CNGG 120404 NS9530 indexable turning insert, rhombic 80° geometry — Tungaloy

CNGG 120404 NS9530 is an ISO‑standard indexable insert engineered for finishing turning of steel, offering a sharp edge and low cutting forces in continuous, light‑depth cuts

• Rhombic insert, 80° cutting geometry
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker, with hole

Achieve superior surface finish with lower machining forces

The combination of uncoated cermet grade NS9530 and a finely honed edge delivers a measurable improvement in surface quality during finishing passes. As a finishing grade for steel, the material promotes low cutting forces, which reduces tool‑holder vibrations and helps achieve consistent part tolerances. The small corner radius of 0.4 mm is designed for delicate profile work and tight radii, while the sharp edge geometry supports continuous cut conditions where surface integrity and dimensional accuracy are critical. This results in fewer rework operations and a more efficient production flow.

Seamless integration into ISO toolholder systems for reliable setup

Produced to ISO dimensions, the insert assures compatibility when the holder is matched by form, clearance, tolerance class, attachment method, size and thickness. The rhombic 80° geometry and 0° clearance angle allow straightforward seating in standard indexable turning holders and boring bars. The plate thickness of 4.76 mm and the standard 12 mm inscribed circle ensure predictable clamping behaviour and repeatable positioning. Clear reference to ISO conformity simplifies tool inventory management and reduces the time spent on tool selection and setup.

Controlled chips and practical features for finishing processes

The double‑sided chipbreaker improves chip formation in continuous cuts, aiding both process stability and surface finish. The insert is supplied with a cylindrical hole, enabling secure attachment and straightforward indexing; being double‑sided extends usable edge life before the insert must be replaced. Constructed from cemented carbide substrate and utilising a cermet grade, the insert is optimised for small depths of cut and steady feed conditions typical of fine turning operations, balancing tool life and finish quality without coated layers that can blunt a delicate edge.
