Tungaloy SCMT120404-24 NS9530 Insert
Mirror Steel Finishing | 24 Precision Breaker | NS9530 Cermet Grade
How to achieve a mirror finish on steel using cermet inserts?
The Tungaloy SCMT120404-24 NS9530 is a high-performance square cermet turning insert designed for high-speed finishing of carbon and alloy steels. Featuring the advanced NS9530 cermet grade, this insert provides superior chemical stability and resistance to oxidation, allowing for incredibly smooth surface finishes that often eliminate the need for secondary grinding. The 24 chipbreaker is precision-engineered for light finishing depths, ensuring excellent chip evacuation even at high cutting speeds. Made in Japan, this CNC turning insert is the industry standard for high-precision components in the automotive and aerospace sectors.
Advanced NS9530 Grade
A premier cermet grade that prevents material adhesion (BUE), maintaining a sharp edge for extended periods during high-speed finishing.
24 Chipbreaker Design
Specifically tuned for light-duty finishing passes, offering low cutting resistance and superior dimensional accuracy.
High Thermal Stability
Cermet's ceramic-metal hybrid structure ensures the tool maintains its hardness at high surface speeds where carbide would fail.

8. FAQ - Finishing Solutions
Q: Can I use this for roughing steel?
A: No. Cermet is designed for high-speed finishing. For heavy roughing, please use Tungaloy AH series carbide grades.
Q: Does cermet require special tool holders?
A: No, it fits standard ISO holders like the SSDCN series for SCMT 1204 inserts.
Q: Is NS9530 better than coated carbide?
A: For high-speed finishing where a superior surface finish is required, NS9530 cermet is significantly better due to its chemical stability.
Expert Insight: The Cermet Advantage
In high-precision finishing, cermet is superior because it resists "welding" of the workpiece material to the tool. The NS9530 grade allows for much higher cutting speeds while maintaining edge sharpness, ensuring your SCMT120404 inserts deliver a world-class mirror finish consistently.
