CNMG 120404 AH8015 indexable turning insert – PVD‑coated carbide, 0.4 mm corner radius (Tungaloy)

CNMG120404 AH8015 turning insert for general turning applications, designed for ISO‑compliant holders and adaptable to a wide range of workpiece materials

• ISO‑standard rhombic insert, size 12 mm
• PVD‑coated carbide grade AH8015
• Cylindrical hole for secure clamping
• Double‑sided chipbreaker

Reliable geometry for consistent turning performance

The rhombic ISO geometry delivers predictable cutting behaviour and straightforward seat compatibility with standard holders. The 80° included cutting angle and the 0° clearance contribute to stable tool engagement and repeatable results. Thanks to the rhombic form and the cylindrical hole the insert seats reliably in many clamping systems, reducing setup time and helping to maintain process stability on the shop floor. That reliability translates into fewer interruptions and a steadier production flow.

Balanced wear resistance and edge stability for demanding alloys

The PVD‑coated carbide AH8015 combines wear resistance with edge toughness, making the grade particularly suitable for the general machining of heat‑resistant alloys. The coating enhances surface hardness and reduces adhesion at the cutting edge, while the substrate maintains edge stability under variable cutting conditions. This balance supports longer effective tool life and fewer insert changes in mixed production environments where both durability and consistent finish matter.

Practical advantages in mounting and chip control

The insert’s cylindrical hole and standardised dimensions (size 12 mm, thickness 4.76 mm) simplify interchangeability across compatible external holders and boring bars. The double‑sided chipbreaker provides effective chip control for both directions of use, aiding evacuation in through‑cut operations and decreasing the likelihood of rework caused by poor chip formation. These design details support streamlined inventory management and faster changeovers at the machine.

Support for process selection and application flexibility

For turning, select a chipbreaker and the cutting parameters that match workpiece material, machine rigidity and depth of cut; the grade and geometry are intended as first‑choice options for many heat‑resistant and alloyed materials. Where high surface quality and repeatable tolerances are required, the combination of AH8015 grade and ISO geometry helps maintain dimensional consistency. When in doubt about the ideal chipbreaker or seat tolerance, consult process engineering data to align insert choice with production goals.
