CNMG 120412 T9215 ISO turning insert for Turning — CVD-coated carbide, 1.2 mm radius | Tungaloy

A CNMG120412 T9215 indexable insert designed for medium-steel external and internal turning, offering robust wear resistance and compatibility with ISO-standard holders.

• CVD-coated carbide grade T9215
• 80° rhombic geometry for versatile turning
• 1.2 mm corner radius for durable edge
• Double-sided chipbreaker, with cylindrical hole

Consistent cutting performance for medium-steel turning

The CVD-coated carbide composition and the T9215 grade are formulated to combine high wear resistance with good fracture toughness, making the insert a dependable choice for efficient production. This grade is presented as the first option for medium-steel machining and is optimised for continuous and light interrupted cuts, which means longer tool life and fewer indexings during a shift. The coating reduces adhesion and edge wear, so surface finish and dimensional stability remain consistent across longer runs.

ISO compatibility for quick, secure tool changes

The insert adheres to ISO geometry standards, so compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness. That standardisation enables quick tool changes and predictable clamping in a matched holder. Owing to this ISO compatibility, integration into existing tooling systems is straightforward: select a holder matching the CNMG form and the specified relief angle to maintain repeatable seating and secure clamping under varying cutting forces.

Geometry and edge design that support productivity

The 80° rhombic geometry delivers favourable cutting and approach angles for a wide range of turning tasks, while the 1.2 mm corner radius offers a robust cutting edge that resists chipping under typical feed rates. The double-sided chipbreaker configuration provides usable edges on both sides, improving cost-efficiency per insert. Together, these features support higher metal removal rates and stable cutting behaviour, contributing directly to shorter cycle times and improved throughput.

Practical selection and operating guidance

For optimal results, match the insert’s chipbreaker and grade to the workpiece condition and the machining strategy. The indexable insert is supplied with a cylindrical hole for positive fixture engagement; the plate thickness and seat accuracy contribute to stable cutting conditions. Use an appropriate holder with compatible tolerance and clamp set to ensure the rated performance of the insert. Regular inspection of edge condition and adherence to recommended cutting data will extend service life and maintain surface quality.

FAQ

Which materials is this grade best suited for?
The T9215 grade in the CNMG120412 insert is optimised for medium-steel machining; its CVD-coated carbide provides wear resistance and toughness for productive steel turning.

How is compatibility with holders ensured?
Compatibility is governed by the insert’s ISO geometry, relief angle, tolerance class, fixing method, size and thickness; matching these parameters ensures secure seating in the toolholder.

Can the insert be used for interrupted cuts?
The insert is suitable for continuous to light interrupted cuts; for heavy interruptions, a wear‑resistant grade and adjusted parameters are recommended.

What advantages does the 1.2 mm corner radius provide?
A 1.2 mm corner radius strengthens the cutting edge against chipping and improves robustness at higher feeds, supporting steady productivity and longer edge life.

How should the insert be clamped and assembled into the system?
Use a compatible holder with the correct seat form and tolerance, together with the appropriate underlay/clamp set and replacement screws, to achieve secure clamping and repeatable results.
