CNMG120404 AT9530 — Tungaloy turning insert for finishing and light steel turning, coated cermet, 0.4 mm radius

The CNMG120404 AT9530 is an ISO‑compliant rhombic turning insert designed for finishing and light turning of steel where high surface quality and even wear are priorities

• ISO‑compliant rhombic turning insert
• AT9530 coated cermet for surface quality
• 0.4 mm corner radius for fine finishing
• Double‑sided chipbreaker for consistent cuts

Delivering a superior surface finish with prolonged edge life

The AT9530 grade is a coated cermet engineered for finishing and light machining of steel, offering a balance between hardness and toughness that promotes a consistently fine surface texture. The combination of the coating and substrate yields uniform wear, reducing the frequency of edge changes and the variability in part finish. For production environments where appearance and dimensional consistency matter, this behaviour supports fewer downstream operations and steadier process output.

Geometry and standards that ensure accurate, repeatable results

The rhombic geometry and 80° included angle deliver a stable cutting profile suitable for both external and internal turning. The insert’s 0° clearance angle and 0.4 mm corner radius provide controlled engagement with the workpiece, minimising vibration and improving dimensional predictability. As an ISO‑compliant insert, compatibility with standard holders is determined by form, clearance, tolerance class, fastening and thickness, which simplifies tool inventory and replacement in mixed‑brand toolrooms.

Built for process reliability and economical indexing

This indexable grade is double‑sided, offering multiple usable edges and economical re‑indexing during routine shifts. The insert thickness of 4.76 mm and a plate size of 12 mm contribute to stable clamping and reduced deflection in light machining operations. The presence of a cylindrical mounting hole supports secure locating on compatible toolblocks. Together, these features enhance process reliability and make the component a pragmatic choice for repetitive finishing tasks.

Practical application notes for efficient integration

Suitable primarily for external and internal turning of steel, the item performs best when the chipbreaker and grade selection align with the workpiece material, machining strategy and machine rigidity. The ISO insert fits into a system comprising a matching external holder or boring bar, a support/ clamping set and replacement screws. When machining priorities are surface quality and consistent tool life, this grade and geometry support stable cycles and predictable outcomes.

FAQ

What materials is this insert intended for?
The CNMG120404 AT9530 turning insert is specified for finishing and light machining of steel, with the AT9530 coated cermet prioritising surface quality and uniform wear.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm corner radius produces a smoother part surface and reduces stress concentration at the cutting edge, supporting high‑quality finishes on turned steel components.

Is the insert compatible with standard ISO holders?
Yes, the rhombic ISO designation and standard dimensions mean the insert is compatible with holders that match form, clearance, tolerance class, fastening, size and thickness.

How many cutting edges are usable per insert?
The double‑sided chipbreaker provides multiple usable edges for economical re‑indexing; actual edge count depends on the specific insert orientation and indexing practice.

What should be considered when selecting the chipbreaker and grade for a job?
Selection should be based on workpiece material, machining operation and machine stability; the AT9530 grade is optimised for finishing light steel operations where surface quality is key.
