CNMG 120404 NS9530 indexable turning insert — Tungaloy, rhombic, sharp finishing grade

CNMG 120404 NS9530 Tungaloy indexable insert for turning applications, designed for controlled, continuous finishing cuts on steels where a sharp edge and low cutting forces are required

• ISO‑standard rhombic form, 80° included angle
• Sharp uncoated cermet grade NS9530
• Double‑sided chipbreaker for consistent chips
• Compatible with standard CNMG holders

Consistent finishing performance through proven cermet technology

The CNMG geometry paired with the NS9530 cermet provides a sharp cutting edge and low cutting forces that favour surface finish and dimensional control. As a finishing grade, the uncoated cermet is optimised for continuous cuts and small depths of cut; this reduces built‑up edge formation and helps maintain a predictable tool life. The combination of rhombic 80° geometry and a 0.4 mm corner radius supports stable contact with the workpiece, producing repeatable smooth surfaces while keeping process forces modest.

Simple integration and demonstrable process reliability

Designed to the ISO series for turning inserts, the component fits into common CNMG carriers where holder form, clamping method and tolerance class match. The insert is double‑sided with a central cylindrical hole for secure fastening and economical indexability. A plate thickness of 4.76 mm and an inscribed circle of 12 mm provide robust seating and good heat dissipation during finish turning. Specifying this Tungaloy grade streamlines inventory and reduces changeover time while ensuring compatibility with established toolholders.

Material suitability and practical application benefits

The uncoated cermet NS9530 is intended for finishing steel grades and is particularly effective when cutting conditions favour continuous chip formation and low feed rates. The sharp edge reduces cutting resistance and the double‑sided chipbreaker supports consistent chip shape, both contributing to improved surface quality and reduced rework. For applications requiring fine finishes on turned components, this insert offers an efficient, repairable approach: index the insert as the edge wears to restore cutting geometry without full tool replacement.

FAQ

What cutting operations are suitable for this insert?
The CNMG 120404 NS9530 insert is intended for external and internal turning with a focus on finishing cuts; its sharp cermet edge and double‑sided chipbreaker suit continuous cuts on steel.

How is the insert fixed in the toolholder?
Fixing is by a central cylindrical hole and standard clamping systems for CNMG inserts; compatibility is determined by holder form, free angle, tolerance class, fastening method, size and thickness.

Can the NS9530 grade be used for interrupted cuts?
NS9530 is optimised for continuous finishing; interrupted cuts may reduce edge life compared with continuous turning, so assess stability and cutting conditions before use.

What are the main benefits of the uncoated cermet in this geometry?
The uncoated NS9530 offers a sharp cutting edge, low cutting forces and excellent surface finish in finishing applications, reducing the need for secondary polishing.

Is the insert indexable and economical for production runs?
Yes, the double‑sided CNMG120404 design enables indexability to restore cutting geometry quickly, supporting efficient tool use in series production.
