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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
