CNMG 120404 T6215 ISO turning insert by Tungaloy — rhombic, 0.4 mm radius

The CNMG120404 T6215 is a CVD-coated carbide turning insert engineered for stable to lightly interrupted cutting in stainless-steel turning, suitable for external and internal operations with standard ISO CNMG holders.

• CVD-coated carbide grade T6215
• Optimised for stainless steel machining
• Rhombic CNMG 120404 with 0.4 mm radius
• Double-sided chipbreaker, cylindrical hole

Proven performance for stainless-steel turning with consistent results

The combination of a CVD-coated carbide substrate and the T6215 grade delivers a balance between wear resistance and edge stability, which translates into longer tool life and fewer changeovers. For operations on stainless steel, heat and work-hardening tendencies require a coating and substrate capable of preserving the cutting edge; this insert reduces flank wear and maintains surface quality during continuous and light interruption cutting. The result is predictable productivity and reduced process variation in serial production.

Secure fit and geometry that simplifies tool set-up

Designed to the ISO CNMG 120404 specification, the rhombic geometry and the 80° included angle give a dependable cutting attitude for general turning. The 0.4 mm corner radius provides a compromise between edge strength and surface finish, while the cylindrical hole and standard mounting dimensions ensure compatibility with a wide range of external holders and boring bars. This standardisation minimises set-up time and helps maintain repeatability across multiple tool stations.

Efficient chip control and stable cutting under mixed conditions

A double-sided chipbreaker improves chip formation and evacuation when machining stainless steel, helping to avoid built-up edge and thermal concentration at the cutting zone. The plate’s coating and chipbreaker combination is optimised for stable to lightly interrupted cuts, enhancing cutting-force consistency and enabling higher average metal removal rates. For process planners, this means fewer interruptions, improved machine uptime and a clearer cost-per-part calculation.

Straightforward integration into existing tool systems

The insert is intended for use as part of a system comprising the ISO indexable insert, an appropriate external holder or boring bar, and the matching shim/clamp kit with replacement screws. Its 4.76 mm thickness and standardised dimensions make retrofits simple where CNMG-style inserts are already in use. Clear compatibility criteria—form, relief angle, tolerance class, fastening method, size and thickness—allow quick verification against existing tooling inventories, supporting efficient tool management and procurement planning.

FAQ

What materials is this insert best suited for?
This insert is optimised for stainless steel machining; the CVD-coated T6215 grade offers high wear resistance under stable to lightly interrupted turning conditions.

Will the CNMG120404 fit existing CNMG holders?
Yes. The CNMG120404 conforms to ISO CNMG dimensions and will fit holders and boring bars designed for standard CNMG inserts, subject to verification of relief angle and thickness.

How does the chipbreaker influence machining performance?
The double-sided chipbreaker on this insert supports controlled chip formation and evacuation, reducing built-up edge and improving surface finish during turning operations in stainless steel.

Is the insert reversible and economical for production runs?
The indexable design is double-sided, which allows rotation to a fresh cutting edge; this offers cost-effective utilisation and extends productive tool life in serial production.
