TNMG 160412 AH8015 Tungaloy turning insert — PVD-coated carbide, 60° geometry

A TNMG160412 AH8015 indexable insert engineered for external and internal turning, optimised for heat‑resistant alloys and general turning operations

• PVD-coated carbide AH8015 for heat-resistant alloys
• 60° cutting geometry for stable chip control
• 1.2 mm corner radius for robust edge strength
• Triangular, double-sided insert with cylindrical hole

Consistent machining performance for heat‑resistant alloys

The PVD-coated AH8015 grade delivers a measured balance between wear resistance and edge stability, making this insert well suited to machining heat‑resistant alloys where thermal and abrasive loads vary. As an ISO-compatible indexable component, the insert supports predictable tool life and repeatability in batch production, reducing the frequency of insert changes and stabilising process costs.

Geometry that supports versatile turning strategies

The 60° cutting geometry combined with a 0° clearance angle provides a flexible solution for a broad range of turning tasks. The triangular form offers multiple cutting edges per insert position, while the central cylindrical hole ensures secure clamping in standard carriers. The result is a geometry that supports consistent cutting forces and straightforward indexability in both light‑duty finishing and heavier roughing passes.

Improved edge strength and chip behaviour

The 1.2 mm corner radius increases edge robustness and helps dampen vibration at the cutting point, extending service intervals where interrupted cuts occur. The integrated double-sided chipbreaker promotes controlled chip formation, improving evacuation and reducing the risk of re-cutting. Combined with the PVD layer, these features maintain a stable cutting edge and contribute to consistent surface quality.

Easy integration into established tool systems

Compatibility with toolholders is determined by form, clearance, tolerance class, clamping method, size and thickness; this insert follows the established ISO conventions for triangular indexable inserts. The complete system typically comprises a matching holder, shim/clamping set and securing screws, enabling quick replacement and minimising set‑up time on the machine. Such system‑level clarity supports lean tooling management in production environments.

Practical benefits for production throughput and reliability

The TNMG160412 AH8015 insert is intended to provide a pragmatic mix of performance and longevity: fewer edge failures, predictable tool changes and improved process stability. For manufacturing operations seeking dependable repeatability on heat‑resistant alloys, the indexable insert format reduces inventory complexity while maintaining the flexibility to adapt to different holder types and turning strategies.
