CNMG120404 AH8015 ISO turning insert (rhombic, PVD-coated) by Tungaloy

CNMG120404 AH8015 is an ISO‑standard rhombic indexable insert designed for external and internal turning of heat‑resistant alloys and general turning applications

• PVD-coated carbide grade AH8015
• Rhombic insert, 80° included angle
• Double-sided chipbreaker for stability
• ISO-standard compatible with holders

Consistent cutting performance for demanding alloys

The CNMG120404 AH8015 is manufactured from carbide with a PVD coating and a grade tailored for heat‑resistant alloys. This combination provides a balance between wear resistance and cutting-edge stability, which reduces downtime due to unexpected tool failure and helps maintain consistent component tolerances. The PVD layer improves surface hardness and reduces adhesion, so the insert resists built‑up edge when machining higher temperature materials; as a result, tool life is extended and process reproducibility is enhanced.

System compatibility that simplifies tool selection

Compatibility with toolholders is defined by geometry, relief angle, tolerance class, fastening method, overall size and thickness. The rhombic plate format with a cylindrical mounting hole and a declared 80° included angle permits robust engagement for general turning, while the specified 0° relief provides a neutral clearance suited to many external and internal operations. The insert is part of an ISO insert system that requires a matching holder, shim/clamp set and fastening screws; selecting the correct combination ensures repeatable clamping and optimal cutting conditions.

Productivity improvements through stable edge control

The double-sided chipbreaker design allows indexable use of both cutting edges, effectively doubling available cutting positions and improving overall economy. The AH8015 grade is described as a first choice for the general machining of heat‑resistant alloys, offering a pragmatic compromise between longevity and edge strength. For production environments where consistent surface finish and dimensional control matter, this insert supports higher process security and predictable wear progression when paired with stable machining parameters and the appropriate chip control geometry.

FAQ

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

How is compatibility with a toolholder determined?
Compatibility depends on insert form, relief angle, tolerance class, fastening type, size and thickness; the CNMG120404 requires an ISO‑compatible holder, appropriate shim/clamp set and the correct fastening screw.

What benefits does the PVD coating provide?
The PVD coating increases surface hardness, improves wear resistance and reduces adhesion, which helps to limit built‑up edge and extend the useful life of the carbide cutting edge.

Is the insert indexable and does it support multiple cutting edges?
Yes, the double‑sided chipbreaker enables indexing of both sides, providing multiple usable cutting edges and improved process economy.

What do the 80° included angle and 0° relief mean in practice?
An 80° included angle gives a robust engagement suitable for general turning, while a 0° relief denotes a neutral clearance geometry used in many external and internal turning operations for consistent cutting behaviour.
