Tungaloy TNGG160408R-C NS9530 Turning Insert
Precision Cermet Grade | NS9530 Gloss Finish | 0.8mm Right-Hand Radius
What is the best cermet insert for high-gloss finishing and stable edge strength?
The Tungaloy TNGG160408R-C NS9530 is a high-performance right-hand cermet turning insert engineered for precision finishing in ISO P (Steel) and ISO M (Stainless Steel). Powered by the NS9530 uncoated cermet grade, this tool excels in creating a mirror-like surface finish by resisting chemical wear and built-up edge (BUE). The 0.8mm corner radius (08) provides a sturdier edge than smaller radii, allowing for slightly higher feed rates without sacrificing surface integrity. 100% Made in Japan, it is the industrial benchmark for CNC professionals seeking aesthetic perfection and dimensional stability.
NS9530 Cermet Grade
A non-coated cermet featuring high thermal stability. Its low affinity for steel ensures the workpiece remains bright, significantly reducing the need for secondary polishing.
-C Finishing Chipbreaker
Specifically designed for light finishing passes. The -C geometry ensures excellent chip control at shallow depths, preventing surface scratches and chip bird-nesting.
Right-Hand Precision
Engineered for Right-hand tool holders (WTJNR / MTJNR). The optimized cutting edge orientation provides maximum stability during high-speed external turning.

Finishing Parameters for NS9530 Cermet
-
Cutting Speed (Vc): 100 - 250 m/min (High Speed for Gloss)
-
Feed Rate (f): 0.10 - 0.25 mm/rev (Stable Finishing)
-
Depth of Cut (ap): 0.2 - 1.2 mm
*B2B Pro-Tip: The 0.8mm radius is more durable than 0.4mm, making it ideal for finishing passes where edge strength is needed to maintain dimensional tolerance.*
4. Primary Applications
- High-precision finish turning of alloy and carbon steels.
- Final passes for aesthetic components in automotive parts.
- Precision machining of pins and shafts with high Ra requirements.
- Boring operations in stainless steel where gloss is critical.
5. Tool Compatibility
Standard TN** 1604 interface. Fits WTJNR or MTJNR Right-hand external holders. Compatible with S-WTJNR boring bars for internal finishing.

CNC Specialist Testimonials
⭐⭐⭐⭐⭐ "Surface Gloss is Superb" - David K., USA
"Switched to NS9530 for our finish passes on 4140 steel. The 0.8mm radius holds a mirror finish across long production runs perfectly."
⭐⭐⭐⭐⭐ "Stable Cutting Edge" - Hans L., Germany
"Consistent results. Very reliable cermet grade. No built-up edge even after hours of continuous finishing. Tungaloy Japan quality."
⭐⭐⭐⭐ "Great Chip Flow" - Hiroki S., Japan
"The -C breaker handles light depths of cut without any entanglement issues. Fast shipping from the beyond team."
⭐⭐⭐⭐⭐ "B2B Choice" - Marco V., Italy
"Original packaging and technical advice were spot on. This insert saved us a secondary grinding operation on several parts."
⭐⭐⭐⭐⭐ "Top Quality" - Arjun M., India
"Genuine Tungaloy stock. Significant reduction in cost per piece due to the stability of the NS9530 grade."
8. FAQ - Precision Tooling Support
Q: Why choose the 0.8mm (08) radius over 0.4mm for finishing?
A: The 0.8mm radius offers a stronger edge and better heat dissipation, allowing for higher feed rates while maintaining an excellent surface finish.
Q: Can I use NS9530 for interrupted finishing cuts?
A: Cermet is more brittle than carbide. It is highly recommended for continuous finishing. For heavy interrupted cuts, we suggest using a dedicated coated carbide grade.
Tech Tip: Cermet Finish vs. Carbide
For the highest gloss with **NS9530**, maintain high cutting speeds. Cermet thrives where carbide "smears." **Tungaloy Japan** - Leading in surface excellence and precision finishing.
