TNMG160412 AH6235 indexable insert for turning — PVD-coated carbide by Tungaloy

TNMG160412 AH6235 is a triangular indexable insert for turning operations, designed as a tough, PVD-coated carbide grade for interrupted cuts and challenging stainless steel machining.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel turning
• Double-sided chipbreaker, triangular insert
• ISO TNMG 160412 form with 1.2 mm radius

Durability and material match for reliable stainless steel turning

The PVD-coated carbide grade AH6235 is formulated for higher toughness, which reduces the risk of crater formation and chipping during stop-start cycles and interrupted cuts. In machining rostfrei components where built-up edge and thermal loading are common, this grade helps maintain a stable cutting edge for longer. Choosing a tougher grade over a harder, more brittle coating can result in fewer insert changes and increased uptime, improving process economics in volume production.

Precise geometry for secure clamping and consistent results

The triangular geometry complies with ISO TNMG dimensions and a 60° cutting angle, offering a robust contact area in the pocket and straightforward indexability. The insert features a 1.2 mm corner radius and a 4.76 mm plate thickness, with a 0° clearance angle and a cylindrical hole for secure fastening. These measured parameters aid repeatability across tool changes and simplify holder selection where form, tolerance class and thickness must match to ensure correct seat and clamping.

Better chip control and fewer tool changes for higher productivity

Equipped with a double-sided chipbreaker, the insert supports effective chip control under variable cutting conditions and contributes to consistent surface finish in external and internal turning. The combination of chipbreaker geometry and the PVD-coated surface reduces friction and wear rates, extending effective tool life. For production environments this can translate into fewer interruptions for tool change and lower unit costs per component, a clear rational advantage for process planners and shopfloor managers.

System thinking: compatibility and application guidance

This insert is part of a standard ISO insert system and requires a matching holder or boring bar defined by form, free angle, tolerance class, fastening method, size and thickness. The triangular insert is suitable for both external and internal turning; for interrupted cuts or materials with higher breakout risk the AH6235 grade is recommended. For specific holder matching or process parameter recommendations, Metav Werkzeuge can provide application data, recommended clamping torque and reconditioning advice to integrate the insert into an existing tool setup.

FAQ

What materials is this insert best suited for?
The TNMG160412 AH6235 insert is optimised for machining stainless steel and applications with interrupted cuts where a tougher, PVD-coated carbide is advantageous.

Is the insert indexable on both sides?
Yes, the triangular design with a double-sided chipbreaker allows indexing to fresh cutting edges, extending the insert's usable life.

Which holders are compatible with this insert?
Compatibility is determined by ISO TNMG form, free angle, tolerance class, fastening type, size and thickness; Metav Werkzeuge can advise on suitable external holders and boring bars.

What are the key dimensional data for tool setup?
Key values include a 1.2 mm corner radius, 16 mm plate size, 4.76 mm thickness and a 60° angle; use these when selecting the appropriate pocket and clamping hardware.

Can this insert handle interrupted cuts and heavy machining?
The AH6235 grade and its tougher substrate are specified for interrupted cuts and operations with increased breakout risk, offering improved resistance to chipping.
