TNMG 160408 AH120 Turning Insert — PVD-coated carbide, 0.8 mm corner radius (Tungaloy)

The TNMG160408 AH120 is a triangular ISO-standard turning insert engineered for external and internal turning where a sharp cutting edge and process security are required.

• PVD-coated AH120 for high wear resistance
• Sharp cutting edge and process security
• Double-sided chipbreaker for economical use
• Triangular 60° form with 0.8 mm corner radius

Engineered for consistent cutting performance

The insert is supplied in a PVD-coated carbide grade (AH120) that combines wear resistance with resistance to chipping, resulting in extended tool life and fewer interruptions. The PVD layer reduces abrasive wear and stabilises the cutting edge under varying cutting conditions; as a consequence, machining runs can be planned with greater confidence. For operations where consistent surface quality and predictable tool change intervals matter, this specification supports improved productivity and reduced scrap rates.

Optimised geometry for secure clamping and predictable results

The triangular, 60° geometry and the cylindrical hole ensure secure fastening in compatible holders, while the 0° relief provides a defined cutting orientation for routine turning tasks. The insert thickness of 4.76 mm and the ISO designation make it straightforward to match the component with standard external holders or boring bars. Because compatibility depends on form, relief angle, tolerance class, fastening, size and thickness, selecting a matching holder guarantees repeatable clamping and minimal run-out, which in turn improves dimensional accuracy.

Cost-efficient performance through double-sided design

A double-sided chipbreaker extends usable life by allowing multiple cutting edges to be indexed before replacement, reducing tooling costs per part. The 0.8 mm corner radius strikes a balance between edge strength and surface finish: a rounded corner reduces edge chipping risk while still enabling a good surface quality in general turning. This combination is especially advantageous for batch production where tool-change frequency and predictable wear behaviour have a direct impact on operating costs.

Integration into the machining process and selection guidance

The indexable insert is part of a system consisting of the ISO insert, a matching external holder or boring bar, clamping seat and fastening screw. For best results, the chipbreaker and grade should be chosen according to workpiece material, machining style and machine-tool rigidity: a stable setup reduces vibrations and preserves the sharp cutting edge. Technical consultants can advise on matching insert geometry and chip control to the machining scenario, enabling fewer test cuts and faster process ramp-up.

FAQ

What materials is this insert suitable for?
The TNMG160408 AH120 insert is a general-purpose turning grade; the AH120 PVD-coated carbide is designed for wear resistance and process security across a broad range of turning jobs—selection of the correct chipbreaker and cutting data should be based on the specific workpiece material.

How many usable edges does the insert provide?
With a triangular form and a double-sided chipbreaker, the insert offers multiple indexable edges; the design helps to reduce tooling cost per edge and enables economical edge changes during production.

What does the 0.8 mm corner radius influence in machining?
A corner radius of 0.8 mm increases edge strength and reduces the likelihood of chipping while maintaining a good surface finish in typical turning operations; it is a compromise between robustness and fine surface quality.

Is the insert compatible with standard ISO holders?
The insert follows ISO designation 160408; compatibility with a holder depends on matching form, relief angle, tolerance class, fastening, size and thickness, so use a holder specified for TNMG160408-style inserts.

What benefit does the PVD coating bring?
The PVD coating on the AH120 grade reduces abrasive wear and improves edge life under variable cutting conditions, supporting longer tool life and more consistent surface quality.
