Tungaloy TNGG160408R-P NS9530 Turning Insert
High-Performance Cermet Grade NS9530 | Precision -P Chipbreaker | 0.8mm Right-Hand Radius
What is the best cermet insert for high-gloss finishing on alloy steel?
The Tungaloy TNGG160408R-P NS9530 is a high-precision right-hand cermet insert specifically designed for finishing operations where surface quality and dimensional accuracy are paramount. Utilizing the NS9530 premium cermet grade, this insert offers exceptional resistance to oxidation and built-up edge, resulting in a mirror-like finish on carbon and alloy steels. The 0.8mm corner radius (08) provides enhanced edge strength for stable finishing at higher feed rates. 100% Made in Japan, it is the industrial choice for CNC operators requiring mirror-like finishes and long-term dimensional stability.
NS9530 Cermet Grade
A titanium-based cermet grade with high hardness and excellent thermal stability. It maintains edge sharpness much longer than carbide when finishing steel at high speeds.
-P Precision Breaker
Specifically designed for light loads. It effectively controls chips at shallow depths of cut, preventing surface damage and ensuring a scratch-free workpiece.
0.8mm Stable Radius
The 0.8mm radius offers a perfect balance between finishing quality and edge durability, allowing for increased feed rates without sacrificing surface integrity.

"Fast shipping and genuine Tungaloy inserts. Best source for our workshop's high-precision finishing needs."
8. FAQ - Professional Support
Q: Why use Cermet (NS9530) instead of Carbide?
A: Cermet has a higher resistance to built-up edge and oxidation at high temperatures, which allows it to maintain a sharper edge and produce a superior surface finish on steel.
Q: Can I use this R-P insert in a left-hand holder?
A: No. This is a Right-hand (R) insert. It must be paired with a Right-hand holder (WTJNR) to ensure the chipbreaker faces the workpiece correctly.
Tech Tip: Cermet Handling
Cermet is more brittle than carbide. For best results with **NS9530**, avoid heavy intermittent cuts and ensure high spindle speeds. **Tungaloy Japan** - Excellence in precision surface finishing technology.
