Tungaloy VCMT110304-PS NS9530 Precision Insert
Ultimate Surface Finish for Steel | NS9530 Premium Cermet Grade
Which insert provides the best mirror finish on CNC steel parts?
The Tungaloy VCMT110304-PS NS9530 is the industrial gold standard for high-speed finishing of carbon and alloy steels. Utilizing the advanced NS9530 cermet grade, this insert offers exceptional chemical stability and resistance to built-up edge (BUE). The -PS (Positive Sharp) chipbreaker geometry is specifically engineered for light depths of cut, ensuring stable chip evacuation and a high-gloss surface finish that often eliminates the need for secondary grinding operations.

NS9530 Cermet Tech
High-grade titanium-based cermet ensures long tool life and incredible surface gloss by preventing oxidation at high temperatures.
-PS Sharp Geometry
The high-rake sharp cutting edge reduces cutting resistance and prevents workpiece deflection on slender shafts.
PVD Coating Stability
Advanced PVD layering provides a smooth surface that minimizes friction and enhances wear resistance in continuous finishing.

Technical FAQ
Q: What is the main benefit of NS9530 cermet?
A: Cermet has a low chemical affinity for steel, which prevents chip welding and ensures a high-gloss surface finish and dimensional stability.
Q: Can I use this for stainless steel?
A: While cermet can cut stainless steel, it is primarily optimized for carbon and alloy steels. For stainless steel, we recommend PVD coated carbide grades like AH725.
Q: Is coolant necessary?
A: Cermet performs exceptionally well in dry machining, which prevents thermal cracking. If using coolant, ensure it is high-pressure and consistent.
Expert Machinist Tip
When using the **-PS chipbreaker**, ensure your depth of cut stays within the recommended 0.2mm to 1.0mm range. If you go too deep, the sharp edge may chip; if too shallow, you may face bird-nesting chips. For a mirror finish, increase the cutting speed slightly while maintaining a low feed rate. **Tungaloy Engineering - Precision Beyond Limits.**
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.
