

How does the 1.2 mm corner radius affect cutting?
A 1.2 mm corner radius increases edge strength and reduces the likelihood of chipping, improving dimensional stability and allowing slightly higher feeds while maintaining surface quality.

Is the insert compatible with standard ISO holders?
Yes. The CNMG120412 follows ISO geometry; compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness, so verify these attributes when selecting a holder.

Is the insert double-sided and what is the hole style?
The insert features a double-sided chipbreaker and is supplied with a cylindrical hole, providing multiple indexing options and straightforward clamping in compatible systems.

Where can the CNMG120412 be ordered and who supplies technical advice?
The CNMG120412 T9215 insert is available through Metav Werkzeuge; their consultants can advise on holder selection, cutting parameters and process integration.
