Tungaloy SCMT09T302-24 NS9530 Insert
Precision Steel Finishing | 24 Chipbreaker | Premium NS9530 Cermet Grade
What is the best cermet insert for precision steel finishing?
The Tungaloy SCMT09T302-24 NS9530 is a high-precision square cermet turning insert specifically developed for high-speed finishing of carbon and alloy steels. Utilizing the advanced NS9530 cermet grade, this tool offers exceptional wear resistance and chemical stability, which results in a superior surface finish that often eliminates the need for grinding. The 24 chipbreaker is specialized for light-duty finishing, providing perfect chip control even at low depths of cut. Made in Japan, this CNC turning insert is a staple in high-volume automotive and precision engineering production lines.
NS9530 High-Tech Cermet
Features high resistance to oxidation and metal adhesion, ensuring the cutting edge stays sharp for a mirror-like finish.
24 Finishing Chipbreaker
Designed for light finishing passes, offering a sharp cutting action and stable chip evacuation at high speeds.
Dimensional Stability
Cermet's thermal properties ensure minimal tool expansion, leading to tighter tolerances across long production runs.

⭐⭐⭐⭐⭐ "Mirror Finish on Alloy Steel" - Markus K., Germany
"I was struggling to get a good finish on 4140 steel. These SCMT cermet inserts made it look like it was ground. Highly recommended."
⭐⭐⭐⭐⭐ "Incredible Precision" - T. Yamamoto, Japan
"The 0.2mm radius is perfect for sharp corners. Dimensional stability is excellent over long batches."
⭐⭐⭐⭐ "Very Sharp" - B. Watson, USA
"Sharp edge and great chip breaker. We use these on our Swiss lathes for final passes on automotive pins."
⭐⭐⭐⭐⭐ "Reliable B2B Partner" - G. Rossi, Italy
"Fast delivery from CNCHome-Beyond. These are original Tungaloy parts and perform beautifully."
⭐⭐⭐⭐⭐ "Top Quality" - A. Lim, Singapore
"Cermet is much better than carbide for finishing steel. Less heat buildup and a much cleaner cut."
8. FAQ - Support Center
Q: Can I use this for stainless steel finishing?
A: While it can work on some 300 series stainless, NS9530 is primarily optimized for carbon and alloy steels (ISO P materials).
Q: What is the benefit of cermet over carbide?
A: Cermet is more chemically stable at high temperatures, which prevents the material from welding to the edge, resulting in a superior surface finish.
Q: Does it fit standard SCMT holders?
A: Yes, it is a standard ISO SCMT09T3 size and fits any matching tool holder like the SSDCN series.
Expert Tip: Cermet Speed vs. Carbide
In high-precision finishing, cermet is king. The NS9530 grade allows you to run at higher surface speeds than traditional carbide while maintaining a sharp edge. This reduces cycle times and significantly improves the Ra value of your finished parts, providing that professional industrial finish.
