TNMG 160416 AH8005 TNMG Turning Insert — Tungaloy

A TNMG160416 AH8005 triangular turning insert designed for external and internal turning of heat‑resistant alloys and other hard materials

• PVD-coated wear-resistant AH8005 grade
• ISO TNMG shape with 60° cutting angle
• 1.6 mm corner radius for profile versatility
• Double-sided insert with cylindrical hole

Prolonged tool life through PVD-coated carbide technology

The PVD‑coated carbide grade AH8005 combines a wear‑resistant surface treatment with a robust substrate to extend edge life under sustained cutting temperatures. In practice, the PVD-coated layer reduces flank and crater wear when machining heat‑resistant alloys and other hard materials, which lowers tooling costs per component and maintains dimensional accuracy over longer cycles. The result is a predictable tool change interval and fewer interruptions in a productive turning cell.

Geometry tailored for versatile external and internal turning

The TNMG geometry with a 60° cutting angle and an inscribed circle size of 16 mm offers a balance between edge strength and accessibility in confined bores. The 1.6 mm corner radius provides form stability for light profiling and finishing passes, while the double-sided design supplies two usable edges per index, optimising edge economy. The insert’s 0° clearance angle and 4.76 mm plate thickness contribute to a stable cutting edge when used with appropriate rigid clamping and holders.

Process stability and chip control in demanding materials

Selecting the AH8005 grade together with a matching chipbreaker supports consistent chip formation and reduces built‑up edge in steady cutting conditions. The insert’s specification favours stable setups — a rigid external holder or a suitably supported boring bar is recommended to exploit the grade’s wear resistance. Fewer disturbances from uncontrolled chips and consistent edge behaviour translate into improved surface finish and repeatable cycle times for series production.

Compatibility and selection guidance for reliable integration

Compatibility with cutter holders is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness. The system typically consists of the ISO insert paired with a corresponding external holder or boring bar, plus the required shim/clamping set and replacement screws. When choosing an insert, consider the workpiece material and whether the operation prioritises edge life or surface integrity; match the chipbreaker and grade to the machining strategy for best results.
