CNMG 120412 AH8015 Tungaloy indexable insert for turning — PVD-coated carbide, 1.2 mm nose radius

A CNMG120412 AH8015 insert engineered for general external and internal turning, offering balanced wear resistance and cutting-edge stability for heat-resistant alloys.

• PVD-coated carbide grade AH8015
• ISO CNMG120412 rhombic insert
• Double-sided chipbreaker for flexibility
• 1.2 mm nose radius, 80° cutting angle

Consistent performance through PVD-coated carbide

The combination of a PVD-coated surface and the AH8015 carbide grade provides a reliable balance between wear resistance and edge stability. The PVD layer reduces adhesion and protects the cutting edge at elevated temperatures, which is why this insert is the recommended choice for the general machining of heat-resistant alloys. In practice, this leads to longer intervals between indexings and a more consistent surface finish on workpieces, supporting stable process parameters and predictable component quality.

Secure fit and ISO compatibility for straightforward tool integration

Designed to the ISO CNMG120412 form, the rhombic geometry with an 80° included angle and a 0° clearance angle ensures compatibility with a wide range of holders when form, tolerance class, fastening and thickness match. The insert’s cylindrical hole provides positive location and repeatable clamping, reducing seating play and vibration. This compatibility simplifies tool-room logistics and lowers the effort required to confirm correct seat and clamping for production batches.

Improved chip control and surface finish for higher productivity

A double-sided chipbreaker delivers flexible chip formation across different feed and depth conditions, enhancing chip evacuation and protecting the cutting edge. The 1.2 mm nose radius contributes to improved surface integrity and reduced scallop height during finishing passes, while the robust geometry supports heavier cuts where strength is needed. Together these features help increase productive cutting time and reduce non-productive tool changes, improving overall machining efficiency.

Application guidance and lifecycle considerations

Intended for turning operations, the insert is particularly suited to external and internal turning where material and stability demand a balanced grade. Selecting the correct chipbreaker and matching the insert grade to workpiece rigidity and cutting conditions will extend tool life and maintain output quality. For complex materials or mixed-production environments, plan inventory with the ISO designation and radius in mind to ensure fast replacements and minimal downtime.

FAQ

Which materials are suitable for this insert?

The CNMG120412 AH8015 insert is intended primarily for heat-resistant alloys and general turning applications; its AH8015 grade and PVD-coated carbide make it suitable where elevated temperature performance and balanced edge stability are required.

Is the insert compatible with standard CNMG holders?

Yes, the insert follows the ISO CNMG120412 geometry; compatibility depends on matching the holder’s form, clearance angle, tolerance class, fastening method, size and thickness to the insert specifications.

How does the double-sided chipbreaker affect productivity?

A double-sided chipbreaker provides flexible chip control and allows longer service intervals before indexing or replacement, which supports higher uptime and more consistent surface quality.

Does the cylindrical hole influence clamping reliability?

The cylindrical hole provides secure locating and repeatable clamping, minimising movement in the seat and improving process stability during turning operations.

What benefits does the 1.2 mm nose radius offer?

The 1.2 mm radius improves surface finish and increases cut strength at the tool tip, making it a practical choice for finishing passes and for applications where a balance between form accuracy and tool robustness is required.
