WNMG080408-TS NS9530 Tungaloy Turning Insert
High-Performance Cermet for Superior Surface Finish in Steel
Product Overview
"Which insert is most effective for achieving a high-gloss surface finish on alloy steel while maintaining dimensional accuracy over long production runs?"
The Tungaloy WNMG080408-TS NS9530 is a specialized Cermet (Ceramic-Metallic) insert designed for high-precision finishing. The NS9530 grade provides exceptional chemical stability and resistance to oxidation, preventing the "built-up edge" (BUE) that causes surface dullness. Featuring the TS (Finishing) chipbreaker, this insert offers a sharp cutting edge and a robust 0.8mm radius, striking a perfect balance between surface brilliance and edge strength.
Key Performance Advantages
- NS9530 Cermet Grade: Engineered for P01-P20 range finishing with high fracture toughness and thermal resistance.
- Mirror Finish Surface: Low affinity to steel workpieces ensures shiny, precise surfaces and eliminates the need for secondary grinding.
- TS Geometry: A sharp rake angle ensures low cutting force, preventing deflection on thin-walled parts.
- Cost Efficiency: 6 usable cutting edges per insert due to the Trigon (W) shape.

Verified Performance Reviews
"The surface finish is unbelievable. We cut our grinding time in half by finishing with NS9530."
— James W., USA"Eccellente su acciaio C45. Finitura a specchio garantita."
— Marco L., Italy"Best cermet insert I've used. Extremely consistent tool life across batches."
— Robert G., Germany"品質は非常に安定しています。仕上げ面がとても綺麗です。"
— Yukihiro T., JapanFrequently 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, use a carbide grade like T9215.
Q: What is the benefit of the 0.8mm radius (08) in finishing?
A: A 0.8mm radius provides higher edge strength and can handle slightly higher feed rates than a 0.4mm radius while still achieving excellent surface finish if the feed/speed is optimized.
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.
