Tungaloy SCMT09T304-PS NS9530 Insert
Mirror Steel Finishing | -PS Precision Breaker | NS9530 Cermet Grade
How to achieve a mirror finish on steel with SCMT cermet inserts?
The Tungaloy SCMT09T304-PS NS9530 is a premium square cermet turning insert designed for high-speed finishing of carbon and alloy steels. Utilizing the advanced NS9530 cermet grade, this insert offers superior chemical stability and resistance to oxidation, resulting in an exceptional surface finish that often eliminates the need for secondary grinding. The -PS chipbreaker is precision-engineered for finishing to light-medium depths of cut, ensuring excellent chip evacuation and low cutting resistance. Made in Japan, this CNC cermet insert is the professional choice for automotive and precision instrument components.
NS9530 Cermet Grade
A premier grade with high wear and fracture resistance. Ideal for finishing steel where surface gloss is critical.
-PS Precision Breaker
Positive rake angle design provides sharp cutting edges, reducing built-up edge and minimizing workpiece vibration.
Thermal Stability
High resistance to heat allows for increased cutting speeds (Vc), improving production efficiency without sacrificing accuracy.

8. FAQ - Professional Support
Q: Is NS9530 cermet better than coated carbide?
A: For finishing steel where gloss and dimensional accuracy are key, cermet is superior due to its chemical stability at high speeds.
Q: Can I use this for interrupted cuts?
A: Cermet is more brittle than carbide. For interrupted cuts, we recommend Tungaloy T9125 or T9225 carbide grades.
Q: Does it fit SSDCN tool holders?
A: Yes, it is a standard ISO SCMT09T3 size and is fully compatible with SSDCN series holders.
Expert Insight: Cermet Finishing Advantage
In high-speed finishing, cermet resists "welding" of the workpiece material to the tool. The NS9530 grade leverages this to provide longer tool life and a much brighter finish compared to traditional carbide. For the ultimate surface, the SCMT09T304-PS is the industrial gold standard.
