CNMG 120408 T9215 ISO turning insert for medium steel machining — Tungaloy

The CNMG 120408 T9215 is an ISO-standard rhombic turning insert designed for medium steel machining, providing a CVD-coated carbide grade tailored to continuous and lightly interrupted cuts.

• CVD-coated carbide grade T9215
• Optimised for medium steel productivity
• ISO 120408 rhombic insert, 0.8 mm radius

Consistent performance for medium-steel turning

The insert is built from carbide with a CVD-coated surface in grade T9215, which combines high wear resistance with fracture resistance to support higher cutting parameters under stable conditions. This composition makes the tool particularly suitable for efficient machining of medium-strength steels where a balance between tool life and process reliability is required. The design supports continuous and light interrupted cuts, helping to maintain consistent component tolerances and surface quality while reducing the frequency of tool changes.

Easy integration with ISO tooling systems

Compatibility with toolholders is determined by form, relief angle, tolerance class, clamping method, size and thickness; the insert’s ISO-standard geometry and rhombic shape simplify selection for common turning holders. Key geometrical data such as the 0.8 mm corner radius, 4.76 mm plate thickness and 80° included angle are relevant when matching to a clamping seat and cutting strategy. The insert features a cylindrical hole for positive location and a double-sided chipbreaker that offers two usable cutting edges per side, increasing economy per index and easing inventory management.

Productivity advantages and process security

A well-chosen chipbreaker and the T9215 grade support stable chip formation and improved surface finish, which in turn reduces downstream rework and cycle time. The two-sided chipbreaker construction extends service intervals and lowers cost per cutting edge, while the robust substrate and coating combination ensures repeatable performance across batches. For practical use, select the chipbreaker and grade according to workpiece stability and machining mode; this approach secures process reliability and predictable tool life, contributing to higher overall shop-floor productivity. If additional application data are required, technical documentation and cutting parameters can be provided.

FAQ

What materials is this insert best suited for?
The CNMG 120408 T9215 insert is optimised for medium steel machining; the T9215 CVD coating and carbide substrate deliver wear resistance suited to this material group.

How does the chipbreaker design affect performance?
The double-sided chipbreaker on this insert promotes controlled chip formation and stable cutting forces, which supports surface quality and reduces the risk of built-up edge during turning.

Which geometrical features aid holder compatibility?
Key dimensions such as the rhombic form, 80° included angle, 0.8 mm corner radius and 4.76 mm thickness ensure that the insert aligns with ISO-standard external turning holders when the correct tolerance class and clamping are observed.

How many usable cutting edges are available per insert?
With a double-sided design, the insert provides multiple indexing positions; the exact count depends on orientation and chipbreaker usage, but the configuration is intended to extend service life and reduce tooling costs.

Is this insert suitable for interrupted cuts?
Yes — the carbide substrate and T9215 coating support continuous and light interrupted cuts; for heavy interruptions, a different geometry or a more impact-resistant grade should be considered.
