CNMG120408 T9215 ISO turning insert — rhombic 80°, 0.8 mm, Tungaloy

A CNMG120408 T9215 ISO-standard turning insert designed for medium-steel machining, offering a combination of wear resistance and fracture toughness for continuous to slightly interrupted cuts.

• CVD-coated carbide for high wear resistance
• Rhombic 80° geometry for versatile turning
• 0.8 mm nose radius for reproducible profiles
• Double-sided chipbreaker for cost efficiency

Higher productivity through robust CVD-coated carbide

The CVD-coated carbide grade T9215 delivers elevated wear resistance while maintaining edge strength, which supports higher cutting speeds and longer surface-consistent tool life. For workshops seeking steady throughput, this insert helps reduce downtime from frequent index changes. The coating process forms a hard, wear-resistant layer that is particularly effective in the medium-steel range, combining economical tool consumption with dependable performance.

Precise form and geometry for repeatable components

The rhombic 80° geometry with a 0.8 mm nose radius gives a balance between profile definition and strength, enabling consistent part accuracy across production runs. The insert’s 0.8 mm corner radius produces well-defined contours without compromising edge stability, suitable for finishing and medium-turning tasks. As an ISO-format design, the insert supports straightforward replacement and predictable cutting results when paired with compatible holders.

Practical compatibility and system considerations

Compatibility is determined by insert form, clearance angle (0°), tolerance class, fastening method, size and thickness; ensure the chosen external holder or boring bar matches these criteria. The recommended system includes the ISO insert, an appropriate external holder or boring bar, a supporting shim/clamping set and replacement screws. The double-sided chipbreaker extends life per index and reduces tooling costs by permitting two usable cutting edges before regrinding or disposal.

Application guidance and cost-effective use

Engineered for external and internal turning in continuous to slightly interrupted cuts, the insert’s double-sided design and ISO standardisation improve inventory efficiency and simplify tool planning. The CVD-coated carbide and the chip control geometry together reduce built-up edge and improve surface finish, while the rhombic shape supports versatility across turning tasks. For repeatable production, pairing the insert with the correct holder and machining parameters secures predictable cycle times and component quality.

FAQ

What materials is this insert optimised for?
The CNMG120408 T9215 insert is optimised for medium-steel machining; the T9215 CVD-coated carbide balances wear resistance and fracture toughness for productive turning.

How many usable edges does the insert provide?
With its double-sided design, the insert provides two indexable cutting edges, allowing cost-efficient use before replacement.

Which geometry makes it suitable for versatile turning tasks?
The rhombic 80° geometry combined with a 0.8 mm nose radius allows both profile definition and edge strength, making the insert suitable for a variety of external and internal turning operations.

How should compatibility with holders be checked?
Compatibility depends on form, clearance angle (0°), tolerance class, fastening, size and thickness; select holders that match the CNMG120408 dimensions and mounting style.

Is the insert suitable for interrupted cuts?
Yes—the T9215 grade and robust geometry support continuous to slightly interrupted cuts; heavily interrupted machining may require a different grade or edge preparation.
