Tungaloy VBMT110304-PS NS9530 Insert

High-Gloss Cermet Profiling | 0.4mm Radius | Super-Finishing Specialist

How can I achieve a mirror finish on carbon steel parts?

The Tungaloy VBMT110304-PS NS9530 is the industrial gold standard for achieving high-gloss surface finishes in CNC turning. Utilizing an advanced NS9530 Cermet grade, this insert provides exceptional resistance to built-up edge (BUE) and oxidation, ensuring that your workpiece retains a bright, polished appearance. The 35-degree rhombic geometry is specifically designed for complex profiling, while the -PS (Positive Sharp) chipbreaker enables smooth cutting even at low depths of cut. Whether you are working on automotive components or precision medical devices, this cermet insert delivers unmatched aesthetic and dimensional quality.

Mirror-Surface Technology

The titanium-based cermet substrate offers superior chemical stability, preventing the tool-workpiece "welding" that ruins surface gloss in traditional carbide.

Low Cutting Resistance

Featuring the -PS breaker, this insert reduces radial cutting forces, making it perfect for slender shafts and thin-walled tubes where vibration is a risk.

Excellent Wear Resistance

Engineered for high-speed finishing, NS9530 maintains edge sharpness significantly longer than coated carbide when machining alloy steels.

Industrial Feedback

⭐⭐⭐⭐⭐ "Like a Mirror" - James H., UK
"Switched from coated carbide to NS9530 for our final pass. The surface finish is like a mirror. Client was extremely impressed."

⭐⭐⭐⭐⭐ "Perfect for Swiss-Type" - S. Tanaka, Japan
"Very sharp edges. Perfect for our small Citizen machines when we need high precision on alloy steel shafts."

⭐⭐⭐⭐⭐ "Outstanding Service" - Carlos V., USA
"Beyond Li supplied authentic Tungaloy stock quickly. These cermet inserts held up beautifully at 250m/min."

⭐⭐⭐⭐⭐ "Stable Chip Control" - L. Rossi, Italy
"The -PS breaker is great for shallow finishing. No long chips, just clean, broken chips and a perfect surface."

8. FAQ - Engineering Q&A

Q: Can I use cermet for stainless steel?

A: NS9530 is optimized for carbon and alloy steels. For stainless steel finishing, we recommend the AH725 carbide grade for better edge toughness.

Q: Should I use coolant with cermet?

A: Cermet can be used dry or wet. For the best gloss on steel, dry high-speed machining is often preferred to prevent thermal shock.

Q: Why is the 0.4mm radius better than 0.8mm for finishing?

A: A smaller radius like 0.4mm reduces radial cutting pressure, which prevents vibration and allows for finer profiling details.

Machining Tip: Maximize Cermet Gloss

To achieve the **ultimate surface finish**, ensure your cutting speed (Vc) is high enough to generate heat, which softens the material and allows the **cermet edge** to shear cleanly. Avoid cermet for heavy interrupted cuts as it is more brittle than carbide. **Tungaloy Japan** - Excellence in Precision.

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.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times. A tracking number is sent by email after shipment.
