Tungaloy TNGG160404L-C NS9530 Turning Insert
High-Precision Cermet Grade | NS9530 Mirror Finish | 0.4mm Left-Hand Radius
What is the most effective cermet grade for stable finishing in steel?
The Tungaloy TNGG160404L-C NS9530 is a specialized cermet turning insert engineered for high-precision finishing operations in ISO P (Steel) and ISO M (Stainless Steel) machining. Utilizing the NS9530 uncoated cermet grade, this insert provides exceptional resistance to built-up edge (BUE) and oxidation, ensuring a stable cutting edge and a mirror-like surface finish. The Left-hand (L) orientation and 0.4mm corner radius (04) are perfectly balanced for precision profiling and finishing. 100% Made in Japan, it is the professional solution for CNC operations where surface integrity and dimensional accuracy are the highest priorities.
NS9530 Cermet Grade
A non-coated cermet grade that offers superior thermal stability and chemical resistance. It maintains a sharp cutting edge longer than carbide during high-speed finishing passes.
-C Precision Chipbreaker
Specifically designed for finishing, the -C breaker provides excellent chip control at low feed rates, preventing workpiece damage from stringy chips.
Mirror Surface Finish
Cermet's low affinity for steel prevents welding at the cutting edge, resulting in superior Ra values and a bright, aesthetic finish without secondary polishing.

Reviews from CNC Precision Specialists
⭐⭐⭐⭐⭐ "Surface Gloss is Amazing" - Mark R., USA
"We use NS9530 for our finish passes on alloy steel shafts. The mirror finish we get directly from the lathe has cut our production time by 20%."
⭐⭐⭐⭐⭐ "Stable and Reliable" - Dieter W., Germany
"Consistent results throughout the entire batch. Dimensional stability is excellent. Original Japan quality as expected."
⭐⭐⭐⭐ "Great Chip Control" - Tan L., Malaysia
"The -C breaker works very well at light depths of cut. Beyond OYYU team provided excellent technical parameters for our setup."
⭐⭐⭐⭐⭐ "Perfect for Precision" - Marco F., Italy
"The 0.4mm radius gives enough strength for finishing while maintaining low cutting pressure. Highly recommended for precise components."
⭐⭐⭐⭐⭐ "Authentic B2B Partner" - Arjun V., India
"Received in original Tungaloy boxes. Fast delivery and professional support. A reliable partner for our CNC shop."
8. FAQ - Professional Support
Q: Why choose cermet over coated carbide for finishing?
A: Cermet has a much lower chemical affinity for steel, which prevents built-up edge (BUE) and results in a significantly higher surface gloss and longer dimensional stability.
Q: What holder orientation do I need for TNGG160404L-C?
A: This is a Left-hand (L) insert. You must pair it with a Left-hand holder (such as WTJNL or MTJNL) to ensure the chipbreaker performs correctly.
Tech Tip: Optimizing Cermet Tool Life
For the best results with **NS9530**, prioritize high cutting speeds and stable machining environments. Cermet is built for finishing; avoid heavy interrupted cuts to maintain the sharp precision edge. **Tungaloy Japan** - Excellence in surface integrity.
