CNMG 120412 AH8015 indexable turning insert by Tungaloy — PVD‑coated carbide, rhombic form

The CNMG120412 AH8015 is an ISO‑standard rhombic indexable insert designed for external and internal turning, combining a sturdy 1.2 mm corner radius with a PVD‑coated carbide substrate for machining heat‑resistant alloys and general turning tasks.

• ISO CNMG geometry for universal turning
• PVD‑coated AH8015 carbide for heat‑resistant alloys
• Double‑sided chipbreaker, economical indexing
• Rhombic 12 mm plate, 1.2 mm corner radius

Consistent cutting performance with PVD‑coated AH8015

The PVD‑coated AH8015 grade provides a deliberate balance between wear resistance and cutting edge stability, making it particularly suited to the machining of heat‑resistant alloys and demanding general turning operations. A PVD (physical vapour deposition) coating forms a thin, hard layer on the carbide substrate that reduces adhesive wear and improves thermal resistance; this lowers flank wear rates under elevated temperatures and extends usable edge life. As a result, the insert delivers predictable tool behaviour across a range of workpiece materials, supporting stable process windows and consistent surface finish without resorting to frequent regrinds.

Reliable chip control and cost‑efficient indexing

Equipped with a double‑sided chipbreaker, the plate allows two cutting edges per face to be used, reducing cost per edge and simplifying tool management. The chipbreaker geometry promotes controlled chip formation and evacuation, which supports steady cutting forces and reduces the risk of built‑up edge. The central cylindrical hole and standard clamping form enable secure fastening in compatible holders, maintaining seating stability under interrupted cuts. The 1.2 mm corner radius strengthens the cutting edge, improving resistance to edge chipping and contributing to an even surface texture on the workpiece — a practical compromise between robustness and finish quality.

ISO compatibility and practical integration into turning systems

Built to the ISO CNMG 120412 specification, the insert features a rhombic plate form, 12 mm size and a nominal thickness of 4.76 mm, with a 0° clearance reference and an 80° cutting angle where applicable. Compatibility with a specific toolholder depends on the plate form, seating angle, tolerance class, fastening method, size and thickness; correct pairing with an appropriate external holder or boring bar plus the correct clamping set is essential for repeatable performance. The insert is part of a plug‑and‑play system: an ISO‑standard plate, the matching holder or boring bar, a suitable locating pad or clamp set and replacement screws form the complete assembly. For varied machining tasks, selecting the matching chipbreaker variant and the AH8015 grade ensures process reliability and optimised tool life.

FAQ

What materials is this insert best suited for?
The AH8015 grade of the CNMG120412 AH8015 insert is intended as a first choice for the general machining of heat‑resistant alloys, offering a compromise between wear resistance and edge stability.

Is the insert reversible and economical to use?
Yes, the CNMG120412 AH8015 insert is double‑sided with a chipbreaker design that enables economical indexing and extends the effective life per insert.

How is compatibility with toolholders ensured?
Compatibility depends on the ISO CNMG geometry, plate dimensions and clamping style; correct pairing of the plate with a matching external holder or boring bar, plus the appropriate clamp set and screws, ensures secure seating and reliable performance.

What benefit does the PVD coating provide?
The PVD coating on the AH8015 grade increases thermal resistance and reduces adhesive wear, which helps maintain cutting edge integrity during the turning of tougher alloys.

When should a 1.2 mm corner radius be selected?
A 1.2 mm corner radius offers greater edge strength for heavier cuts and intermittent conditions while still permitting a good surface finish; it suits operations where robustness and consistent finish are both required.
