TNMG220404 AH6235 Tungaloy indexable insert — ISO turning insert, 60° triangular, r0.4

The TNMG220404 AH6235 is an ISO‑standard triangular indexable insert engineered for turning applications, optimised for stainless steels and interrupted cutting where edge stability is critical.

• PVD-coated carbide grade AH6235
• For turning stainless steels and interrupted cuts
• Triangular ISO TNMG 220404, 60° geometry
• Double-sided chipbreaker, central cylindrical hole

High stability and consistent performance for stainless steel turning

The PVD‑coated carbide grade AH6235 is designed to deliver stable chip formation and extended edge life in demanding conditions. The coating reduces friction and improves resistance to built‑up edge during machining of stainless steels, while the tougher substrate helps resist chipping under interrupted cuts. For production environments where tool life and predictable performance matter, this combination translates into fewer insert changes and steadier cycle times.

Geometry that supports adaptable clamping and precise cuts

The 60° triangular geometry with a 0.4 mm corner radius gives a balance between strength and finish capability. The ISO TNMG form ensures compatibility with standard holders when matched by form, rake angle, tolerance class, fastening, size and thickness. The central cylindrical hole and double‑sided design allow rotating the insert when wear occurs, effectively doubling service life per part, which benefits throughput and reduces tooling logistics.

Practical benefits explained for production planning

Chipcontrol is provided by the double‑sided chipbreaker, which is tailored for turning operations and helps maintain consistent swarf evacuation—particularly useful in interrupted or unstable cuts. The insert’s moderate nose radius supports surface finish requirements without sacrificing edge robustness. In short, the component reduces unexpected stoppages and supports higher effective machining time per shift.

Compatibility, handling and system considerations

This item integrates into a standard ISO turning system: the insert, a compatible external holder or boring bar, a suitable shim/clamping kit and replacement screws. Material compatibility, holder choice and the chipbreaker selection should be matched to workpiece material, machining method and machine stability to exploit the insert’s productivity and process security advantages. For less experienced planners, the technical consultancy at Metav Werkzeuge can assist with selection and setup.

FAQ

What materials is this insert suitable for?
The TNMG220404 AH6235 insert is optimised for stainless steels and applications with interrupted cuts; the AH6235 grade offers tougher substrate characteristics for reliable edge control.

How does the PVD coating help in machining?
The PVD coating on the AH6235 grade reduces friction and improves wear resistance, supporting longer tool life and more consistent surface quality when turning stainless steels.

Can the insert be used in standard TNMG tool holders?
Yes, the ISO TNMG220404 form is compatible with standard TNMG holders provided form, relief angle, tolerance class, fastening method, size and thickness are matched.

Is the insert reversible and how does that affect economy?
This is a double‑sided insert with a central hole; reversing worn edges effectively extends insert service life and lowers tooling costs per machined component.

What is the corner radius and how does it influence finish?
The corner radius is 0.4 mm, which provides a compromise between edge strength and achievable surface finish for general turning tasks.
