Tungaloy DCMT11T302-24 NS9530 Turning Insert
Mirror Finish Specialist | Premium NS9530 Cermet | Made in Japan
How do I get a mirror finish on carbon steel parts?
The Tungaloy DCMT11T302-24 NS9530 is a high-performance cermet turning insert specifically engineered for precision finishing operations. Unlike traditional carbide, the NS9530 cermet grade provides exceptional chemical stability and high resistance to oxidation. This prevents the "built-up edge" (BUE) that often ruins surface Ra on steel workpieces. The -24 chipbreaker is designed for light finishing, featuring a sharp cutting edge and a optimized rake angle for superior chip control at high speeds. This Japan-made indexable turning tool is a favorite for CNC machining shops that require high-gloss finishes and tight dimensional tolerances. By integrating this long-tail keywords optimized insert into your workflow, you can significantly reduce secondary polishing processes and extend your tool life.

What makes NS9530 cermet better than coated carbide?
The NS9530 Grade is a specialized cermet (ceramic-metal composite) that maintains high hardness at elevated temperatures. In precision machining, the low affinity between cermet and steel workpieces ensures that the DCMT11T302-24 creates a superior surface luster compared to coated carbide. The -24 chipbreaker geometry is a masterpiece of finishing design, providing stable chip evacuation even at extremely low depths of cut. For CNC machining of small precision parts, the 0.2mm corner radius allows for intricate detailing while the cermet substrate ensures the edge stays micro-sharp for hundreds of cycles. This indexable turning tool is the ultimate solution for high-productivity steel finishing.
Recommended Cutting Parameters (NS9530)
-
Cutting Speed (Vc): 120 - 320 m/min
-
Feed Rate (f): 0.03 - 0.12 mm/rev
-
Depth of Cut (ap): 0.1 - 1.2 mm
*Pro Tip: Cermet inserts perform best at high speeds. Avoid low-speed machining to prevent micro-chipping of the sharp edge.*
Feedback from Global Machinists

Technical Tooling Q&A
Q: Can I use this for stainless steel?
A: NS9530 is primarily for steel. For stainless, cermet can be used for very light finishing, but a PVD carbide might offer better toughness for sticky materials.
Q: Is coolant required for cermet?
A: Cermet has high heat resistance and can be used dry. However, for a superior finish, light coolant helps with chip evacuation. Avoid heavy thermal shock.
Q: What tool holder fits this DCMT 11T3?
A: This fits standard ISO holders like the SDJCR/L 1212 or 1616 series, and boring bars such as S...-SDUCR/L.
Expert Tip: Why Cermet over Carbide for Ra?
For precision machining, Cermet (NS9530) has a much lower affinity for steel than Tungsten Carbide. This means no material sticks to the edge, resulting in the brilliant "Japan-finish" surface luster that your customers demand.
