NS9530 Cermet: Excellence in Finishing
The NS9530 grade is a specialized titanium-based Cermet (Ceramic-Metal). Unlike standard tungsten carbide, Cermet provides a much higher level of chemical stability at high speeds, which prevents the workpiece material from sticking to the cutting edge (BUE). This long-tail keywords favorite ensures that your tool life remains consistent while achieving a spectacular mirror finish.
The 24 Chipbreaker Advantage
The 24-style chipbreaker is Tungaloy's versatile light-finishing geometry. It is engineered to break chips into small, manageable curls at low to medium feed rates, preventing scratches on the surface of your precision components and ensuring a smooth CNC machining process.
Recommended Cutting Parameters
Best for Steel (P) and Cast Iron (K) Finishing:
-
Cutting Speed (Vc): 130 - 280 m/min (425 - 920 SFM)
-
Feed Rate (f): 0.05 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro Tip: Higher spindle speeds are recommended for Cermet grades to maximize surface gloss.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Brilliant Finish" - Matthias K., Germany
"The NS9530 grade gives a finish that looks ground, not turned. Perfect for high-precision steel parts."

"Arrived fast. The CCMT09T3 size fits all our standard holders. NS9530 is unbeatable for cermet finishing."
Technical Q&A
Q: Can I use this for machining 304 Stainless Steel?
A: NS9530 is a Cermet optimized for carbon and alloy steels. For heavy stainless work, we recommend Tungaloy's PVD coated carbide grades like AH725.
Q: What tool holder fits this CCMT09T304?
A: It fits any standard **SCLCR09** or **SCLCR3/8** turning tool or boring bar designed for size 09T3 inserts.
Q: Why choose Cermet over Carbide for finishing?
A: Cermet has higher thermal stability and less affinity for steel, which prevents built-up edge and produces a much shinier surface finish than carbide.
Expert Machining Tip: Why Cermet?
For the best results in precision machining, use NS9530 Cermet to achieve a mirror finish. Unlike carbide, cermet maintains a sharp cutting edge at high speeds, making it the perfect indexable turning tool for finishing operations in CNC machining.
