TNMG160408 AH8015 TNMG indexable insert for turning — Tungaloy

The TNMG160408 AH8015 is an ISO-standard triangular indexable insert designed for external and internal turning, offering a robust combination of PVD-coated carbide and a precision 0.8 mm corner radius for machining heat‑resistant alloys.

• TNMG 160408 ISO geometry
• PVD-coated carbide AH8015
• 0.8 mm nose radius for precision
• Double-sided chipbreaker with hole

Precision and cutting performance for heat‑resistant alloys

The combination of PVD-coated carbide and the AH8015 grade provides a measured balance between wear resistance and cutting-edge stability, which is particularly advantageous when machining heat‑resistant alloys. The moderate coating hardness reduces adhesion and flank wear at elevated temperatures, extending tool life and improving process consistency. A 0.8 mm corner radius offers an optimal trade-off between component surface finish and edge strength, enabling controlled chip formation and reducing the risk of edge chipping during interrupted cuts.

Reliable integration into ISO tool systems for predictable results

Manufactured to ISO dimensions, the insert is compatible with holders when form, clearance angle, tolerance class, attachment, size and thickness match the toolholder specification. The insert’s triangular shape and the presence of a cylindrical hole facilitate secure clamping in standard TNMG pockets; the system typically comprises the insert, a matching outer holder or boring bar, a support shim or clamp set, and replacement screws. This modular setup enables fast index changes, repeatable positioning and reduced setup variability, which in turn increases uptime and supports stable manufacturing processes.

Practical benefits on the shop floor and recommended applications

The double‑sided chipbreaker design permits economical index changes and efficient chip control for both external and internal turning operations. With the AH8015 grade tuned for tough alloys, the insert is a sensible choice for general turning where a compromise between tool life and edge robustness is required. The balanced characteristics support consistent surface quality and machining productivity, while the ISO TNMG format simplifies tool inventory management and holder compatibility for workshops seeking reliable, repeatable results.

FAQ

What materials is this insert suitable for?
The TNMG160408 AH8015 insert is designed as a first choice for general machining of heat‑resistant alloys, offering a balance between wear resistance and edge stability for demanding materials.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius on the TNMG160408 AH8015 increases edge strength for interrupted cuts while still allowing a good surface finish, making it suitable for a wide range of turning operations.

Can the insert be used in standard ISO TNMG holders?
Yes, the TNMG160408 AH8015 follows ISO dimensions and will fit standard TNMG pockets provided the holder’s form, clearance angle, tolerance class, size and thickness match the insert specification.

What is the benefit of the PVD coating on this grade?
The PVD coating on the AH8015 grade reduces adhesion and flank wear at higher cutting temperatures, improving tool life and maintaining cutting‑edge integrity during prolonged turning cycles.

Is the chip control suitable for finishing cuts?
The double‑sided chipbreaker on this insert supports controlled chip formation and can be used in finishing passes where stable chip flow and consistent surface quality are required.
