Tungaloy SNMG120404 NS9530 Cermet Insert
Mirror Finish Excellence | NS9530 High-Speed Grade | Precision Made in Japan
How do I get a high-gloss finish on CNC steel turning?
The Tungaloy SNMG120404 NS9530 is a premier double-sided square turning insert specifically designed for high-precision finishing of ISO P (Steel) materials. Featuring the advanced NS9530 Cermet grade, this insert provides superior chemical stability and thermal resistance compared to traditional carbide. The low affinity for steel prevents workpiece welding, ensuring a mirror-like surface and high dimensional accuracy. As a genuine Made in Japan product, it is the industrial benchmark for machinists who require long tool life during high-speed finishing cycles.
NS9530 Cermet Grade
A premium ceramic-metal composite that maintains edge sharpness at high temperatures, offering incredible wear resistance for finishing carbon and alloy steels.
Standard Chipbreaker
The geometry is optimized for stable chip control at small depths of cut, preventing long, stringy chips from scratching your finished surface.
High Productivity
Achieve higher cutting speeds (Vc) than carbide, reducing cycle times and increasing overall workshop throughput with consistent performance.

Recommended Cutting Parameters (NS9530)
-
Cutting Speed (Vc): 150 - 450 m/min (Ideally dry for maximum brightness)
-
Feed Rate (f): 0.05 - 0.20 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro Tip: For a high-gloss surface, maintain high Vc. Cermets perform best under high heat/high speed conditions.*
4. Product Applications
- Final finishing of automotive shafts and gears.
- High-precision machining of small steel components.
- Achieving superior surface roughness on carbon and alloy steel.
- General job shop work requiring aesthetic surface quality.
5. Holder Compatibility
Universal fit for standard ISO Turning Holders (External: DSBNR/L, PSSNR/L; Internal: S...-PSSNR/L). Compatible with SNMG 1204 pockets on all CNC Lathes.

Professional Machinist Feedback
⭐⭐⭐⭐⭐ "Mirror Surface" - James W., USA
"NS9530 is my secret weapon for steel finishing. The parts come out looking like they were polished. Highly recommend Tungaloy cermets."
⭐⭐⭐⭐⭐ "Longer Life" - G. Wagner, Germany
"I was using carbide but these last 2x longer on finish cuts. Fast shipping and original packaging from the seller."
⭐⭐⭐⭐ "Very Sharp" - T. Nakamura, Japan
"Consistent accuracy for thousands of pieces. Tungaloy Japan quality is never in doubt for cermet tools."
⭐⭐⭐⭐⭐ "Excellent B2B" - F. Silva, Brazil
"We buy these for our automotive factory. Great stock levels and reliable technical data provided."
⭐⭐⭐⭐⭐ "Great Chip Control" - L. Tan, Singapore
"Even at a 0.5mm DOC, the chips break beautifully. No bird-nesting on our CNC lathes with these SNMGs."
8. FAQ - Turning Center Support
Q: Is NS9530 better than carbide for steel?
A: For high-speed finishing where surface quality is key, yes. Cermet has lower chemical affinity for steel, resulting in a cleaner finish.
Q: Can I use coolant with cermet?
A: Cermets thrive in heat. Dry machining is often preferred to prevent thermal shock, but if you must use coolant, ensure it is high-volume and consistent.
Q: Does this fit SNMG 431 holders?
A: Yes, SNMG 120404 is the metric equivalent to the Imperial SNMG 431 specification.
Expert Machinist Insight: The Secret of NS9530
While standard carbide grades are tough, the NS9530 Cermet is built for the "Golden Cut." Because it contains ceramic particles, it won't weld to steel chips even at high cutting speeds. This means you can run your CNC lathe at 300+ m/min and still get a surface that looks polished. If your job demands high-end aesthetics and precise sizing, SNMG120404 NS9530 is the professional’s choice. Trust Japanese excellence.
