CNMG120408 AT9530 — indexable turning insert for Turning, coated cermet, 0° clearance (Tungaloy)

CNMG120408 AT9530 is a coated cermet indexable insert designed for precision finishing and light turning of steel, offering repeatable edge life and improved surface quality

• Coated cermet grade AT9530
• ISO CNMG 120408 rhombic format
• 0.8 mm corner radius for fine finishes
• Double-sided chipbreaker, cylindrical hole

High-quality finishing and controlled wear for stable results

The coated cermet composition AT9530 focuses on surface finish and uniform wear in finishing and light‑cutting operations on steel. Cermet combines ceramic hardness with metal toughness to reduce built‑up edge and promote a fine surface without aggressive feed rates. The coating enhances oxidation resistance and lowers friction at the cutting edge, which leads to more consistent component quality and extended edge life compared with uncoated grades. For users seeking predictable batch output, this results in fewer part reworks and a steadier process window.

Geometry engineered for repeatability and clamp stability

A rhombic CNMG outline with an 80° included angle and a 0.8 mm corner radius gives a balanced edge for smooth finishes while still tolerating modest interruptions. The 0° clearance angle yields a neutral approach suitable for many holder geometries and lends itself to reliable seating in ISO‑compatible carriers. The insert’s cylindrical hole and standard thickness of 4.76 mm ensure secure clamping and accurate positioning, which reduces vibration and improves repeatability. The double‑sided design with integrated chipbreaker doubles available edges, cutting per‑edge cost and simplifying inventory handling.

ISO compatibility and economical tooling strategy

As an ISO‑standard CNMG120408 insert, compatibility with a wide range of external holders and boring bars is ensured when holder form, free angle, tolerance class, fastening and size match. The insert is intended for conventional turning setups and forms one part of an economical system: indexable insert, suitable holder, clamp set and replacement screws. The indexable concept minimises machine downtime for tool changes and, combined with the AT9530 wear characteristics, supports a cost‑effective finishing strategy that keeps throughput and surface quality aligned with production targets.

FAQ

What materials is this insert suited for?
The CNMG120408 AT9530 insert is optimised for steel finishing and light machining, where the cermet grade delivers improved surface quality and controlled wear.

How many usable edges are available per insert?
Due to the double‑sided chipbreaker design, the insert offers multiple indexable edges, which reduces tooling cost per edge and simplifies changeover.

What does the 0° clearance angle mean for clamping?
A 0° clearance angle provides a neutral approach suitable for many ISO holders; secure seating is achieved via the cylindrical hole and standard thickness to ensure stable clamping.

Is the insert compatible with standard CNMG holders?
Yes — the CNMG120408 format follows ISO standards; compatibility depends on matching holder form, free angle, tolerance and fastening.

How does the AT9530 cermet compare to conventional carbide grades?
AT9530 cermet focuses on surface finish and even wear in finishing operations; it typically reduces built‑up edge and improves part appearance compared with some conventional carbide grades.
