CNMG 120404 NS9530 Tungaloy indexable insert for turning, finishing in steel

The CNMG120404 NS9530 Tungaloy insert is an ISO-standard, rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and a geometry suited to continuous cuts and small depths of cut.

• Finishing cermet grade NS9530
• Sharp cutting edge for low cutting forces
• ISO CNMG120404 shape with 80° geometry
• Double-sided chipbreaker with cylindrical hole

Exceptional surface quality through a finishing cermet

The uncoated cermet NS9530 is optimised for finishing cuts on steel, delivering a high surface finish with reduced cutting forces. The sharp edge geometry and low cutting resistance minimise vibration and thermal loading, which helps to produce consistent component appearance and tighter tolerances. For applications with continuous cutting and small depths of cut, this substrate provides improved stability compared with general-purpose grades and supports longer intervals between part rework.

Plug-and-play integration into ISO tooling systems

The CNMG format follows ISO standards, making compatibility dependent on insert form, 0° relief angle, tolerance class, clamping and thickness. The rhombic, 80° lead shape and the 4.76 mm plate thickness require a matching external holder or boring bar, plus the appropriate shim/clamping set and replacement screws. These system elements ensure accurate positioning and repeatable indexation, so the insert can be integrated into existing turning toolholders without extensive modification to the tooling system.

Economical finishing with controlled chip formation

Equipped with a double-sided chipbreaker, the insert supports manageable chip control during finishing, particularly on steels where continuous chips are expected. The combination of a stable cutting edge and the cermet substrate reduces cutting forces and can enhance tool life in steady-state finishing operations. This makes the insert a cost-effective choice where consistent part quality and predictable machining behaviour are priorities, especially in series production and precision workshops.

FAQ

What applications is this insert best suited for?
The CNMG120404 NS9530 insert is intended for finishing on steel; the uncoated cermet substrate and sharp cutting edge favour continuous cutting and small depths of cut for superior surface quality.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the CNMG120404 NS9530 promotes controlled chip formation in finishing operations, improving surface consistency and reducing the risk of entangling chips.

Is this insert compatible with existing ISO toolholders?
Compatibility depends on holder form, clamping method, tolerance class and the 4.76 mm plate thickness; the insert is ISO-standard, so matching external holders or boring bars and appropriate clamping sets are required.

Which materials can be machined with this grade?
The NS9530 cermet grade is optimised for machining steel in finishing operations, providing low cutting forces and good surface quality under continuous cutting conditions.
