CNMG120402 NS9530 CNMG turning insert for turning – Tungaloy

The CNMG120402 NS9530 Tungaloy indexable insert is an ISO‑compliant rhomboid turning insert designed as a finishing grade for steel, offering a sharp cutting edge and stable performance in continuous cuts.

• Uncoated cermet NS9530 for finishing
• 0° relief angle for accurate profiles
• 0.2 mm corner radius for fine detail
• ISO rhomboid insert with cylindrical hole

Exceptional finishing performance with low cutting forces

The finishing grade is built on an uncoated cermet substrate that prioritises surface quality and edge stability. Thanks to the NS9530 formulation and the inherently sharp cutting geometry, the insert produces low cutting forces and a consistently fine surface, reducing the need for secondary finishing. Intended for continuous cuts and small depths of cut, this geometry is especially effective where visual and dimensional surface quality are critical. The cemented carbide backing ensures sufficient support for the cutting edge under finishing conditions.

Reliable fitment and straightforward toolholder compatibility

Compatibility with toolholders is defined by shape, relief angle, tolerance class, fixing method, size and thickness, and this insert follows ISO conventions to ease integration into existing tool systems. The 0° relief and the rhomboid form factor make it suitable for standard CNMG toolheads; the cylindrical hole supports secure clamping and repeatable positioning. For workshops seeking predictable set‑up and quick indexability, the standard geometry helps to reduce machine downtime and simplifies inventory management.

Application focus and material suitability for efficient machining

This turning grade is optimised for finishing operations in steel, delivering repeatable edge performance and a stable chipflow with its double‑sided chipbreaker design. The small 0.2 mm corner radius permits accurate profile reproduction and fine-detail turning, while the 4.76 mm plate thickness provides structural rigidity during light finishing cuts. Where consistent surface integrity and tight tolerances matter, the combination of uncoated cermet and ISO form leads to both visual and dimensional benefits that support downstream assembly and inspection processes.

FAQ

Is this insert suitable for finishing operations on steel?
The CNMG120402 NS9530 Tungaloy insert is specifically developed as a finishing grade for steel, offering a sharp edge, low cutting forces and high surface quality for continuous cuts and small depths of cut.

What is the corner radius and how does it affect the finish?
The corner radius is 0.2 mm; this small radius helps to reproduce fine profiles and achieve a superior surface finish while minimising deformation on thin sections.

Which holders are compatible with this ISO insert?
Compatibility follows ISO conventions: holders matching the CNMG form, plate size 12, thickness 4.76 mm, and a compatible clamping design for a cylindrical hole will provide reliable fitment.

Is the insert coated or uncoated?
This grade is an uncoated cermet (NS9530), optimised for finishing applications where a sharp, wear‑resistant cutting edge and excellent surface integrity are priorities.

What chip control can be expected with this insert?
The insert features a double‑sided chipbreaker designed to promote stable chip formation under continuous finishing cuts, improving process reliability and surface consistency.
