Tungaloy TNGG160402R-C NS9530 Turning Insert
Precision Cermet Grade | NS9530 Mirror Finish | 0.2mm Right-Hand Radius
What is the best cermet insert for high-gloss finishing on steel?
The Tungaloy TNGG160402R-C NS9530 is a specialized cermet turning insert engineered for ultra-high precision finishing in ISO P (Steel) and ISO M (Stainless Steel) machining. Utilizing the NS9530 uncoated cermet grade, this insert offers superior resistance to oxidation and chemical wear, resulting in a stable edge that produces a mirror-like surface finish. The Right-hand (R) orientation and 0.2mm corner radius (02) are perfect for intricate profiling and light finishing passes. 100% Made in Japan, it is designed for CNC operators who demand the highest surface integrity and dimensional stability.
NS9530 Cermet Grade
A non-coated cermet with low affinity to steel, effectively preventing built-up edge (BUE). It maintains exceptional hardness at high cutting temperatures for long-lasting precision.
-C Precision Chipbreaker
The -C geometry is optimized for finishing, providing excellent chip control at very low feed rates to ensure a clean, scratch-free surface on the workpiece.
0.2mm Sharp Radius
The small 0.2mm radius minimizes cutting forces, making it ideal for thin-walled parts and delicate finishing where vibration control is critical.

"The -C breaker works exactly as described. No stringy chips even at very light depths of cut. Tungaloy Japan quality."
⭐⭐⭐⭐ "Very Stable" - Tan M., Singapore
"Consistent results across the entire batch. Beyond OYYU provided the original stock fast. Highly recommended partner."
⭐⭐⭐⭐⭐ "Great for Small Parts" - Marco P., Italy
"The 0.2mm radius is perfect for my precision profiling work. Low cutting pressure means no part deflection."
⭐⭐⭐⭐⭐ "Authentic Product" - Rahul S., India
"Genuine Tungaloy inserts in factory-sealed boxes. Excellent B2B service and technical advice from the team."
8. FAQ - Professional Support
Q: Why use cermet instead of coated carbide for finishing?
A: Cermet has a lower chemical affinity for steel, which prevents built-up edge (BUE) and results in a significantly higher surface gloss compared to carbide.
Q: What does the 'R' in TNGG160402R-C stand for?
A: It stands for Right-hand. This refers to the tool orientation. You must use a Right-hand holder (like WTJNR) to correctly utilize the chipbreaker geometry.
Tech Tip: Cermet Finishing Excellence
For the best results with **NS9530**, maintain high cutting speeds to keep the edge clean. This grade is specifically built for continuous finishing. **Tungaloy Japan** - Leading in surface integrity and precision engineering.
