CNMG120404 AH8015 ISO turning insert, PVD‑coated (Tungaloy)

CNMG120404 AH8015 is an ISO‑standard turning insert suited to external and internal turning of heat‑resistant alloys, designed for robust edge life and predictable wear behaviour

• PVD‑coated carbide AH8015 for heat‑resistant alloys
• ISO CNMG120404 geometry, 80° rhombic shape
• Double‑sided chipbreaker for extended usage
• Fits standard ISO holders and boring bars

Consistent cutting performance for demanding turning

The PVD‑coated AH8015 grade combines wear resistance with edge stability, making it a practical choice for the general machining of heat‑resistant alloys. The ISO geometry provides an 80° rhombic profile that balances strength and accessibility: the cutting edge supports substantive depth of cut while the confidence in edge retention reduces unscheduled tool changes. For job shops and production lines requiring repeatable results, this geometry reduces set‑up variance and contributes to a steadier process window.

Predictable fitment and selection criteria for tool systems

Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the insert features a rhombic plate form with a 0° clearance angle, a 0.4 mm corner radius and 4.76 mm plate thickness. The presence of a cylindrical hole and a double‑sided chipbreaker enables reversible use and straightforward clamping in standard ISO toolholders. Select the chipbreaker and grade to match the workpiece material, machining strategy and machine rigidity for optimum component finish and tool life.

Practical gains: productivity, tool life and system integration

The balanced combination of coating and substrate in this carbide grade supports longer tool life and consistent surface quality, which in turn lowers tooling costs per component and reduces machine idle time. The insert integrates into a simple system comprising a matching external holder or boring bar, shim/clamp set and replacement screws, enabling quick replacement and minimal machine downtime. This pragmatic setup is suited to shops that prioritise throughput and repeatable quality in turning operations.

FAQ

What materials is this insert suited for?
The CNMG120404 AH8015 Tungaloy insert is recommended for machining heat‑resistant alloys; the AH8015 grade offers a balance of wear resistance and cutting‑edge robustness for general applications.

Can the insert be used for internal turning?
Yes. The insert’s rhombic ISO CNMG120404 form and 80° approach angle make it suitable for both external and internal turning when used with an appropriate boring bar.

How does the PVD coating affect performance?
The PVD coating on the AH8015 carbide improves resistance to abrasive wear and helps to maintain edge integrity, extending the service life of the insert during sustained turning operations.

What is the plate thickness and how does it influence clamping?
The plate thickness is 4.76 mm; this standard thickness ensures secure clamping in compatible ISO holders and supports stable cutting when combined with the correct shim and clamp set.

Is the insert reversible and how many cutting edges are available?
With a double‑sided chipbreaker and a central cylindrical hole for clamping, the insert provides reversible use, allowing multiple cutting edges per insert depending on the clamping arrangement and indexability.
