CNMG120408 AH8015 turning insert by Tungaloy — PVD-coated carbide, rhombic 80° for turning

The CNMG120408 AH8015 is an ISO-standard rhombic turning insert designed for general turning of heat-resistant alloys, offering a balanced combination of wear resistance and cutting-edge stability suitable for demanding machining tasks.

• PVD-coated carbide AH8015 for heat-resistant alloys
• Rhombic CNMG form, 80° cutting geometry
• Double-sided insert with cylindrical hole
• Corner radius 0.8 mm for versatile turning

Consistent cutting performance for heat-resistant alloys

The PVD-coated grade AH8015 is tuned for applications where temperature and abrasion are critical. With a PVD-coated surface over a wear-resistant carbide substrate, the insert delivers longer tool life under thermal load while maintaining a sharp profile. The design reduces flank wear and helps to preserve edge stability, which translates into fewer tool changes and more predictable process windows when machining heat-resistant alloys.

ISO compatibility for quick system integration

As an ISO-standard CNMG insert, the geometry and tolerance class support straightforward integration into existing toolholders and boring bars. The rhombic form with an 80° included angle offers good engagement for both external and internal turning, while the cylindrical hole enables secure clamping with standard screws and clamping sets. This compatibility shortens setup times and streamlines inventory management across turning operations.

Economic efficiency through reversible use and robust design

The double-sided construction and robust substrate allow two effective cutting edges per indexation, lowering cost per edge and improving return on tooling. The insert’s stability and coating reduce unplanned downtime and contribute to predictable tool life, supporting higher productivity and lower total machining costs. The balance between wear resistance and cutting-edge robustness makes this an efficient choice for batch production and continuous manufacturing environments.

Practical machining guidance for optimised results

The geometry and dimensions — including a corner radius 0.8 mm and 4.76 mm thickness — make the insert suitable for a wide range of turning tasks where moderate radii and stable cutting conditions are required. Select the matching chipbreaker type and grade according to workpiece material and machine stability to obtain clean chips and reduced vibration. The form and relief angle ensure reliable performance when paired with appropriate holders and clamping hardware in both roughing and finishing passes.
