TNMG 160408 AH8015 indexable insert for Turning — PVD-coated carbide (Tungaloy)

TNMG160408 AH8015 Tungaloy indexable insert is an ISO-standard triangular turning insert engineered for general external and internal turning of heat-resistant alloys and similar demanding materials

• ISO triangular insert, 60° included angle
• PVD-coated carbide grade AH8015
• 0° clearance angle for robust cutting
• Double-sided insert with cylindrical hole

Optimised cutting performance for heat-resistant alloys

The PVD-coated carbide grade AH8015 is formulated as a balanced choice between wear resistance and cutting-edge stability, making it suitable for the general machining of heat-resistant alloys. The coating increases surface hardness and reduces adhesive wear, which translates into longer periods between indexings and more consistent part quality. This balance supports higher uptime and improved process economy without demanding highly specialised operating conditions.

ISO compatibility and secure clamping for reliable results

As an ISO-standard insert, compatibility with the toolholder is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The triangular geometry with a 60° included angle and 0° clearance produces a robust cutting edge and predictable chip flow. The insert features a cylindrical mounting hole to match standard clamping systems; when used with a correctly matched external holder, the assembly delivers stable, repeatable performance. TNMG160408 can be indexed on both sides to maximise usable edge count.

Geometry and its effect on tool life and finish

The 0.8 mm corner radius provides a compromise between edge strength and surface quality: larger radii increase edge robustness and permit heavier cuts, while smaller radii favour finer surface finish. With a plate thickness of 4.76 mm and a nominal size of 16 mm, this insert yields mechanical stiffness in typical turning set-ups, reducing chatter risk and improving consistency of dimensional results. Understanding these geometric parameters helps to select feeds and depths of cut that match part tolerances and machine capability.

Practical guidance on chip control and application range

The insert is supplied with a double-sided chipbreaker configuration, allowing flexible chip control for a range of operations from roughing to light finishing. For external and internal turning, choose the chipbreaker and cutting data according to material family and component rigidity; a stable set-up and correct cutting fluid strategy will extend edge life and maintain surface integrity. The combination of grade and chipbreaker makes this insert a good general-purpose option when machining heat-resistant alloys and similar materials.

Economical use and shop-floor advantages

A double-sided triangular insert reduces tooling costs by offering multiple usable edges per index, while the robust PVD coating reduces frequency of tool changes. The ISO format simplifies stocking and replacement, and the insert integrates into the common system of insert, holder, clamping pad and securing screws. When combined with standardised holders and correct clamping, this geometry and grade support reproducible performance and lower total process cost over many production cycles.

FAQ

What materials is this insert best suited for?
The TNMG160408 AH8015 insert is optimised for the general machining of heat-resistant alloys, offering a blend of wear resistance and edge stability suitable for those materials.

How many cutting edges are available per insert?
The triangular, double-sided format provides multiple usable edges; the exact count depends on indexing practice but the geometry is designed to maximise edge reuse.

What does the 0.8 mm corner radius mean for machining?
A 0.8 mm corner radius increases edge strength compared with a smaller radius and supports heavier cuts while still delivering a good surface finish in many turning operations.

Is the insert compatible with standard ISO holders?
Yes, the ISO designation and cylindrical hole mean the insert is compatible with ISO-standard toolholders that match form, clearance angle, tolerance and fixing type.

What advantages does the PVD coating offer?
The PVD coating enhances surface hardness and reduces adhesive wear, helping to extend edge life and improve consistency under intermittent or continuous cutting conditions.
