Tungaloy VBMT110302-PS NS9530 Insert

High-Gloss Cermet Finishing | 0.2mm Precision Radius | NS9530 Grade

Which cermet insert provides the best surface finish on steel?

The Tungaloy VBMT110302-PS NS9530 is an elite cermet turning insert specifically engineered for the "super-finishing" phase of CNC machining. Unlike traditional carbide, the NS9530 cermet grade offers superior resistance to oxidation and built-up edge, resulting in a mirror-like surface finish on carbon and alloy steels. With its sharp 0.2mm corner radius and -PS (Positive Sharp) geometry, this 35-degree rhombic insert is the industrial standard for precision profiling where dimensional accuracy and aesthetic quality are non-negotiable. 100% Made in Japan.

NS9530 Cermet Grade

A titanium-based cermet that maintains edge sharpness longer than carbide at high speeds, delivering incredible gloss and preventing chemical wear.

0.2mm Super-Fine Radius

The ultra-small RE0.2 minimizes cutting forces and radial pressure, effectively eliminating vibration on slender parts and thin-wall tubes.

-PS Sharp Geometry

A dedicated finishing chipbreaker that controls micro-chips at very low depths of cut, ensuring a clean profile without surface marring.

Super-Finishing Recommended Parameters

  • Cutting Speed (Vc): 120 - 300 m/min (Highly recommended for high-speed use)
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.1 - 0.8 mm

4. Primary Applications

  • High-gloss mirror finishing of alloy steel and carbon steel.
  • Final profiling passes where Ra roughness must be under 0.8µm.
  • Swiss-type CNC machining for medical and watch components.
  • Precision turning where tool pressure must be kept minimal.

5. Equipment Compatibility

Fits all standard ISO VBMT 1103 pockets. Works best with SVJCR/L external profiling holders and SVUCR/L boring bars. Compatible with Citizen, Star, Tsugami, Mazak, and Haas lathes.

Global Customer Feedback

⭐⭐⭐⭐⭐ "The Surface Gloss is Unreal" - F. Miller, Germany
"Switched from AH725 to NS9530 for our final pass on 1045 steel shafts. The parts look like they've been polished. Incredible cermet grade."

⭐⭐⭐⭐⭐ "Perfect for Precision Work" - H. Sato, Japan
"The 0.2mm radius is essential for our medical components. Very stable at high RPM."

⭐⭐⭐⭐⭐ "Great Chip Control" - Carlos M., Spain
"Usually, finishing breakers struggle at 0.05mm DOC, but the -PS keeps the chips under control. No bird-nesting."

⭐⭐⭐⭐⭐ "Fast Shipping" - D. Thompson, Australia
"Beyond Li provided genuine Tungaloy inserts with full documentation. Arrived in Melbourne in 4 days."

8. FAQ - Support for Machinists

Q: Can I use NS9530 for interrupted cuts?

A: Cermet is more brittle than carbide. We recommend NS9530 for continuous finishing only. Use AH725 for light interrupted cuts.

Q: Does this insert require coolant?

A: Cermet can be used dry or with high-pressure coolant. For mirror finishes, high-speed dry machining often yields excellent results.

Q: Why choose 0.2mm over 0.4mm?

A: 0.2mm is superior for tight corners and reducing radial pressure in slender parts, though it requires slightly more care with feed rates.

Tech Tip: Cermet Performance Optimization

To achieve the **ultimate mirror finish** with **NS9530**, use a high cutting speed (above 200 m/min) and a light feed. The heat generated at high speeds softens the chip, allowing the **cermet edge** to glide through the material. **Tungaloy Japan** - Excellence in Finishing.

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.
