TNMG 160404 AH725 ISO turning insert, PVD‑coated carbide — Tungaloy

The TNMG 160404 AH725 is an ISO‑standard triangular indexable insert for external and internal turning, designed as a universal, break‑resistant grade for machining steel and rostfreier Stahl.

• PVD‑coated AH725 grade for process security
• ISO TNMG 160404 triangular insert form
• Double‑sided chipbreaker for stable chips
• Cylindrical‑hole clamping for secure fixation

Stable results with a universal PVD‑coated grade

The PVD‑coated AH725 grade delivers consistent performance across varying steels and rostfreier Stahl, combining wear resistance with predictable edge behaviour. The PVD‑coated carbide construction reduces flank wear and supports longer tool life under fluctuating cutting conditions. For shops processing mixed batches or facing frequent material changes, this insert offers a pragmatic balance between durability and versatility, helping to reduce unplanned tool changes and sustain throughput.

Precision geometry that supports reproducible turning

The triangular ISO form with a 60° included angle and a 0.4 mm corner radius provides a reliable geometry for finishing and light‑to‑medium turning tasks. The 0° clearance specification and cylindrical hole design enable straightforward seating and repeatable positioning in compatible holders. Thanks to the insert’s double‑sided layout and defined edge preparation, tool costs per cutting edge are optimised while maintaining cutting stability and surface quality.

Integrated chip control and secure clamping for safer cycles

A double‑sided chipbreaker built into the insert supports controlled chip formation and evacuation, reducing interruption risk and improving surface finish. The insert’s compatibility depends on holder form, clearance, tolerance class, fastening method, size and thickness; when combined with a matched external holder or boring bar, the system gives predictable chip flow and robust clamping. This technical cohesion reduces vibration and supports consistent cycle times in production.

System benefits and recommended applications

As an ISO‑standard turning insert, this component integrates into a typical system comprising an ISO insert, a suitable external holder or boring bar, a clamping plate/kit and replacement screws. The TNMG 160404 AH725 is particularly suitable for external and internal turning where process security and edge stability are priorities—small tooling setups and mixed‑material jobs benefit from its universal, out‑break‑resistant properties. The result is improved uptime, fewer indexings and more consistent component quality.

FAQ

Which materials can be machined with this insert?
The TNMG 160404 AH725 insert is formulated for machining steel and rostfreier Stahl; the AH725 PVD‑coated carbide grade offers broad material coverage and reliable edge behaviour.

What are the key geometric specifications of the insert?
The insert features a 60° included angle with a 0.4 mm corner radius and a 0° clearance angle; it is triangular in form and has a cylindrical hole for clamping.

Is the insert single‑ or double‑edged?
This ISO triangular insert is double‑sided, providing two usable cutting edges per side and enabling economic indexing.

For which operations is the insert intended?
The component is intended for external and internal turning operations where stable chip control and process security are required.

How is compatibility with holders ensured?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; a matched external holder or boring bar, plus the appropriate underlay and screws, ensures secure seating and repeatable performance.
