CNMG 120404 AH8015 — ISO turning insert, 80° rhombic (Tungaloy)

A CNMG 120404 AH8015 indexable turning insert designed for external and internal turning of heat‑resistant alloys and general turning operations, compatible with ISO‑standard holders.

• PVD‑coated carbide grade AH8015
• ISO CNMG120404 rhombic insert
• Double‑sided chipbreaker for extended life
• Suitable for heat‑resistant alloys

High‑performance grade and coating for sustained machining

The AH8015 grade is a PVD‑coated carbide engineered as a first choice for machining heat‑resistant alloys, offering an effective compromise between wear resistance and cutting‑edge stability. The PVD layer increases resistance to abrasive and adhesive wear, which extends tool life under thermal load and reduces changeover frequency. For process planners, this translates to higher uptime and a lower cost per cutting edge while maintaining surface quality.

Geometry and clamping precision for repeatable results

The rhombic CNMG120404 geometry with an 80° included angle and a clearance angle of 0° provides a robust seat and reliable edge engagement in both external and internal turning. The insert is supplied with a cylindrical hole to ensure positive locating and ease of indexing on compatible clamping systems. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness, so matching to the correct ISO holder and shim/clamp set is essential for consistent, repeatable machining.

Dimensional design that supports surface finish and edge life

A thickness of 4.76 mm and a nominal size of 12 mm combined with a corner radius of 0.4 mm produce a compact, rigid insert suitable for a range of feeds and depths of cut. The double‑sided chipbreaker improves chip control across varying stability conditions, contributing to improved surface finish and reduced risk of edge chipping. The insert’s construction balances toughness and hardness so that, in stable setups, cutting performance and tool life are optimised.

Practical application guidance and system setup

The insert is intended for turning applications; selection of the correct chipbreaker and the AH8015 grade should be based on workpiece material, machining type and machine stability. The ISO‑standard format simplifies integration into established tool systems—typically an ISO‑compatible external holder or boring bar, a suitable shim or clamp, and matching screws. For specific setups, parameter recommendations and holder compatibility checks are available; the item is listed under SKU 6946759‑Tungaloy and manufacturer article number 6946759 for ordering and documentation purposes.

FAQ

What distinguishes the AH8015 grade from other grades?
The AH8015 grade is a PVD‑coated carbide formulated to balance wear resistance and edge stability, making the CNMG120404 AH8015 insert especially suitable for machining heat‑resistant alloys where thermal and abrasive demands are present.

Which workpiece materials are best suited to this insert?
The insert is intended primarily for heat‑resistant alloys and general turning applications; the PVD coating helps manage elevated temperatures and abrasive wear common with such materials.

How is holder compatibility determined for this insert?
Holder compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures the CNMG120404 AH8015 insert seats correctly and remains secure during machining.

Can the insert be indexed to use multiple cutting edges?
Yes — the rhombic CNMG geometry with a cylindrical hole and a double‑sided chipbreaker allows indexing to expose fresh cutting edges, reducing downtime and tooling costs.
