TNMG 160404 AH120 — ISO turning insert, PVD-coated carbide (Tungaloy)

The TNMG160404 AH120 is an ISO‑standard triangular insert designed for general turning operations, offering a sharp cutting edge and high process security for external and internal turning tasks.

• TNMG 160404 geometry, triangular insert
• PVD-coated carbide AH120 for wear resistance
• 0.4 mm corner radius for precise turning
• Double-sided chipbreaker, cylindrical hole

High-performance turning with reliable edge life

The insert’s combination of PVD‑coated carbide and the AH120 grade is optimised for wear resistance and edge stability during continuous turning. This results in consistent cutting performance and fewer insert changes, which supports higher productivity and reduced downtime. For operations where a sharp cutting edge and controlled chip formation are required, the plating and substrate pairing help maintain a stable cutting edge under typical turning feeds and speeds.

ISO compatibility that simplifies toolset selection

The ISO designation and the TNMG form ensure compatibility with a wide range of external holders and boring bars; holder fit depends on form, clearance angle, tolerance class, fastening method, size and thickness. The triangular shape and double‑sided design permit economical use by indexing the insert, while the cylindrical hole secures repeatable clamping and position. This modularity reduces inventory complexity and allows straightforward replacement without extensive re‑qualification of the toolholder system.

Material and chip control explained for safe production

The PVD coating provides a thin, hard surface layer that increases abrasion resistance and helps to preserve a sharp cutting edge, while the carbidesubstrate provides toughness to resist chipping. The included 0.4 mm corner radius balances edge strength with the ability to generate accurate profiles and acceptable surface finish. The double‑sided chipbreaker supports controlled chip formation across a range of steels and typical workshop materials, contributing to process stability and operator safety by reducing long, stringy chips.

FAQ

What materials is this insert suitable for? The TNMG160404 AH120 insert is designed for general turning and provides good performance across a broad range of steels and common workshop materials when the AH120 grade and chipbreaker are matched to the workpiece.

Can the insert be indexed to use both sides? Yes, the triangular TNMG form is double‑sided and can be indexed to the unused cutting edges to extend tool life and lower tooling costs.

What does the AH120 designation mean? AH120 identifies a Tungaloy grade pairing of substrate and PVD coating engineered for wear resistance and edge strength during turning operations where a sharp, reliable cutting edge is required.

How does the 0.4 mm corner radius affect results? A 0.4 mm corner radius improves edge strength and helps achieve consistent surface finish while being small enough to maintain dimensional accuracy on typical turned profiles.

Is the insert compatible with standard ISO holders? The insert conforms to ISO geometry; compatibility with holders depends on form, clearance angle, tolerance class, fastening and size — verify holder specifications to ensure correct fit.
