TNMG 110412 AH8015 Tungaloy – ISO turning insert for external and internal turning

A TNMG110412 AH8015 turning insert for ISO-indexed external and internal turning, designed for general machining of heat-resistant alloys.

• PVD-coated carbide grade AH8015
• 60° triangular ISO form, 11 mm inscribed circle
• Double-sided chipbreaker and cylindrical hole
• Balanced wear resistance and cutting-edge stability

High productivity through material and coating

The combination of a PVD-coated carbide substrate and the AH8015 grade provides a reliable balance between wear resistance and edge stability, making this insert suited to demanding turning tasks on heat-resistant alloys and other difficult-to-machine materials. The coating reduces flank and crater wear under elevated temperatures, extending tool life and reducing downtime. The result is a measurable improvement in process economy through fewer tool changes and more stable batch production.

Consistent chip control and secure clamping

Equipped with a double-sided chipbreaker and a cylindrical centre hole, the insert delivers predictable chip formation for both light and moderate cutting depths. The triangle geometry with a 60° cutting angle and a 1.2 mm corner radius supports robust engagement in roughing and finishing passes. Compatibility with ISO-indexed toolholders is determined by insert form, relief angle, tolerance class, fixing method, size and thickness, so the component integrates smoothly into standard turning systems for reproducible results.

Clear dimensions for process planning

Key dimensions such as the 11 mm inscribed circle, 4.76 mm thickness and 1.2 mm corner radius allow straightforward incorporation into machining simulations and fixture set-ups. The 0° relief angle and the ISO-standard shape simplify orientation and seating in most external holders and boring bars. These measurable values help technicians select cutting parameters with confidence, reducing trial-and-error and shortening set-up times at the machine.

Versatile application and selection guidance

The grade selection of AH8015 makes this insert a first choice for the general machining of heat-resistant alloys, offering a compromise between longevity and edge robustness. For external turning, internal profiling or interrupted cuts, selecting the appropriate chipbreaker and matching the insert to a suitable holder will deliver the intended surface finish and dimensional stability. Where assistance is required in choosing the correct holder or cutting data, Metav Werkzeuge provides technical consultation to align tool choice with component tolerances and machine capability.

FAQ

Which materials is this insert best suited for?
The TNMG110412 AH8015 Tungaloy turning insert (SKU: 6947401-Tungaloy) is designed primarily for the general machining of heat-resistant alloys, offering a balance of wear resistance and edge stability for demanding applications.

How is compatibility with holders determined?
Compatibility is defined by the insert form, relief angle, tolerance class, fixing method, size and thickness; the TNMG110412 shape, 0° relief and 11 mm inscribed circle match standard ISO-indexed turning holders.

Can the insert be used for both roughing and finishing?
Yes, the double-sided chipbreaker and 1.2 mm corner radius enable use across roughing and finishing passes, provided cutting parameters are adjusted to suit the machining task and workpiece material.

What are the benefits of the PVD coating on this grade?
The PVD coating on this carbide grade reduces adhesive and abrasive wear at elevated temperatures, improving tool life and maintaining cutting-edge integrity during continuous turning operations.

What are the key dimensions to consider when programming a job?
Important dimensions are the 11 mm inscribed circle, 4.76 mm thickness, 1.2 mm corner radius and 60° triangle geometry; these values are critical for holder selection and achieving the required tool offsets.
