CNMG 120408 T6215 — Indexable turning insert for turning, Tungaloy

CNMG120408 T6215 is an ISO rhombic indexable insert designed for turning applications, optimised for machining stainless steels under stable to slightly interrupted cutting conditions.

• CVD-coated carbide T6215 for stainless steels
• ISO CNMG 120408 rhombic insert, 80° angle
• Double-sided geometry with cylindrical hole
• 0.8 mm corner radius for accurate surface finish

Consistent performance for stainless-steel turning

The CVD-coated carbide grade T6215 is designed to resist adhesive wear and maintain a stable cutting edge when machining stainless steels, which are prone to work hardening. The insert’s coating enhances thermal and chemical resistance, reducing built-up edge and improving process reliability. With a double-sided design, the cutting edge economy is maximised, helping to lower running costs while maintaining a predictable surface finish and dimensional control.

Simple integration with ISO tooling and secure clamping

The ISO CNMG 120408 geometry (rhombic, 80°) and a cylindrical hole make this insert compatible with standard CNMG holders when form, clearance angle, tolerance class, fastening method, size and thickness are matched. The 4.76 mm thickness and 12 mm plate size provide robust support in the pocket, while the 0.8 mm corner radius balances edge strength and finish quality. This results in reliable clamping behaviour and reduced vibration risks in stable setups.

Better process control and predictable tool life

Selecting the T6215 grade with its chipbreaker and geometry tailored to stainless-steel turning supports consistent chip formation and easier chip evacuation. The combination of a wear-resistant substrate and a CVD coating generally leads to improved tool-life stability across series production. For operators, this translates into fewer tool changes, shorter set-up interruptions and a more economical machining process overall.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The CNMG120408 T6215 insert is formulated for turning stainless steels, offering improved wear resistance and stable chip control under predominantly stable to slightly interrupted conditions.

Which toolholders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the insert follows ISO CNMG 120408 dimensions and fits standard CNMG indexable turning holders when these parameters match.

Can the insert be indexed to use multiple cutting edges?
Yes. The insert is double-sided, allowing indexing of multiple cutting edges; the cylindrical hole supports secure clamping for repeatable positioning.

Does the CNMG 120408 T6215 suit interrupted cuts?
The T6215 grade performs best in stable to slightly interrupted conditions; for heavy interruptions, choose a grade and chipbreaker optimised for interrupted cutting to preserve edge integrity.

How does the 0.8 mm corner radius affect surface finish?
A 0.8 mm corner radius provides a compromise between edge strength and surface quality; it helps achieve a good surface finish while maintaining sufficient edge robustness for typical turning tasks.
