CNMG 120404 T9215 indexable turning insert — CVD‑coated carbide, 0.4 mm radius (Tungaloy)

A CNMG120404 T9215 indexable insert designed for turning operations, offering high wear resistance and stable performance for continuous to lightly interrupted cuts in medium steels

• ISO rhombic 80° geometry
• CVD-coated carbide grade T9215
• Double-sided chipbreaker for chip control
• Cylindrical hole with secure clamping

Consistent performance for medium‑steel turning

The combination of a CVD‑coated surface and a carbide substrate provides a high level of wear resistance and enhanced fracture toughness. The grade T9215 is specified for the middle range of steel machining, balancing lifetime and productivity when machining under continuous and lightly interrupted cutting conditions. The coating reduces built‑up edge and improves thermal stability; this supports longer cutting intervals and fewer index changes, which translates into measurable operational efficiency.

Geometry and clamping that reduce setup risk

The ISO rhombic 80° form with a 0.4 mm corner radius and a 0° relief angle gives a predictable cutting line and consistent engagement in both external and internal turning. The insert is double‑sided, allowing two cutting edges per index, and the cylindrical hole ensures stable locating and clamping in ISO‑compatible holders. Compatibility with a toolholder depends on form, relief angle, tolerance class, fastening method, size and thickness — selecting the correct holder, backing pad and screws completes the system for safe, repeatable clamping.

Productivity and process reliability in daily production

A well‑matched chipbreaker and the T9215 grade support stable chip formation and controlled evacuation, reducing the risk of rework and downtime. For workshop planning, the insert forms part of a system: indexable insert, suitable external holder or boring bar, backing plate/clamp set and replacement screws. This reduces spare‑part complexity and helps maintain throughput. The overall result is improved cycle times and consistent surface quality with fewer tool interventions.

FAQ

What materials is this insert best suited for?
The CNMG120404 T9215 Tungaloy indexable insert (SKU 6773892‑Tungaloy) is optimised for medium‑range steel machining; the T9215 grade combines wear resistance and fracture safety for productive turning in such materials.

Can this insert be used for both external and internal turning?
Yes. The rhombic 80° geometry and the double‑sided design make the insert suitable for both external and internal turning applications when mounted in a compatible ISO holder.

How does the CVD coating benefit performance?
The CVD coating on the carbide substrate improves thermal stability and reduces built‑up edge, which enhances tool life and maintains consistent surface finish under continuous to lightly interrupted cuts.

What determines holder compatibility for this insert?
Compatibility is determined by the insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the holder matches the CNMG120404 dimensions and the clamping system (cylindrical hole and screw) for secure fixing.

Is the chipbreaker suitable for long turning passes?
The double‑sided chipbreaker aids chip control and stable formation, supporting longer uninterrupted passes; choose the chipbreaker profile and cutting parameters to match material and rigidity for optimal results.
