CNMG120412 AH8015 CNMG turning insert for turning, PVD-coated carbide by Tungaloy

The CNMG120412 AH8015 is an ISO‑standard rhombic indexable insert designed for external and internal turning, especially suited to general machining of heat‑resistant alloys.

• PVD-coated carbide grade AH8015
• ISO rhombic 80° geometry
• 1.2 mm corner radius for steady cuts
• Double-sided chipbreaker, with hole

Robust grade for heat‑resistant alloy machining

The insert is made from PVD‑coated carbide in the AH8015 grade, selected as a first choice for the general machining of heat‑resistant alloys. The coating improves wear behaviour under elevated temperatures while the carbide substrate retains edge stability, which together reduce flank wear and maintain dimensional accuracy across longer tool life. This combination results in fewer tool changes and more consistent cycle times, supporting a measurable improvement in process efficiency.

Geometry and clamping that support stable cutting

With an ISO rhombic 80° cutting geometry and a 0° clearance, the insert gives a tried‑and‑tested rake and engagement suitable for a wide range of turning tasks. The 1.2 mm corner radius helps to absorb cutting forces, producing steadier cuts and improved surface finish when compared with very fine radii. The cylindrical hole and standard form ensure compatibility with ISO toolholders; correct matching of form, clearance, tolerance class, clamping and thickness is essential for secure seating and repeatable results.

Predictable chip control and economical handling

The double‑sided chipbreaker design supports reliable chip formation and evacuation across varying cut depths and feed rates, lowering the risk of built‑up edge and workpiece damage. As a reversible insert, it extends usable tool life through indexing, which reduces tooling consumption and inventory complexity in production environments. The overall result is a cost‑effective solution that maintains quality standards while simplifying logistics.

Practical notes on selection and use

The insert thickness of 4.76 mm and the rhombic shape make it versatile for both external and internal turning when the correct holder is used. Selection of chipbreaker pattern and grade should follow material type, machining operation and setup rigidity; the AH8015 grade balances wear resistance and edge stability, making it a good general‑purpose choice for many heat‑resistant materials. For optimal performance, match the insert to a holder specified for CNMG inserts and follow established clamping torque and seating procedures.
