CNGG120404 NS9530 rhombic ISO turning insert, 0.4 mm radius — Tungaloy

The CNGG120404 NS9530 is an ISO rhombic indexable insert for external and internal turning, designed as a finishing grade for continuous cuts and small depths of cut.

*ISO rhombic insert CNGG120404
*NS9530 uncoated cermet finishing grade
*0.4 mm corner radius for fine surface finish
*Double-sided chipbreaker with cylindrical hole

Consistent finishing with low cutting forces

The insert is engineered as an uncoated cermet grade (NS9530) that delivers a sharp cutting edge and low cutting forces, which directly translates into improved machining stability during finishing operations. For turning applications this means fewer chatter issues and more consistent dimensional results, particularly when working with Stahl. The small 0.4 mm radius supports high-quality surface finishes on finishing passes while maintaining predictable tool life, reducing the need for frequent regrinding or replacement and contributing to overall productivity.

Reliable fit and stable clamping for repeatable results

Built to the ISO plate family, the insert’s rhombic geometry and 80° included angle ensure broad compatibility with common external holders and boring bars; compatibility is governed by form, clearance angle, tolerance class, attachment, size and thickness. The cylindrical hole and double-sided chipbreaker provide secure clamping and extended usable edges, which helps to lower tooling costs per component. With a plate thickness of 4.76 mm and standard ISO designation 120404, the component integrates into typical ISO-turning systems with minimal adaptation, ensuring repeatable set-ups and reduced machine downtime.

Practical guidance for efficient turning operations

This finishing grade insert is intended for continuous cuts and small depths of cut, making it suitable for fine external and internal profiling where surface integrity is critical. Select a holder and chipbreaker matched to the component material and stability of the set-up; the double-sided chip control assists in managing swarf to avoid surface damage and maintain cycle cleanliness. For uncertain material mixes or to optimise parameters for specific operations with Stahl, Metav Werkzeuge offers application advice to align insert grade, holder geometry and cutting data for best results.

FAQ

What types of turning tasks suit this insert best?
The CNGG120404 NS9530 insert is optimised for finishing operations in external and internal turning, delivering high surface quality and low cutting forces for continuous cuts.

Can this insert be used for different steel alloys?
Yes, the NS9530 grade is developed as a finishing sort for Stahl; selecting the correct chipbreaker and machining parameters is essential for best performance across different alloys.

How does the double-sided chipbreaker affect tool life?
The double-sided design provides additional usable edges and helps with chip control, which extends practical tool life and reduces replacement frequency for the insert.

Which holder features ensure correct compatibility?
Compatibility depends on form, clearance angle, tolerance class, attachment, size and thickness; ensure the holder matches the ISO form and the cylindrical hole clamping style of the insert.

Is the insert ready to fit standard ISO turning systems?
The insert follows ISO designation 120404 and fits standard ISO turning systems when paired with the appropriate holder, clamping set and screws.
