TNMG 160404 AH8015 indexable turning insert for turning — Tungaloy

The TNMG160404 AH8015 is an ISO‑standard triangular indexable insert engineered for external and internal turning of heat‑resistant alloys, combining a PVD coating with a robust carbide core for stable, repeatable performance.

• TNMG 160404 insert, ISO triangular form
• PVD-coated carbide AH8015 for heat-resistant alloys
• Double-sided chipbreaker for stable chip control
• 60° geometry with cylindrical hole for secure clamping

Consistent cutting performance that extends tool life

The combination of a PVD-coated surface and a carbide substrate provides wear resistance while maintaining edge stability under thermal and mechanical load. The AH8015 grade is tuned for the general machining of heat‑resistant alloys, offering a compromise between resistance to abrasive wear and the ability to retain a sharp cutting edge. In practical terms, this means fewer index changes and more predictable intervals between regrinds, which supports higher productivity and reduced tooling costs. The coating reduces adhesion and temperature‑related wear, so the insert keeps cutting reliably even during prolonged cutting cycles.

Secure clamping and straightforward ISO compatibility

A standardised triangular form with a 60° geometry and a cylindrical hole ensures compatibility with a wide range of ISO‑type holders; clamping fit is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The zero‑degree clearance angle and the inscribed circle size of 16 mm are key mechanical parameters that influence seat fit and orientation. Using the correct holder and backing plate gives secure clamping, improved concentricity and reduced vibration — all of which contribute to repeatable surface finish and dimensional accuracy in turning operations. This predictability simplifies tool selection in production environments.

Stable chip control and efficient turning cycles

The double-sided chipbreaker provides controlled chip formation for both external and internal turning applications, improving evacuation and reducing the risk of chip entanglement. Being double‑sided increases the number of usable cutting edges per insert, enhancing cost efficiency per index. Match the chipbreaker style and grade to the workpiece material and rigidity of the setup to exploit the insert’s full potential: in less rigid setups choose gentler parameters; in stable setups higher feeds and speeds can be applied for faster metal removal while maintaining chip control and surface quality. Together, these features support a productive machining process with predictable results.

FAQ

What materials is this insert suitable for?
The TNMG160404 AH8015 insert is designed primarily for heat‑resistant alloys; the AH8015 grade balances wear resistance and edge stability for general machining in these materials.

Is the insert compatible with standard ISO toolholders?
Yes — the triangular ISO designation and the 16 mm inscribed circle make the insert compatible with holders that match the insert form, tolerance class and fixing method.

How does the PVD coating benefit machining?
The PVD coating on this carbide grade reduces adhesion, improves temperature resistance and slows abrasive wear, extending the useful tool life of the TNMG160404 AH8015 insert.

Can the insert be used for both internal and external turning?
Yes; the combination of form, chipbreaker and geometry makes the insert suitable for both external and internal turning, provided the selected holder and process parameters match the application.

How many cutting edges are available per insert?
The insert is double‑sided; each face can be indexed, increasing the number of usable cutting edges and improving cost efficiency per edge.
