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
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.
