TNMG 160404 AH8015 — ISO indexable turning insert, PVD‑coated carbide by Tungaloy

The TNMG160404 AH8015 is an ISO‑compliant triangular indexable insert for turning, optimised for machining heat‑resistant alloys and general external and internal turning operations.

• ISO‑standard triangular insert, 60° geometry
• PVD‑coated carbide grade AH8015
• 0.4 mm corner radius for precision finishes
• Double‑sided chipbreaker, cylindrical hole

Consistent wear resistance for demanding alloys

The insert’s PVD‑coated carbide grade AH8015 delivers a balanced combination of wear resistance and cutting‑edge stability, making it suitable as a first choice for the general machining of heat‑resistant alloys. The coating reduces adhesion and thermal deformation at elevated cutting temperatures, which helps maintain tool life and reduces the frequency of tool changes. The result is a more predictable process and improved machine utilisation, which supports a cost‑efficient production flow.

ISO compatibility that simplifies holder selection

Designed to the ISO turning insert system, the triangular format with 60° angle, 16 mm inscribed circle and 4.76 mm thickness ensures straightforward compatibility with appropriate external holders and boring bars. Compatibility depends on matching the insert form, clearance angle, tolerance class, clamping method, size and thickness; the insert’s cylindrical hole and standard dimensions make it easy to source the correct holder or clamping set. Using a correctly matched toolholder preserves the intended cutting geometry and helps achieve repeatable results on the lathe.

Reliable chip control and improved process stability

The double‑sided chipbreaker design and 0.4 mm corner radius support stable chip formation and consistent surface integrity in light to moderate finishing passes. Stable chips reduce the risk of rework and machine downtime while the reversible nature of the insert offers economical use of both cutting edges. Taken together, these features improve operator confidence at the machine and contribute to more predictable cycle times when turning challenging materials.

FAQ

Which materials is this insert designed for?
The AH8015 grade is specified for the general machining of heat‑resistant alloys; the TNMG160404 insert from Tungaloy performs well where a balance of wear resistance and edge stability is required.

How does one ensure the insert fits an existing holder?
Compatibility depends on matching the insert form, clearance angle, tolerance, clamping method, size (16) and thickness (4.76 mm); confirm the holder accepts TNMG‑format triangular inserts with a cylindrical hole.

Can this insert be used for finishing operations?
Yes. The 0.4 mm corner radius and the chipbreaker geometry support precision finishes when combined with appropriate feeds, speeds and a stable workholding setup.

Is the insert reversible and how many cutting edges are available?
The TNMG160404 is double‑sided and reversible, providing multiple usable cutting edges for economical tool use; the chipbreaker is designed for consistent chip control on both sides.

What are the key geometric features to note?
Triangular shape with a 60° included angle, cylindrical hole for clamping, 4.76 mm thickness and a 0° relief angle, which together define the mechanical and cutting‑geometry requirements for holder selection.
