TNMG160412 AH120 Tungaloy indexable insert — ISO turning insert for external and internal turning

The TNMG160412 AH120 Tungaloy indexable insert is an ISO‑standard triangular insert engineered for turning operations, offering a sharp cutting edge and process security in demanding machining tasks

• TNMG160412 geometry, 60° triangular insert
• AH120 PVD-coated carbide for wear and chipping resistance
• 1.2 mm corner radius for versatile cutting profiles
• Double-sided chipbreaker, compatible with ISO holders

Consistent performance through advanced coating and grade

The combination of a PVD coating and the AH120 grade carbide delivers a balance of wear resistance and fracture toughness that suits continuous and interrupted turning. This surface treatment increases hardness at the cutting edge while the substrate toughness reduces the risk of edge chipping under variable loads. As a result, tool life is extended and stand‑time becomes more predictable, which supports leaner tool inventory management and fewer unscheduled tool changes.

Geometry and chip control tuned for practical flexibility

A 60° triangular form with a 1.2 mm corner radius and a double-sided chipbreaker provides two usable cutting edges per insert face and stable chip formation in a wide range of cutting conditions. The cylindrical hole and the defined clearances ensure positive clamping and compatibility with ISO holders; the 0° clearance angle promotes a secure fit in many standard toolholders. This geometry allows for both finishing and light roughing passes while keeping surface quality and dimensional repeatability within tight tolerances.

Integration into the turning system and process benefits

The insert is part of an ISO system build that includes a matching outer holder, shim or clamping kit and replacement screws, facilitating straightforward replacement and inventory standardisation. With a plate thickness of 4.76 mm and a nominal size of 16 mm, the insert integrates reliably into standard tool assemblies. The robust edge properties of the AH120 PVD-coated carbide reduce downtime from edge breakouts and improve overall process stability, supporting higher productivity and lower cost per component in serial machining.

FAQ

Which holder types are compatible with this insert?
Compatibility is determined by the insert form, clearance angle, tolerance class, fixing method, size and thickness; the TNMG160412 fits standard ISO 60° triangular turning holders designed for 16 mm inserts.

For which turning tasks is this grade best suited?
The AH120 grade on the TNMG160412 is intended for wear‑resistant, chip‑stable turning where a sharp cutting edge and process security are required, suitable for a wide range of general turning applications.

How many cutting edges are available per insert?
With a triangular, double‑sided design the TNMG160412 offers multiple usable edges; each face can be indexed to present a fresh cutting edge, optimising cost per edge.

What advantages does the PVD coating provide?
The PVD coating on the AH120 substrate enhances hardness and wear resistance at the cutting edge while preserving substrate toughness, resulting in longer life and improved resistance to edge chipping for the TNMG160412.

Is the insert suitable for interrupted cuts?
The combination of a tough carbide substrate and the AH120 coating makes the TNMG160412 appropriate for interrupted turning, where edge stability and resistance to chipping are important.
