CNMG120412 AH8015 Tungaloy turning insert (ISO), PVD-coated carbide, 80°

CNMG120412 AH8015 is a rhombic ISO turning insert designed for external and internal turning applications, providing a balanced combination of wear resistance and edge stability for machining heat-resistant alloys.

• PVD-coated carbide AH8015
• Rhombic insert, 80° cutting angle
• 1.2 mm corner radius
• Double-sided chipbreaker
• Cylindrical hole for secure clamping

Stable integration and predictable tool life for turning operations

The ISO-standard geometry ensures straightforward compatibility with ISO holders when form, clearance angle, tolerance class, fixing method, size and thickness match. The PVD-coated carbide grade AH8015 is engineered as a first-choice grade for general machining of heat-resistant alloys, offering a balanced combination of wear resistance and edge stability that extends effective tool life. For process planners, this means fewer tool changes and more consistent cycle times without compromising surface quality.

Reliable chip control and improved surface finish on critical components

An 80° rhombic geometry paired with a 1.2 mm corner radius increases cutting edge strength and stiffness, which benefits interrupted cuts and heavier depths of cut. The double-sided chipbreaker is optimised for reliable chip formation and evacuation, reducing the risk of built-up edge and improving repeatable surface finishes. For technicians less familiar with insert geometry: a larger corner radius distributes cutting forces over a longer edge, improving stability, while the chipbreaker grooves control chip curl and breakage for safer automatic evacuation.

Application versatility and straightforward process advice

The insert is suited to external and internal turning of heat-resistant and difficult-to-machine alloys where a combination of edge stability and wear resistance is required. Its cylindrical locating hole and standard thickness simplify clamping and replacement in indexed toolholders, reducing setup time and inventory complexity. For production teams seeking to improve throughput and reduce interruptions, this insert supports a productive workflow through predictable cutting behaviour and consistent component quality. If additional machining data or holder recommendations are required, technical advice is available to match the insert to the specific machine and workpiece requirements.

FAQ

What materials is this insert suitable for?
The CNMG120412 AH8015 insert is intended primarily for heat-resistant alloys and offers a balanced performance for a wide range of steels and alloyed materials thanks to the PVD-coated carbide grade AH8015.

How does the 1.2 mm corner radius affect machining results?
A 1.2 mm corner radius increases edge strength and improves stability during turning, helping to reduce chatter and deliver more consistent surface finishes compared with smaller radii.

Is the insert compatible with standard CNMG holders?
Compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness; the CNMG120412 conforms to ISO dimensions but verification against the chosen holder is recommended.

What advantage does the double-sided chipbreaker provide?
The double-sided chipbreaker ensures reliable chip formation and breakage on both indexable faces, supporting consistent chip control and safer automatic chip evacuation in continuous production.

Can the insert be used for interrupted cuts or heavy roughing?
Yes, the 80° rhombic geometry combined with the 1.2 mm corner radius provides the stiffness and edge support needed for interrupted cuts and heavier roughing operations.
