CNMG120416 AH8015 ISO turning insert, PVD‑coated carbide — Tungaloy

CNMG120416 AH8015 ISO rhombic indexable insert for versatile external and internal turning in demanding alloy machining.

• ISO rhombic insert CNMG 120416
• PVD-coated carbide AH8015 grade
• Double-sided chipbreaker for stable chips
• Cylindrical hole for secure clamping

Durable grade for heat‑resistant alloy machining

The PVD-coated carbide composition of this indexable insert, identified by the AH8015 grade, is balanced for both wear resistance and cutting-edge stability. This composition makes it a reliable choice for general machining of heat‑resistant alloys where a compromise between tool life and edge strength is required. The coating reduces adhesive wear and helps maintain consistent cutting behaviour over extended cycles, which supports predictable tool-change intervals and improved machine uptime.

Geometry engineered for stable cutting and surface finish

The rhombic CNMG form with an 80° cutting angle and a 1.6 mm corner radius strengthens the insert for interrupted cuts and heavier engagement while still permitting reasonable surface finish. The 0° relief configuration provides a neutral geometry suited to a range of turning operations; the 4.76 mm thickness contributes to insert rigidity. These geometric parameters influence chip formation and cutting forces: a larger corner radius increases edge strength and reduces the tendency for edge chipping, while the neutral relief simplifies application across different set‑ups.

Chip control and clamping that enhance process security

Equipped with a double-sided chipbreaker, the insert promotes predictable chip fragmentation across many alloys and feeds, improving evacuation and reducing rework risk. The cylindrical hole and standard ISO form facilitate secure clamping in compatible holders, supporting repeatable positioning and consistent concentricity. Selection of the appropriate chipbreaker and grade should match the workpiece material, operation type and machine stability to ensure optimal cutting conditions and enhanced productivity.

System compatibility and practical application advice

This insert is part of the ISO turning insert system: correct compatibility with a toolholder depends on the insert form, relief angle, tolerance class, fastening method, size and thickness. Typical use covers both external and internal turning; the system build usually comprises an ISO insert, a suitable external holder or boring bar, a shim/clamp set and fastening screws. For adaptations or specific machining strategies, technical data such as corner radius, thickness and hole style determine suitability for a given set‑up — further machining parameter guidance is available on request via Metav Werkzeuge.

FAQ

What materials is this insert suitable for?
The CNMG120416 AH8015 Tungaloy indexable insert is engineered primarily for heat‑resistant alloys and general turning tasks; the AH8015 PVD‑coated carbide balances wear resistance and edge stability for a broad material range.

How does the 1.6 mm corner radius affect machining?
A 1.6 mm corner radius on the CNMG120416 insert increases edge strength and improves resistance to chipping, which is beneficial for interrupted cuts and heavier depths of cut while still supporting acceptable surface finish.

Is the insert reversible or single‑use per edge?
This rhombic CNMG insert is double‑sided with two usable cutting edges per side depending on wear; the double‑sided chipbreaker extends the usable life before indexing.

Which holder features must be checked for compatibility?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness — verify that the holder accepts CNMG form and 12 mm size with a 4.76 mm plate thickness and cylindrical hole clamping.

Can this insert be used for internal turning operations?
Yes — the geometry and neutral relief of this CNMG style, combined with the AH8015 grade, allow use in both external and internal turning applications when paired with a suitable boring bar or internal holder.
