TNMG 160408 AH120 ISO turning insert — triangular, PVD‑coated carbide, Tungaloy

A TNMG 160408 AH120 is an ISO‑standard triangular turning insert engineered for external and internal turning, offering high wear resistance and stable cutting performance in a broad range of turning tasks

• ISO‑standard triangular insert
• PVD‑coated cemented carbide for wear resistance
• Double‑sided chipbreaker for stable chip control
• Cylindrical hole; compatible with ISO holders

High reliability for demanding turning operations

The insert is built on a cemented carbide substrate with a PVD coating classified under the AH120 grade, which provides a good balance between wear resistance and fracture toughness. This combination reduces flank wear and maintains a sharp edge over longer tool life, making the component especially suitable where both a keen cutting edge and process security are required. The 60° geometry and 0.8 mm corner radius contribute to repeatable dimensional accuracy and help to achieve consistent surface finish in external and internal turning. For engineers selecting cutting data, the AH120 grade typically allows conservative feeds with improved edge stability, reducing the risk of premature chipping in interrupted cuts.

Practical advantages in the workshop and on the shop floor

As an ISO turning insert the plate integrates into standard toolholder systems when matched by form, clearance, tolerance class, clamp method, size and thickness. The triangular plate with a cylindrical hole and a nominal thickness of 4.76 mm offers secure fixation and simple indexation. The double‑sided chipbreaker design supports predictable chip formation and evacuation, which in turn eases coolant and cycle planning and improves cycle time reliability. For production planners the result is fewer unplanned tool changes and a steadier process window, which helps to optimise throughput and reduce downtime.

Application guidance and material versatility

This insert is specified for turning and is recommended where a robust, wear‑resistant grade is needed. The plate is suitable for both external and internal turning when the matching holder or boring bar is used, and the choice of chipbreaker and grade should be aligned with workpiece material and machining stability. Typical setups benefit from the 60° lead angle when machining common steels or mixed batches; the PVD layer on the AH120 grade enhances performance when run at moderate to elevated cutting speeds. In practice, selecting a slightly lower feed with the 0° clearance angle can protect the cutting edge in low‑rigidity applications while preserving surface quality.

FAQ

What materials is this insert suitable for?
The AH120‑graded PVD‑coated cemented carbide insert is intended for turning a wide range of materials; selection of the chipbreaker and cutting data should be adapted to the specific workpiece material and machining stability.

How does the double‑sided chipbreaker affect performance?
A double‑sided chipbreaker provides reproducible chip formation and evacuation in both index positions, improving process stability and reducing the frequency of tool‑related interruptions when using the TNMG 160408 AH120 insert.

What are the key dimensions to check when fitting the insert?
Check the ISO designation (160408), the plate thickness of 4.76 mm, the 60° geometry and the cylindrical hole for correct compatibility with the chosen holder; these determine fit and clamp method.

How many indexable edges are available per insert?
The triangular TNMG form offers two usable edges per side with a double‑sided configuration, enabling multiple indexings before replacement.

Is the insert suitable for interrupted cuts?
The AH120 grade combines wear resistance with edge robustness; it is appropriate for many interrupted cutting scenarios, though cutting parameters and fixture rigidity should be considered to prevent chipping.
