Tungaloy SNMG120404-TS NS9530 Turning Insert
High-Precision Steel Finishing | Premium NS9530 Cermet Grade | Mirror Surface Finish
How do I achieve a mirror finish on steel parts using CNC turning?
The Tungaloy SNMG120404-TS NS9530 is a specialized cermet turning insert engineered for high-speed finishing of ISO P (Steel). Unlike standard carbide, the NS9530 Cermet grade provides exceptional resistance to built-up edge (BUE) and oxidation, ensuring long-lasting dimensional accuracy and a brilliant surface luster. The -TS chipbreaker is specifically optimized for small depths of cut and low feed rates, delivering precise chip control in light finishing operations. 100% Made in Japan, it is the professional's choice for parts that require high aesthetic quality and tight tolerances.
NS9530 Cermet Technology
A titanium-based ceramic-metal composite that maintains edge sharpness longer than carbide. It offers superior wear resistance at high speeds, ideal for finishing carbon and alloy steels.
-TS Finishing Chipbreaker
The "TS" geometry is designed for high-precision finishing. It manages light chips efficiently, preventing surface scratching and ensuring high process security at low depths of cut.
Exceptional Edge Sharpness
With a 0.4mm corner radius and precise honing, this insert minimizes cutting forces, making it perfect for thin-walled parts and delicate finishing passes.

Machinist Feedback from the Shop Floor
⭐⭐⭐⭐⭐ "Surface finish is like a mirror" - D. Roberts, UK
"Switched from coated carbide to this NS9530 cermet for our finishing pass on steel pins. The results are amazing. No more polishing required!"
⭐⭐⭐⭐⭐ "Top tier Japanese Quality" - K. Schmidt, Germany
"Original Tungaloy cermet is simply better. Dimensional stability is perfect throughout a 500-piece run. Highly recommended."
⭐⭐⭐⭐ "Great for tight tolerances" - T. Sato, Japan
"The TS breaker works very well with small ap. Very predictable wear pattern. Excellent for finishing small diameter shafts."
⭐⭐⭐⭐⭐ "No Built-up Edge!" - S. Patterson, USA
"We were fighting BUE on our low-carbon steel parts. This cermet grade fixed it immediately. Cleaner cut and much faster speeds."
⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Chen W., Singapore
"Prompt delivery and genuine product. These inserts are essential for our precision automotive contracts."
8. FAQ - Precision Finishing Support
Q: Can I use this for roughing?
A: No. Cermet is brittle compared to carbide. It is designed specifically for finishing (light cuts and high speeds). Use a T9125 grade for roughing.
Q: Is NS9530 better than NS9520?
A: NS9530 is a more balanced grade with higher fracture toughness, making it safer for general steel finishing, whereas NS9520 is harder for even higher speed continuous cutting.
Q: Should I use coolant with cermet?
A: While it can be used dry, light oil or high-quality coolant is recommended for finishing to further enhance surface brightness and chip evacuation.
Expert Machinist Tip: Cermet vs. 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 insert, preventing the jagged edges that cause dull finishes. For the best result, keep your cutting speed high and your feed low. Trust **Tungaloy Japan** for world-class CNC precision.
