CNMG 120408 T9215 ISO turning insert for turning — Tungaloy

A CNMG120408 T9215 turning insert engineered for external and internal turning in medium‑strength steel, combining CVD‑coated carbide performance with an 80° rhombic geometry.

• CVD-coated carbide grade T9215
• 0.8 mm corner radius for versatile turning
• 80° rhombic ISO geometry for stable cutting
• Double-sided chipbreaker, cylindrical hole

Consistent productivity through optimised coating and substrate

The combination of a CVD‑coated surface and a high‑performance carbide substrate in grade T9215 provides a reliable balance between wear resistance and toughness. This means longer cutting life under steady cutting conditions and improved resistance to edge chipping during slight interruptions. For production environments aiming to reduce downtime, the coating enhances abrasive wear protection while the substrate maintains integrity under load, resulting in a predictable tool life and fewer insert changes.

Geometry and edge design that improve process stability

An 80° rhombic geometry with a 0.8 mm corner radius contributes to stable cutting mechanics and flexible application across a range of turning tasks. The insert’s double‑sided configuration and cylindrical hole support secure clamping and economical indexing. Because the insert conforms to ISO standards, compatibility with a wide selection of external holders is determined by form, clearance angle, tolerance class, fastening style, size and thickness, which simplifies tool‑holder selection and reduces setup time.

Practical benefits for machining medium steel

Designed as a first choice for medium steel machining, this grade is suited to continuous and lightly interrupted cuts, enabling higher material removal rates without compromising surface finish. The integrated chipbreaker promotes consistent chip formation and evacuation, lowering the risk of built‑up edge and facilitating predictable cycle times. As a result, process planners can rely on repeatable results and consistent component quality even in longer batch runs.

System integration and handling advantages

The insert’s standardised dimensions and thickness (4.76 mm) make it straightforward to stock and manage within an existing tool inventory. Its rhombic form and ISO designation mean changeover procedures are quick and intuitive for trained operators, while the double‑sided design halves tooling costs per cutting edge compared with single‑sided alternatives. Clear product identification and SKU labelling also support inventory control and procurement efficiency.

FAQ

What materials is this insert best suited for?
This insert in grade T9215 is optimised for medium‑strength steel machining; the CNMG120408 geometry supports consistent performance in continuous and lightly interrupted turning.

Can the insert be indexed to use both cutting edges?
Yes, the insert is double‑sided; both sides can be indexed to extend cutting edge life and improve cost efficiency per edge.

How does the CVD coating affect cutting performance?
The CVD‑coated layer on the T9215 grade improves abrasive wear resistance, which helps to maintain edge integrity and supports longer cutting intervals under steady conditions.

Is the insert compatible with ISO holders?
The rhombic CNMG shape and ISO designation mean compatibility with ISO holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness as described in the product system build.

What are the key handling advantages for production shops?
Standardised dimensions, a double‑sided design and a cylindrical hole for secure clamping make the insert easy to stock, index and mount, reducing changeover time and supporting stable process control.
