Tungaloy WNMG080404-37 NS9530 Turning Insert
High-Speed Precision Cermet for Mirror-Like Steel Finishing
Product Overview
"Which insert is best for achieving a high-quality surface finish in steel at high cutting speeds without the cost of coating?"
The Tungaloy WNMG080404-37 NS9530 is the definitive choice for finishing operations. Featuring the NS9530 Cermet grade, this insert offers exceptional resistance to oxidation and built-up edge (BUE), ensuring consistent dimensional accuracy. The -37 Chipbreaker is specifically engineered for light-to-medium cutting, providing excellent chip control at shallow depths of cut, which is critical for preventing workpiece scratching.
Core Performance Advantages
- NS9530 Cermet Grade: High fracture toughness and wear resistance optimized for P05-P20 steel turning.
- Exceptional Surface Finish: Cermet’s low affinity for steel prevents workpiece welding, resulting in a mirror-like finish.
- -37 Geometry: A stable chipbreaker design that prevents chip bird-nesting in light-duty finishing.
- Dimensional Stability: Low thermal expansion ensures precision during long production runs.

Italy: "Superior tool life compared to standard carbide in light cuts."
Frequently Asked Questions
Q: Why use Cermet over Carbide for finishing?
A: Cermet (Ceramic + Metal) has lower chemical affinity for steel, which prevents built-up edge and produces a significantly smoother surface finish.
Q: Can I use this for interrupted cuts?
A: Cermet is more brittle than carbide. For light interruptions, it is fine, but for heavy interruptions, we recommend T9200 series carbide.
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.
