CNMG120404 AT9530 CNMG 120404 turning insert — Tungaloy, coated cermet, finishing focus

The CNMG120404 AT9530 is an ISO‑standard rhombic indexable insert intended for finishing and light turning of Stahl components, designed to deliver consistent surface quality and predictable wear behaviour.

• Coated cermet grade AT9530
• Designed for finishing and light turning
• Rhombic CNMG geometry, 0° rake angle
• Double-sided chipbreaker, with central hole

Superior surface quality for finishing cycles

The insert is engineered for fine finishing operations, where surface finish and dimensional consistency matter. The coated cermet composition AT9530 promotes low and even flank wear during low‑to‑medium cutting forces, which helps to reduce rework and minimise downstream polishing. Its small 0.4 mm corner radius and optimised geometry support stable contact with the workpiece, enabling a high‑quality finish in internal and external turning operations on Stahl.

Reliable chip control and simplified clamping

A double‑sided chipbreaker combined with a cylindrical central hole ensures secure seating and predictable chip formation. The rhombic CNMG silhouette and standard ISO interface allow straightforward matching to compatible toolholders; compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness. When mounted with the correct holder and clamp set, the insert provides consistent cutting behaviour and repeatable results across batches.

Productivity gains through material and design

The AT9530 grade focuses on finishing and light machining, balancing wear resistance with toughness to maintain edge integrity. The insert’s 4.76 mm thickness and 12 mm inscribed circle support sufficient edge life for high‑quality finishing passes while remaining economical in use. For shops seeking predictable process stability, this indexable insert reduces downtime related to edge failure and supports smoother production flow in precision turning tasks.
