Tungaloy TNGG160404R-P NS9530 Turning Insert
High-Performance Cermet NS9530 | Precision -P Chipbreaker | 0.4mm Right-Hand Radius
How can I get a mirror finish on carbon steel parts without grinding?
The Tungaloy TNGG160404R-P NS9530 is a high-precision right-hand cermet insert specifically engineered for the fine finishing of steel and alloy steels. Utilizing the advanced NS9530 cermet grade, this insert provides exceptional resistance to oxidation and built-up edge (BUE), which is the key to achieving ultra-smooth, high-gloss surface finishes. The 0.4mm corner radius (04) combined with the -P precision chipbreaker ensures excellent chip evacuation at shallow depths of cut. 100% Made in Japan, it is the professional choice for CNC high-speed precision turning.
NS9530 Premium Cermet
A titanium-based cermet grade with high fracture toughness and thermal stability. It maintains edge sharpness much longer than standard carbide when finishing steel.
-P Precision Breaker
Optimized for light loads and precision finishing. The geometry forces chips to break cleanly, preventing the "bird-nesting" that can ruin surface integrity.
Mirror-Surface Output
The low chemical affinity for steel prevents the material from sticking to the tool, resulting in a superior luster often comparable to grinding processes.

Recommended Cutting Parameters (NS9530 Cermet)
-
Cutting Speed (Vc): 100 - 300 m/min (High-speed for gloss)
-
Feed Rate (f): 0.05 - 0.20 mm/rev (Precision zone)
-
Depth of Cut (ap): 0.1 - 1.0 mm (Finishing depth)
*B2B Pro-Tip: Cermet is an ideal choice for dry finishing steel. If using coolant, ensure the flow is high and consistent to prevent thermal shock.*
4. Primary Applications

Reviews from Professional CNC Workshops
⭐⭐⭐⭐⭐ "Surface Gloss is Unbeatable" - Markus E., Germany
"Tungaloy's NS9530 is my standard for steel finishing. The Ra values we achieve on 1045 steel are better than our previous supplier's carbide. 10/10."
⭐⭐⭐⭐⭐ "Stable Performance" - S. Tanaka, Japan
"Consistent quality. The 0.4mm radius is very robust. Using this in automated lathe production with excellent tool life."
⭐⭐⭐⭐ "Great Chip Control" - David L., USA
"The -P breaker works exactly as described. Even at 0.1mm DOC, the chips break properly. No surface scratching."
⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Ahmed R., UAE
"Beyond provided authentic factory-sealed boxes and the technical data was very helpful for our machine setup."
⭐⭐⭐⭐⭐ "Fast Delivery" - Lucas P., Brazil
"Genuine Japan product. High-speed finishing on alloy steel is stable and the finish is beautiful."
8. FAQ - Professional Support
Q: Can I use NS9530 for heavy roughing?
A: No. NS9530 is a cermet grade designed for finishing. For heavy roughing, please use a CVD coated carbide grade like T9215.
Q: Why choose the 0.4mm radius over 0.8mm?
A: The 0.4mm (04) radius produces lower cutting forces and is better for fine profiling and reducing vibration on thin-walled parts.
Tech Tip: Cermet vs Carbide for Steel
While carbide is tougher, **Cermet (NS9530)** maintains sharp edges longer at high speeds because it won't chemically react with steel as easily. Use it for the final touch to get that professional mirror shine. **Tungaloy Japan** - Excellence in surface technology.
