Tungaloy CCMT060202-PS NS9530 Cermet Insert
Mirror Surface Finish | High-Speed Precision | Advanced NS9530 Grade
What makes NS9530 cermet the best for precision steel finishing?
The Tungaloy CCMT060202-PS NS9530 is a high-performance uncoated cermet turning insert engineered for exceptional surface quality and dimensional stability. The NS9530 grade is a premium cermet material that features a balanced combination of wear resistance and fracture toughness, specifically optimized for finishing steel and cast iron at high cutting speeds. This indexable turning tool utilizes the PS-style chipbreaker, which provides a sharp cutting edge and superior chip control for light depths of cut. With its 0.2mm corner radius, it is the ideal precision machining choice for small components and internal boring where low cutting force is essential. Made in Japan, this insert ensures a long tool life and reduces the need for secondary polishing in CNC machining workflows.

Why is the NS9530 cermet grade superior for high speeds?
The NS9530 grade is an advanced cermet (ceramic-metal composite) that offers high chemical stability and thermal resistance. Unlike traditional carbide, cermet has a very low affinity for steel, which virtually eliminates built-up edge (BUE) and ensures a polished surface finish. This long-tail keywords industry standard is perfect for precision machining in high-speed applications. For operators looking to improve tool life during long finishing cycles in CNC machining, NS9530 provides the necessary toughness to resist chipping while maintaining a razor-sharp cutting edge.
How does the PS chipbreaker handle finishing chips?
The PS Chipbreaker is a precision-ground geometry designed for light finishing tasks. Its sharp rake and narrow groove facilitate excellent chip breaking at very low feed rates and small depths of cut. This indexable turning tool is particularly effective in reducing radial cutting forces, preventing chatter and ensuring tight tolerances on thin-walled workpieces or during internal boring.
What are the recommended feeds and speeds for NS9530?
Recommended for P (Steel) and K (Cast Iron) finishing:
-
Cutting Speed (Vc): 100 - 350 m/min
-
Feed Rate (f): 0.03 - 0.12 mm/rev
-
Depth of Cut (ap): 0.1 - 1.0 mm
*Pro Tip: Higher cutting speeds with cermet will generally result in a superior surface finish. Ensure your setup is rigid.*
Real Feedback from Global Machinists

Machinist Support Q&A
Q: Can I use NS9530 for interrupted cuts?
A: Cermet is more brittle than carbide. While NS9530 has improved toughness, it is best suited for continuous finishing cuts. For heavy interruptions, consider a PVD carbide grade like AH725.
Q: Does this insert fit standard SCLCR holders?
A: Yes. It fits any standard **SCLCR06** or **SCLCR1/4** holder or boring bar designed for size 06 rhombic inserts.
Q: Is this insert uncoated?
A: Yes, NS9530 is a high-performance uncoated cermet grade. The material itself provides the necessary resistance to heat and wear without the need for additional coatings.
Expert Machining Tip: Why Cermet over Carbide?
When precision machining demands a mirror-like finish, Cermet (NS9530) is the superior choice. It maintains its edge sharpness at high temperatures where carbide begins to wear, resulting in a cleaner cut and longer tool life during high-speed finishing operations.
