Tungaloy CCMT060208-PS NS9530 Turning Insert
High-Stability Steel Finishing | Premium Cermet Grade | 0.8mm Radius for Edge Strength
How does the CCMT060208-PS NS9530 achieve a mirror finish on steel?
The Tungaloy CCMT060208-PS NS9530 is a high-performance uncoated cermet turning insert engineered for precision finishing and semi-finishing of steels. The NS9530 grade is a titanium-based cermet that provides an exceptional balance of wear resistance and fracture toughness. Unlike carbide, cermet has a very low chemical affinity for steel, which prevents built-up edge (BUE) and results in a polished, mirror-like surface. This indexable turning tool features the PS-style chipbreaker, a ground geometry that delivers excellent chip control at light to medium depths of cut. With a robust 0.8mm corner radius, this insert offers superior edge strength and stability, making it the perfect precision machining solution for high-speed CNC machining. Made in Japan, it ensures a consistent and long tool life for high-efficiency production.

Is NS9530 cermet durable enough for semi-finishing?
Yes, the NS9530 grade is specifically designed to be tougher than standard cermets, allowing it to handle light semi-finishing operations without chipping. This long-tail keywords industry favorite maintains exceptional edge sharpness at high speeds. In precision machining, the 0.8mm radius of the CCMT060208-PS provides a stronger cutting edge and allows for higher feed rates compared to 0.4mm inserts, all while ensuring an elite surface finish. This makes it a reliable choice for long-run CNC machining where dimensional stability is paramount.
The PS Chipbreaker: Ground for Stability
The PS Chipbreaker features a sharp rake angle and a ground top surface that significantly reduces cutting resistance. This is essential for preventing chatter in indexable turning tool applications. Even with a larger 0.8mm radius, the PS geometry ensures chips break cleanly, protecting the workpiece and ensuring the safety of the operation.
What are the recommended feeds and speeds for NS9530?
Ideal for P (Steel) and K (Cast Iron) finishing:
-
Cutting Speed (Vc): 100 - 320 m/min (High speed optimizes Cermet)
-
Feed Rate (f): 0.08 - 0.20 mm/rev
-
Depth of Cut (ap): 0.3 - 2.0 mm
*Tip: For the best surface finish, use the highest cutting speed your machine can safely handle.*
Feedback from Global Machining Experts
⭐⭐⭐⭐⭐ "Beautiful finish on 1045 steel" - Stefan H., Germany
"I used the 0.8mm radius version for semi-finishing shafts. The finish is fantastic and the tool life is very stable at 250 m/min."
⭐⭐⭐⭐⭐ "Great for CNC production" - Akio T., Japan
"Genuine Tungaloy NS9530. We run these on our Nakamura lathes. The dimensional accuracy stays within 0.01mm for hours."
⭐⭐⭐⭐ "Stronger than 0.4mm" - Jason B., USA
"The CCMT060208 is my go-to when I need a bit more edge strength. PS breaker keeps the chips small and the heat away from the part."
⭐⭐⭐⭐⭐ "No smearing on the edge" - Paolo M., Italy
"The cermet material is amazing. No built-up edge even when I run it without coolant. Very clean results."
⭐⭐⭐⭐⭐ "Original Quality" - Lucas P., Brazil
"Authentic Japan stock. Fast shipping to South America. Will continue to buy for our shop."
Technical Q&A
Q: Why choose the 0.8mm radius over 0.4mm?
A: The 0.8mm (08) radius is stronger and can handle higher feed rates, which is great for improving productivity while still getting a high-quality finish.
Q: Does cermet require coolant?
A: Cermet is highly heat-resistant and can be used dry for finishing to avoid thermal shock. However, consistent coolant flow can help with chip evacuation.
Q: Which boring bars are compatible?
A: Any standard **SCLCR06** or **SCLCR1/4** internal or external holder is compatible with this insert.
Expert Machining Tip: Why NS9530?
For precision machining where surface quality is non-negotiable, Cermet (NS9530) is the superior choice over carbide. It prevents the workpiece material from welding to the edge, ensuring a consistent tool life and an elite final finish on every part.
