Tungaloy VNMG160404-TS NS9530 Cermet Insert

Mirror-Finish Precision | High-Speed Steel Finishing Grade

"Which insert is best for achieving a high-gloss finish and dimensional accuracy in steel turning?"

The Tungaloy VNMG160404-TS NS9530 is a premium Cermet (Ceramic-Metallic) insert specifically designed for fine finishing operations. Unlike traditional carbide, the NS9530 grade provides exceptional chemical stability and resistance to built-up edge, which is the secret to achieving mirror-like surface finishes. The -TS (Finishing) chipbreaker features a sharp, positive cutting edge and a specialized geometry that ensures stable chip control at very light depths of cut and high speeds. This 35° rhombic profile is ideal for intricate detailing and external/internal profiling where surface integrity is paramount.

NS9530 Cermet Grade

Uncoated cermet grade with superior fracture resistance and thermal stability. Maintains a sharp edge longer than carbide during finishing.

-TS Finishing Geometry

High-precision chipbreaker designed for finishing. It minimizes cutting forces and prevents vibration, resulting in superior Ra values.

Chemical Wear Resistance

Low affinity for workpiece materials (Steel) prevents built-up edge, ensuring consistent dimensional accuracy across long production runs.

Industrial User Reports

⭐⭐⭐⭐⭐ "Like a Mirror" - David R., USA
"Switched from carbide to NS9530 for our final pass. The surface finish is incredible—Ra 0.4 easily achievable on steel shafts."

⭐⭐⭐⭐⭐ "Stable and Accurate" - Giovanni B., Italy
"The -TS chipbreaker handles thin chips perfectly. Dimensional accuracy is very stable over 200 parts. Highly recommended."

⭐⭐⭐⭐ "Great for Finishing" - Sato K., Japan
"Very low wear during continuous finishing. Tungaloy quality is always top-tier. Fast shipping from Beyond CNC."

⭐⭐⭐⭐⭐ "No Built-up Edge" - Markus W., Germany
"NS9530 is superior for clean cuts. No welding of material on the tip even at high speeds."

Technical FAQ

Q: Can I use Cermet for interrupted cutting?

A: Cermet is more brittle than carbide. It is primarily recommended for continuous finishing. For heavy interruptions, a tough carbide grade like T9125 is better.

Q: Is coolant required for NS9530?

A: Cermet can be used for both dry and wet cutting. However, consistent cooling is better to prevent thermal shock if you choose to use it.

Industrial Tip: Surface Integrity

To maximize the benefit of **Cermet NS9530**, increase your cutting speed (Vc) compared to carbide. Higher speeds improve the surface finish and prevent material welding. **BEYOND CNC** - Your Precision Partner.

Technical FAQ & Buying Guide

How do I choose the correct specification?

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.

How can I check compatibility with my existing setup?

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.

What quantity and price unit am I 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.

How should I choose cutting parameters?

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.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
