CNMG 120404-TM T9215 — ISO CNMG120404 rhombic turning insert, CVD‑coated carbide, 0.4 mm corner radius (Tungaloy)

A CNMG 120404-TM T9215 indexable turning insert engineered for medium steel turning, offering high wear resistance and consistent performance in continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215
• ISO CNMG 120404 rhombic geometry
• 0.4 mm corner radius for fine finish
• Double-sided chipbreaker with cylindrical hole

Productivity with reliable wear resistance

The T9215 grade is a CVD‑coated carbide designed to balance wear resistance and fracture toughness, making it particularly effective for medium steel machining. This combination allows stable cutting at elevated feed rates and supports high productivity in continuous to lightly interrupted operations. The coating reduces flank and crater wear, extending effective tool life and lowering changeover frequency, which benefits batch production and longer turning cycles.

Precise ISO geometry for straightforward toolholder matching

The insert follows the ISO CNMG120404 specification with a rhombic 80° included angle and 0° relief angle, which simplifies selection of the corresponding holder. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; ensuring these parameters match the toolholder avoids setup errors and contributes to consistent cutting conditions. The ISO conformity aids tool management and inventory control across multiple machines.

Controlled surface quality and cutting stability

With a 0.4 mm corner radius, the plate offers a favourable compromise between edge strength and surface finish: small radii help achieve finer finishes while maintaining edge integrity under moderate feeds. The double‑sided chipbreaker supports predictable chip formation and evacuation, while the cylindrical central hole and 4.76 mm thickness ensure secure clamping in standard CNMG holders. Together, these features reduce vibration, improve repeatability and support efficient finishing passes.

FAQ

What materials is this insert best suited for?
The CNMG 120404-TM T9215 is optimised for medium steel machining; the T9215 CVD coating enhances wear resistance for continuous to lightly interrupted cuts.

Can the insert be used for finishing passes?
Yes — the 0.4 mm corner radius and the double‑sided chipbreaker facilitate improved surface quality during finishing operations while maintaining adequate edge strength.

How does the ISO CNMG120404 designation affect holder selection?
ISO CNMG120404 specifies the plate geometry and size; matching holder form, relief angle, tolerance class, fastening and thickness ensures secure clamping and correct cutting geometry.

Is the insert suitable for interrupted cuts?
The T9215 grade provides good fracture toughness and is suitable for continuous to lightly interrupted cuts; heavy interruption may require a different geometry or a tougher grade.

What advantages does the CVD coating offer?
The CVD coating improves resistance to flank and crater wear, reducing tool degradation at elevated cutting speeds and supporting longer effective tool life.
