TUNGALOY CCMT09T308-24 NS9530
Durable Finishing | NS9530 Premium Cermet | 0.8mm Radius for Strength
Product Overview
The Tungaloy CCMT09T308-24 NS9530 is a world-class Cermet turning insert designed for high-efficiency finishing and semi-finishing of steel. Featuring a 0.8mm corner radius, this model offers enhanced edge strength and higher feed capabilities compared to smaller radii, making it ideal for stable CNC machining. The NS9530 Cermet grade provides extreme chemical stability, preventing built-up edge and ensuring a brilliant mirror finish. Equipped with the 24-style chipbreaker, it delivers superior chip control and reliable tool life in precision machining applications. Made in Japan, this indexable turning tool is the professional choice for demanding production environments.

NS9530 Cermet Grade: Ultimate Chemical Stability
The NS9530 grade is a titanium-based Cermet known for its exceptional resistance to oxidation and wear. In precision machining, this allows for high-speed finishing while maintaining a razor-sharp edge. Because cermet has a low affinity for steel, it effectively eliminates Built-Up Edge (BUE), resulting in an unmatched mirror finish and long-term dimensional accuracy.
The 24 Chipbreaker Advantage
This indexable turning tool features the 24 chipbreaker, a geometry specifically ground for light-to-medium finishing. It ensures stable chip evacuation at higher feed rates, protecting the part surface from scratches and bird-nesting.
Recommended Cutting Parameters
Optimized for P (Steel) and K (Cast Iron) Finishing:
-
Cutting Speed (Vc): 120 - 280 m/min (390 - 920 SFM)
-
Feed Rate (f): 0.08 - 0.25 mm/rev (Enhanced by 0.8mm radius)
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro Tip: For the best surface gloss, increase your cutting speed while maintaining a stable setup.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Incredible Edge Strength" - Markus H., Germany
"The 0.8mm radius is much tougher than the 0.4mm for my finishing work. The NS9530 cermet gives a ground-like shine."
⭐⭐⭐⭐⭐ "Perfect for High-Volume CNC" - Kenji S., Japan
"Consistent results every time. Tungaloy quality is unbeatable for precision finishing on steel."
⭐⭐⭐⭐ "Durable Tool Life" - Sarah J., USA
"Ran these on alloy steel all day. Dimensional stability is excellent and the 24 chipbreaker keeps the chips clean."
⭐⭐⭐⭐⭐ "Mirror Finish Success" - Luigi P., Italy
"Exactly what I needed for our final pass operations. Great surface Ra values consistently."
⭐⭐⭐⭐⭐ "Fast Shipping & Genuine" - David R., Australia
"Authentic Tungaloy inserts. Arrived quickly and performed better than expected on our CNC lathes."
Technical Q&A
Q: Why use a 0.8mm radius (CCMT09T308) for finishing?
A: A 0.8mm radius provides better edge strength and allows for slightly higher feed rates compared to a 0.4mm radius while still achieving a fine finish.
Q: Is NS9530 suitable for Stainless Steel?
A: Cermet is optimized for carbon and alloy steels. For heavy stainless steel work, we recommend Tungaloy's PVD carbide grades like AH725.
Q: What tool holder fits this insert?
A: It fits any standard **SCLCR09** or **SCLCR3/8** turning tool holder or boring bar designed for size 09T3 inserts.
Expert Machining Tip: Why choose Cermet?
For precision machining, Cermet is the ultimate choice for the final pass. Unlike carbide, NS9530 Cermet maintains its sharp edge under high-heat finishing conditions, delivering that professional mirror finish your customers demand.
