CNMG090408 NS9530 Tungaloy — Indexable Turning Insert, NS9530 Cermet, 0.8 mm Radius, 80°

CNMG090408 NS9530 Tungaloy is a precision finishing indexable insert designed for turning applications on steel and similar materials; rhombic form with a cylindrical hole ensures consistent clamping and repeatable results

• Precision finishing cermet grade NS9530
• Rhombic insert, 80° geometry
• 0.8 mm corner radius for fine edges
• Cylindrical-hole design for secure clamping

Consistent finishing performance with reduced cutting forces

The NS9530 grade is an uncoated cermet developed for finishing cuts on Stahl, offering a sharp cutting edge and low cutting forces that translate into improved surface quality and reduced tool-induced vibration. In practice, this means fewer reworks and a more predictable process when machining continuous cuts or taking light passes. The insert’s geometry contributes to a stable chip flow, while the hard, wear-resistant substrate provides consistent edge life under the expected finishing conditions. As a result, the component surface finish and tolerance adherence are improved without aggressive cutting parameters.

Compatibility and mounting for reliable production

Being ISO-standardised, the rhombic CNMG form matches a broad range of standard toolholders; compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness. The 80° cutting-angle geometry and 0° rake angle are well suited to general-purpose turning holders and boring bars that accept the CNMG family. The cylindrical hole ensures secure, repeatable clamping and straightforward replacement during tool changes. Specifying the correct holder and clamping components avoids slippage and maintains cutting-edge stability, which is vital for keeping cycle times consistent on small-batch and serial production alike.

Application focus and material suitability

This finishing grade is aimed primarily at turning operations on Stahl where surface integrity and dimensional accuracy are priorities. The insert is particularly effective for continuous cutting and small depths of cut, where its sharp edge and cermet substrate produce a superior surface without the need for coating. While optimised for finishing, the geometry and double-sided chipbreaker allow for economical tool use by presenting multiple cutting edges. Selecting the NS9530 grade will be advantageous where minimal work hardening and fine surface roughness are required.

Practical handling, productivity and process benefits

With a 0.8 mm corner radius the insert balances edge strength and fine-detail finishing, enabling closer tolerance control on fillets and small-diameter features. The uncoated cermet chemistry supports consistent edge retention during low-cutting-force finishes, reducing the frequency of edge changes and helping maintain uptime. Process planners benefit from the ISO conformity of the insert family: tool setup is straightforward, spare management is simplified and spare-part interchangeability supports lean workshop logistics. The result is a measurable improvement in process reliability and part-to-part consistency.

FAQ

What materials is this insert suited for?
The CNMG090408 NS9530 insert is a finishing grade optimised for turning Stahl and delivers high surface quality and low cutting forces when machining such materials.

Is the insert coated?
No; the CNMG090408 NS9530 is an uncoated cermet grade designed to provide a sharp edge and excellent surface finish in finishing operations.

Which holder types are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance, clamping method, size and thickness; the CNMG090408 conforms to ISO CNMG dimensions and fits standard CNMG holders and boring bars.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius offers a balance between edge strength and fine-surface capability, enabling closer tolerances on small features while maintaining acceptable edge life for finishing passes.

Are there multiple cutting edges available on the insert?
Yes; the double-sided chipbreaker design permits the use of multiple edges, improving economy by extending the number of indexable cutting edges per insert.
