TNMG160412 AH8015 turning indexable insert (Tungaloy) — PVD-coated carbide, 1.2 mm corner radius

TNMG160412 AH8015 is an ISO‑standard turning indexable insert designed for external and internal turning of heat‑resistant and difficult‑to‑machine alloys, combining stable edge behaviour with economical tool life

• ISO TNMG160412 form for broad holder compatibility
• PVD-coated carbide AH8015 for heat-resistant alloys
• 1.2 mm corner radius for robust cutting edges
• Double-sided chipbreaker with cylindrical hole for secure clamping

High‑performance grade and geometry for consistent metal removal

The insert is produced in PVD‑coated carbide (AH8015), a grade developed for the general machining of heat‑resistant alloys where a compromise between wear resistance and edge stability is essential. The 1.2 mm corner radius increases edge strength and dampens chatter during interrupted cuts, while the 60° included angle provides a versatile geometry for a wide range of turning tasks. These design choices reduce the frequency of edge changes and help maintain consistent component tolerances in series production.

System compatibility and efficient clamping for operational reliability

Built to the ISO‑TNMG160412 standard, the insert fits a wide selection of external holders and boring bars when the form, free angle, tolerance class, fastening method, size and thickness match. The double‑sided chipbreaker enables two cutting edges per index, improving cost efficiency, and the cylindrical hole secures the insert against rotation in the pocket. Specifying the correct holder geometry and clamping set ensures repeatable positioning and minimises setup time, contributing to smoother process flows on the shop floor.

Practical advantages in machining and tool selection guidance

For turning operations the balanced properties of this grade enhance tool life without sacrificing surface finish quality; predictable chip control and stable cutting behaviour reduce machine downtime and rework. When selecting tooling, pair the insert with a holder that matches the stated free angle and tolerance class and choose a chipbreaker and grade tailored to the specific workpiece material and machining stability. Spare screws, backing pads and clamping kits compatible with ISO TNMG inserts secure long‑term productivity and simplify inventory management.

FAQ

What materials is this insert suitable for?
The TNMG160412 AH8015 Tungaloy indexable insert is optimised for heat‑resistant alloys and similar difficult‑to‑machine materials thanks to its PVD‑coated carbide composition and balanced wear/edge stability.

How does the 1.2 mm corner radius affect performance?
A 1.2 mm corner radius increases edge robustness and vibration damping, resulting in longer edge life and more consistent surface finishes when using the TNMG160412 AH8015 grade.

Is this insert reversible and how many usable edges does it have?
The insert is double‑sided with a chipbreaker on each face, offering two usable cutting edges per side depending on indexing practice and holder compatibility.

Which holder characteristics must be matched for reliable use?
Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness; selecting a holder specified for ISO TNMG160412 ensures secure clamping and correct seating.

Does the insert require a specific clamping screw or backing pad?
Use the correct clamping set and spare screws recommended for ISO TNMG inserts; Metav Werkzeuge can advise on the suitable components to ensure proper fixation and repeatability.
