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.

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.
