TNMG 160412 AH8015 ISO turning insert by Tungaloy — PVD-coated carbide, 60° triangle

TNMG 160412 AH8015 is an ISO-standard triangular turning insert designed for external and internal turning applications in demanding materials.

• ISO-standard TNMG insert for turning
• PVD-coated carbide for heat-resistant alloys
• Double-sided geometry with cylindrical hole
• Corner radius 1.2 mm for stable cutting edge

Higher productivity through balanced grade and coating

The combination of a PVD-coated surface and a modern carbide substrate gives this insert a reliable balance between wear resistance and edge stability, making it well suited to the general machining of heat-resistant alloys. PVD coating reduces adhesion and thermal softening at elevated cutting temperatures, which extends tool life and maintains consistent cutting forces. As a result, cycle times can be optimised and tool-change frequency reduced, supporting a smoother production flow and enhanced machine utilisation.

Secure clamping and ISO compatibility for repeatable results

The triangular shape with a central cylindrical hole and the ISO designation ensure compatibility with standard TNMG holders where form, relief angle, tolerance class, fastening method, size and thickness match. The 0° rake angle and 60° geometry support predictable chip formation and stable engagement in a variety of turning set-ups. Specified tolerances and the standardised format enable quick insert changes and repeatable positioning, which reduces setup time and improves dimensional consistency across batches.

Consistent surface finish from a defined cutting edge

The corner radius 1.2 mm delivers a robust cutting edge that resists chipping and helps produce a uniform surface finish on workpieces. Double-sided indexing permits economical use of both faces before replacement, while the plate thickness of 4.76 mm contributes to rigidity under radial and axial loads. When combined with an appropriate chipbreaker, the design helps control chip flow and minimises vibration, resulting in better surface integrity and reduced secondary finishing.

Application guidance and selection criteria

Designed primarily for turning, this grade is a practical first choice when machining heat-resistant alloys and similar demanding materials; select the AH8015 grade where a compromise between tool life and edge stability is required. Choose the chipbreaker geometry according to material, type of cut and machine stability: a more aggressive breaker for unstable setups, a finer breaker for finishing passes. For indexable insert systems, confirm holder compatibility by matching the ISO code, size (16), thickness (4.76 mm) and the insert’s hole style before ordering.

FAQ

What materials is this insert designed for? This TNMG160412 AH8015 insert from Tungaloy is primarily specified for the general machining of heat-resistant alloys, offering a balanced combination of wear resistance and edge stability.

Is the insert indexable and reversible? Yes, the insert is double-sided and indexable; the geometry supports turning operations on both faces until the defined wear limit is reached for economical utilisation.

How does the corner radius affect performance? A corner radius of 1.2 mm provides a sturdier cutting edge that reduces chipping risk and helps produce a consistent surface finish under moderate to heavy cutting conditions.

What should be checked for holder compatibility? Compatibility depends on matching the ISO code, form, relief angle, tolerance class, fastening method, size (16) and thickness (4.76 mm) between the insert and the toolholder.

Which chipbreaker should be chosen for finishing? Select a finer chipbreaker suited to finishing passes; choose a more pronounced breaker for roughing or when instability and chip control demand it.
