Tungaloy SNMG120408-TS NS9530 Turning Insert
Precision Finishing | NS9530 Cermet Grade | High-Quality Mirror Surface
How can I get a better surface finish on steel without extra polishing?
The Tungaloy SNMG120408-TS NS9530 is a world-class cermet turning insert specifically optimized for finishing operations in ISO P (Steel). By utilizing the NS9530 Cermet grade, which combines ceramic and metallic properties, this insert provides superior resistance to Built-Up Edge (BUE) and oxidation at high cutting temperatures. The -TS chipbreaker is Tungaloy's answer to precision finishing, providing excellent chip control at light depths of cut and low feed rates. 100% Made in Japan, it ensures your CNC parts achieve a "mirror" luster directly from the lathe.
NS9530 Cermet Grade
Provides extreme hardness and chemical stability. It is less likely to "weld" to the steel workpiece, resulting in a significantly brighter and cleaner surface finish than coated carbide.
-TS Finishing Breaker
Designed for high-precision finishing. It handles fine, thin chips with ease, preventing them from wrapping around the tool or scratching the finished part.
Sharp Edge Strength
The 0.8mm radius (08) offers a perfect balance between edge strength and finish quality, allowing for slightly higher feed rates than an 0.4mm radius while maintaining precision.

Recommended Cutting Parameters (NS9530)
-
Cutting Speed (Vc): 150 - 350 m/min
-
Feed Rate (f): 0.05 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 2.0 mm
*Pro Tip: Cermet works best at high speeds. Avoid low-speed turning to prevent edge build-up.*

⭐⭐⭐⭐⭐ "Mirror Surface Success" - David L., USA
"We replaced our standard carbide with the NS9530 cermet for the final pass on 4140 steel. The finish is absolute mirror quality. No more BUE!"
⭐⭐⭐⭐⭐ "Top Quality Japanese Inserts" - K. Müller, Germany
"Tungaloy cermet is very consistent. This SNMG120408-TS is perfect for our precision shafts. Size control is outstanding throughout the batch."
⭐⭐⭐⭐ "Great Chip Breaking" - S. Tanaka, Japan
"The TS breaker is excellent for light cuts. Even at 0.1mm ap, it breaks the chips perfectly. Very sharp and reliable."
⭐⭐⭐⭐⭐ "Reliable B2B Supplier" - Lee J., Singapore
"Ordered in bulk from CNCHome-Beyond. Delivery was fast to Singapore. The Tungaloy NS9530 is a staple in our shop for steel finishing."
⭐⭐⭐⭐⭐ "Long Tool Life" - G. Russo, Italy
"Surprisingly tough for a cermet. It handles high-speed finishing for a long time before needing a fresh corner. Excellent value."
8. FAQ - Finishing Tips
Q: Can I use this for roughing?
A: No. Cermet is brittle compared to carbide. It is strictly for finishing (light cuts). Use T9125 or similar for roughing operations.
Q: Does this fit standard SNMG 432 holders?
A: Yes. SNMG 120408 is the metric designation for SNMG 432. It is 100% interchangeable in 1/2" IC holders.
Q: Should I use coolant with NS9530?
A: Yes, use high-pressure coolant to further improve surface finish and evacuate fine finishing chips efficiently.
Expert Tip: Cermet vs. Coated Carbide
The **NS9530 Cermet** grade provides a much lower chemical affinity for steel compared to Tungsten Carbide. This means the workpiece material doesn't "stick" to the edge, which is the primary cause of dull finishes. For the best "shine," keep your RPMs high and your feed low. Trust **Tungaloy Japan** for professional CNC results.
