WNMG080404-TS NS9530 Tungaloy Turning Insert
High-Speed Cermet Solution for Mirror-Like Surface Finishing
Product Overview
"Which insert grade is best for achieving a high-gloss surface finish on steel parts while maintaining dimensional stability at high cutting speeds?"
The Tungaloy WNMG080404-TS NS9530 is a premium Cermet insert specifically designed for finishing operations in steel. The NS9530 grade offers exceptional resistance to oxidation and built-up edge (BUE), which is critical for achieving a "mirror finish." Paired with the TS (Finishing) chipbreaker, this insert provides a sharp cutting edge and precise chip control at light depths of cut, ensuring high productivity and superior surface integrity.
Core Performance Advantages
- NS9530 Cermet Grade: High fracture toughness and wear resistance optimized for P05-P20 range steel finishing.
- Mirror Finish Capability: Low chemical affinity with steel prevents welding and ensures a smooth, shiny surface.
- TS Chipbreaker Geometry: Designed for high precision with small depths of cut, providing excellent chip breaking at high speeds.
- Economic 6-Edge Design: The Trigon (W) shape provides more cutting edges than standard diamond inserts, lowering cost-per-part.

Global Customer Testimonials
"NS9530 is simply the best for high-gloss steel parts. We stopped grinding after switching to these cermets."
— Mark J., USA"Eccellente finitura superficiale. Il rompitruciolo TS è perfetto per passate leggere."
— Pietro V., Italy"Quality is consistent. Tool life at 300 m/min is very impressive."
— Hiroshi K., Japan"Top Standzeit bei der Schlichtbearbeitung. Sehr empfehlenswert."
— Klaus M., GermanyFrequently Asked Questions
Q: Can I use NS9530 for interrupted cuts?
A: Cermet is more brittle than carbide. While NS9530 has high toughness for its class, it is best suited for continuous finishing. For heavy interruptions, consider AH725.
Q: Does this insert require coolant?
A: Cermet performs exceptionally well in dry cutting because it resists thermal shock better than carbide. However, if using coolant, ensure it is consistent and high-pressure.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
