Benefit from the combination of a PVD‑coated AH8015 grade for heat‑resistant alloys, an 80° approach angle and a 0.8 mm corner radius that together ensure stable cutting and reproducible parting results; order the insert directly via Metav Werkzeuge or contact our consultants for application support.

CPMT 120408 AH8015 indexable insert for Turning — 80° approach, PVD-coated (Tungaloy)

The CPMT120408 AH8015 is a rhombic indexable insert engineered for precise parting, grooving and stepover cutting in turning operations, optimised for use in the TungCut system family.

• PVD-coated carbide grade AH8015
• Rhombic insert, 12 mm size
• 80° approach angle for precise cutting
• Single-sided chipbreaker with centre hole

Reliable machining of heat‑resistant alloys and long tool life

The combination of the AH8015 grade and a thin PVD coating delivers an even balance between wear resistance and edge stability, making the insert particularly suited to turning tasks with heat‑resistant alloys. The coated carbide substrate reduces flank wear under elevated temperatures and maintains a sharp cutting edge for longer tool life. For production environments this translates into fewer index changes, more consistent component tolerances and improved process uptime.

Secure clamping and consistent chip control for repeatable results

A rhombic plate form with a 12 mm size, 4.76 mm thickness and a 0.8 mm corner radius provides predictable cutting geometry for fine parting and narrow groove work. The single-sided chipbreaker is designed to form controllable chips on expected feed ranges, while the cylindrical hole with a one‑sided countersink (40°–60°) ensures firm seating and minimal micro‑movement in the pocket. These features reduce vibration and support repeatable surface finish and dimensional accuracy in series production.

System compatibility and operational flexibility with TungCut

As part of the TungCut system family, the insert integrates with dedicated holders, clamps and stechplates to simplify set‑up and changeover. The combination of the 80° approach angle and the insert geometry allows operators to adjust cutting width and depth efficiently, covering external and internal parting, as well as standard grooving tasks. The system orientation supports cost‑effective machining by enabling straightforward inventory management and fast replacement cycles.

FAQ

Is this insert suitable for machining heat‑resistant alloys?
The CPMT120408 AH8015 insert from Tungaloy is designed for general machining of heat‑resistant alloys; the AH8015 PVD grade provides an effective compromise between wear resistance and cutting edge robustness for turning and parting tasks.

Which holders and clamps are compatible with this geometry?
The insert matches TungCut system holders and clamp elements made for CPMT120408 geometry; ensure the toolholder accepts a 12 mm rhombic plate with a central hole and 80° approach for correct seating.

How does the chipbreaker influence chip formation?
The single‑sided chipbreaker on this insert promotes predictable chip shapes at the intended feeds, aiding evacuation in parting and narrow‑groove operations and contributing to consistent surface quality.

What clamping considerations apply to the countersunk hole?
The cylindrical hole with one‑sided countersink (40°–60°) is intended for secure clamping in the TungCut pocket; correct clamp selection prevents tilt and ensures repeatable cutting performance with the CPMT120408 AH8015.

Can the insert be used for both external and internal grooving?
Yes — the geometry and grade are suitable for external and internal parting and grooving within the capabilities of the chosen holder and machine setup, offering flexibility across several turning applications.
