WNMG080408-37 NS9530 Tungaloy Turning Insert
High-Speed Precision Cermet for Superior Surface Integrity
Product Overview
"Which insert is best for achieving a mirror-like surface finish on steel at high speeds while maintaining tight tolerances?"
The Tungaloy WNMG080408-37 NS9530 is a premium Cermet insert designed specifically for finishing operations. Unlike traditional carbide, the NS9530 grade offers exceptional resistance to oxidation and built-up edge (BUE), which is crucial for high-gloss finishes. The -37 Chipbreaker provides a stable cutting edge with a positive rake angle, optimized for light-to-medium cutting depths, ensuring excellent chip control even in ductile steels.
Core Advantages
- NS9530 Cermet Grade: High fracture toughness and wear resistance optimized for P05-P20 range steel.
- Mirror Surface Finish: Cermet's low affinity for steel prevents workpiece welding, resulting in superior gloss.
- -37 Chipbreaker: Engineered for light-load machining, preventing chip bird-nesting in finishing.
- High Dimensional Accuracy: Minimal tool wear maintains tight tolerances throughout long production runs.

Trusted by Global Machinists
"NS9530 grade is a lifesaver for our bearing housings. The surface finish is incredible."
— James L., USA"Eccellente finitura su C45. Chipbreaker -37 perfetto per passate leggere."
— Marco B., Italy"Sehr gute Standzeit bei hohen Schnittgeschwindigkeiten. Original Tungaloy Qualität."
— Klaus M., Germany"Consistent tolerances. Highly recommended for CNC production lines."
— Takashi S., JapanFrequently Asked Questions
Q: Why use Cermet (NS9530) instead of Carbide?
A: Cermet has lower chemical affinity for steel, meaning it resists workpiece welding. This results in much smoother, brighter surface finishes compared to carbide.
Q: Is the -37 chipbreaker suitable for roughing?
A: No. The -37 geometry is specifically optimized for light-to-medium finishing. For roughing, we recommend the TM or TH chipbreakers.
Pro Machining Tip: When using NS9530 Cermet, avoid heavy interrupted cuts. To achieve the best finish, ensure you are running at high cutting speeds (Vc) with consistent coolant flow.
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.
