Tungaloy TNGG160404L-P NS9530 Turning Insert
Premium Cermet Grade NS9530 | Precision -P Chipbreaker | 0.4mm Left-Hand Radius
What is the best cermet insert for high-speed steel finishing?
The Tungaloy TNGG160404L-P NS9530 is a high-precision left-hand cermet turning insert engineered specifically for the fine finishing of carbon and alloy steels. Utilizing the advanced NS9530 cermet grade, this tool offers exceptional oxidation resistance and thermal stability, allowing for high cutting speeds while maintaining a mirror-like surface finish. The 0.4mm corner radius (04) combined with the -P precision chipbreaker provides superior chip control and dimensional accuracy. 100% Made in Japan, it is the industrial standard for CNC operators seeking peak performance in steel finishing.
NS9530 Cermet Grade
A titanium-based cermet grade with high fracture toughness. It prevents built-up edge (BUE), ensuring the cutting edge remains sharp for extended periods during high-speed finishing.
-P Precision Geometry
Designed for light loads and precision cuts. The -P breaker keeps cutting forces low, which is critical for preventing vibration and achieving tight tolerances on thin-walled parts.
G-Class Tolerance
The ground periphery ensures high repeatability. CNC offsets remain stable during insert changes, maximizing machine uptime in automated production.

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: Does this work in a Right-hand tool holder?
A: No. This is a Left-hand (L) insert. It must be paired with a Left-hand (L) tool holder (WTJNL) to ensure the chipbreaker faces the workpiece correctly.
Tech Tip: Cermet Handling
Cermet is more brittle than carbide. To maximize tool life with **NS9530**, avoid heavy intermittent cuts and ensure high spindle speeds. **Tungaloy Japan** - Precision in every cut.
