TNMG 160408 AH8015 — Tungaloy indexable turning insert, PVD-coated, 0.8 mm radius

The TNMG160408 AH8015 is an ISO-format triangular indexable insert for turning, designed for productive machining of heat‑resistant alloys and general external and internal turning tasks.

• Triangular ISO insert, ISO 160408
• PVD-coated carbide for heat-resistant alloys
• 0.8 mm corner radius for edge stability
• Double-sided with cylindrical hole

Reliable cutting performance with PVD-coated carbide

The combination of PVD-coated carbide and the AH8015 grade offers a balanced mix of wear resistance and cutting-edge stability, making it suitable for a wide range of heat‑resistant alloys. The coating reduces flank wear at elevated temperatures and supports longer tool life under interrupted cuts. This results in fewer insert changes and more consistent part quality, which improves cycle-time predictability and lowers per‑component tooling cost in serial production.

ISO format and geometry that simplify tool systems

Built to ISO standard, the ISO 160408 designation ensures compatibility with a broad selection of indexable holders; important parameters for correct fit are form, clearance angle, tolerance class, fastening, size and thickness. The insert is a triangular insert with a cylindrical hole and a 0° rake angle, 4.76 mm plate thickness and a 16 mm inscribed circle, so matching the correct external holder, shim and clamp secures repeatable seating and accurate runout. Having a double‑sided insert doubles the available cutting edges per item, offering cost‑effective indexing for mixed finishing and medium roughing operations.

Stable cutting and chip control for productive turning

The double-sided chipbreaker geometry supports predictable chip formation and evacuation when machining tough alloys, helping to protect the cutting edge and the workpiece surface. The corner radius 0.8 mm provides a robust tip for stable cuts and modest profile work, while the PVD layer keeps the edge integrity under thermal load. Together these features reduce downtime caused by edge failure and contribute to a reliable surface finish, making the insert a practical choice for workshops seeking dependable production results.

FAQ

Which materials is this insert suited for?
The AH8015 grade with PVD coating is optimised for heat‑resistant alloys and offers a broad material coverage for demanding turning tasks, as implemented in the TNMG160408 AH8015 indexable insert.

Is the insert reversible or single‑use?
This is a double‑sided insert, providing two usable edges per side and allowing economical indexing during serial production.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius improves edge robustness and resistance to chipping, supporting stable cuts and consistent surface finish in mixed finishing and medium roughing applications.

What holder features must be checked for compatibility?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and plate thickness; matching these parameters ensures correct seating and repeatable performance.

Can this insert be used for internal turning?
Yes, the ISO‑format geometry and chipbreaker design permit both external and internal turning when paired with a suitable boring bar or holder.
