• ISO CNMG120404 rhombic indexable insert
• Double‑sided chipbreaker with cylindrical hole

Superior surface quality for steel finishing

The AT9530 grade is a coated cermet designed specifically for finishing and light machining of steel, emphasising a fine and consistent surface finish and uniform wear. Cermet combines ceramic and metallic bonding to deliver a harder, more wear‑resistant cutting edge than many conventional carbides, while the applied coating improves adhesion and thermal stability. The 0.4 mm corner radius helps to reduce cutting forces and supports a smoother transition on workpiece edges, which is particularly beneficial when producing high‑quality external or internal turned surfaces.

Reliable ISO compatibility and predictable machining

As an ISO‑standard insert in CNMG geometry, this indexable component integrates into standard turning systems where compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness. The CNMG form with an 80° included angle and 0° relief suits controlled finishing operations where stable contact and repeatability matter. Specifying an insert from an ISO series simplifies tool management on the shop floor and ensures known performance characteristics across different holders and clamping systems.

Economic operation through doubled indexing and controlled wear

The double‑sided design and integrated chipbreaker extend usable life and reduce tooling cost per part by enabling a quick index and re‑use of the second cutting edge. Predictable wear behaviour from the AT9530 grade reduces unscheduled tool changes and supports consistent batch quality. Complemented by a suitable holder, underlay and clamping set, this insert forms a system that reduces set‑up time and improves overall process reliability in production environments.

FAQ

What steels is this grade best suited for?
The CNMG120404 AT9530 Tungaloy insert is optimised for machining a broad range of steels, providing excellent surface finish and even wear during finishing and light turning operations.

How does the 0.4 mm corner radius affect part quality?
A 0.4 mm corner radius increases edge strength and smooths transitions on turned surfaces, helping to deliver consistent finishes and reducing the risk of chatter in most finishing applications.

Is the insert compatible with standard CNMG holders?
Compatibility depends on matching form, relief angle, tolerance class, fastening and thickness; when the holder meets ISO CNMG specifications, the insert will fit standard CNMG pockets.

Can this insert be re‑indexed and how many cutting edges are available?
The rhombic CNMG geometry is double‑sided, providing multiple cutting edges per index to extend life and reduce tooling costs through reuse.

What is the recommended use for the AT9530 coating?
The AT9530 coated cermet is recommended for finishing and light machining of steel, where surface quality and consistent wear are priorities.
