CNMG120408 NS9530 ISO turning insert — finishing grade by Tungaloy

CNMG120408 NS9530 is a rhombic ISO turning insert designed for finishing operations in steel turning; compatible with standard CNMG holders and intended for continuous cuts and fine surface requirements.

• Uncoated cermet NS9530 for fine finishes
• Rhombic CNMG form ISO 120408
• 0.8 mm corner radius for smooth profiles
• Double-sided chipbreaker with cylindrical hole

Achieving consistent fine finishes with minimal cutting forces

The insert is manufactured as an uncoated cermet in the NS9530 grade, which is optimised for finishing in steel applications. The material combination gives a sharp cutting edge and low cutting forces, reducing vibration and enabling a more stable tool tip during light cuts. This advantage translates directly into fewer reworks and a faster path to final dimensional tolerance. The 0.8 mm corner radius supports fine profile control while limiting tool engagement, which helps maintain component surface integrity on long running batches.

System compatibility and secure clamping for repeatable results

Designed to ISO geometry, the ISO 120408 designation and the rhombic CNMG form ensure compatibility with a broad range of holders. Fit and clamping are determined by form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s double-sided chipbreaker and cylindrical hole provide reliable seating and quick index changes. The standardised dimensions and 4.76 mm plate thickness support predictable tool life and make spare stocking straightforward, reducing downtime in production environments.

Practical efficiency in workshop workflows

As a finishing-grade insert the cutting-edge quality delivers higher surface quality with smaller feeds and low depths of cut, particularly in continuous cutting conditions. The combination of the grade and geometry leads to improved process stability and less burr formation on turned components.

FAQ

What materials is the CNMG120408 NS9530 best suited for?
The CNMG120408 NS9530 insert is specified for finishing in steel; the NS9530 cermet grade provides the edge definition and low cutting forces suited to continuous turning of steel components.

How does the 0.8 mm radius affect surface quality?
A 0.8 mm corner radius on the CNMG120408 helps produce smoother surface profiles and reduces the tendency to form chatter marks when used with appropriate feeds and light depths of cut.

Is the insert compatible with standard CNMG holders?
Compatibility is ensured by the ISO geometry of the CNMG120408; correct selection depends on holder form, tolerance class, fastening and plate thickness to secure repeatable clamping.

What are the handling and indexing advantages of this insert?
The double-sided chipbreaker and cylindrical hole design of the CNMG120408 NS9530 allow simple indexing and stable seating, supporting rapid tool changes and reduced setup time.
