CNMG120416 AH8015 Turning Insert for Turning (PVD‑coated carbide, 80° rhombic) — Tungaloy

A CNMG120416 AH8015 ISO turning insert designed for reliable external and internal turning, offering balanced wear resistance and edge stability for heat‑resistant alloys

• PVD-coated carbide grade AH8015
• ISO CNMG 120416 form, 80° rhombic
• Double-sided chipbreaker, cylindrical hole
• 1.6 mm corner radius for robust finishing

Reliable performance for heat‑resistant alloys

The combination of a PVD-coated carbide substrate and the AH8015 grade provides a well‑balanced compromise between wear resistance and edge stability, which is especially valuable when machining heat‑resistant alloys. A stable cutting edge reduces flank wear and helps maintain dimensional accuracy over longer tool life, resulting in fewer indexings and steady part quality. Explaining the benefit in practical terms: higher retention of the nominal geometry means more predictable process windows and less frequent intervention during production.

Controlled chips and steady metal removal

The integrated double-sided chipbreaker controls chip formation across a range of cutting conditions, improving evacuation and reducing the risk of entanglement in deeper cuts. The 1.6 mm corner radius increases edge strength and supports interrupted cuts and heavier feed rates without premature edge chipping. For operators, this means more consistent surface finish and a lower rate of unexpected tool changes, which in turn supports uninterrupted production and better overall efficiency.

Simple integration into ISO tooling systems

As an ISO-standard CNMG120416 insert, compatibility with holders is determined by form, relief angle, tolerance class, clamping method, size and thickness. The insert’s 80° rhombic geometry and the 0° relief angle simplify orientation in conventional external holders and adapting it to boring bars for internal turning. Specifying matching clamping components and checking the tolerance class ensures repeatable seating and secure fixation, which directly affects cutting stability and part repeatability.

Practical selection and process guidance

This turning plate is intended as a first choice for general machining of high‑temperature alloys: select the AH8015 grade and the double-sided geometry when a balance between productive metal removal and tool life is required. Choose the chipbreaker variant to match material ductility and machine stability; for less stable setups, a more conservative feed or smaller corner radius may be preferable. The ISO plate’s reversibility and standard form support cost efficiency by offering multiple cutting edges before disposal.

FAQ

Which materials are best processed with this insert?
The CNMG120416 AH8015 turning insert is optimised for heat‑resistant alloys and is suitable for general turning of alloys that demand a balance between wear resistance and edge stability.

How is holder compatibility ensured for this insert?
Compatibility depends on the insert form, relief angle (0°), tolerance class, clamping method, size (12 mm) and thickness (4.76 mm); checking these parameters against the chosen holder ensures secure seating for the CNMG120416 geometry.

What distinguishes the AH8015 grade?
AH8015 is a PVD‑coated carbide grade tailored to provide a compromise between wear resistance and cutting edge stability, making it a versatile choice for challenging turning tasks.

Is the insert indexable and how many edges are available?
The insert is double‑sided with a reversible design, providing multiple cutting edges before replacement and improving cost efficiency per edge.

Why does the corner radius matter in turning?
A 1.6 mm corner radius increases edge robustness, supports interrupted cuts and generally improves surface finish under stable cutting conditions, while also influencing recommended feed rates.
