Tungaloy TPMT090204-PS NS9530 Insert

Premium Cermet Grade | -PS Mirror Finishing Geometry | Made in Japan

What is the best cermet insert for a mirror finish on steel?

The Tungaloy TPMT090204-PS NS9530 is an industrial-grade triangular cermet insert designed for high-speed finishing where surface quality is the top priority. Unlike traditional carbide, the NS9530 cermet grade provides exceptional resistance to built-up edge (BUE) and oxidation, allowing for high-gloss, mirror-like finishes on carbon and alloy steels. The -PS (Positive Sharp) chipbreaker is engineered to minimize cutting forces and ensure clean chip evacuation at light depths of cut. 100% Made in Japan, it is the ultimate choice for precision CNC manufacturing.

NS9530 Cermet Grade

A non-coated cermet grade that maintains a sharp cutting edge much longer than carbide. It prevents material welding, ensuring high-dimensional accuracy and Ra values.

-PS High-Precision Edge

The PS geometry features a sharp rake angle specifically optimized for finishing passes (ap < 1.0mm). It lowers machine vibration and heat generation.

Superior Surface Quality

Because cermet has a low affinity for steel, it produces a superior finish compared to coated carbide, often eliminating the need for subsequent grinding.

User Testimonials

⭐⭐⭐⭐⭐ "Incredible Finish!" - David L., USA
"The NS9530 cermet is miles ahead of coated carbide for finishing. We get a near-mirror finish on carbon steel parts without any grinding."

⭐⭐⭐⭐⭐ "Perfect for Swiss Lathes" - Hans B., Germany
"Very stable geometry. The -PS breaker handles the chips beautifully on our Star CNCs. Original Tungaloy quality."

⭐⭐⭐⭐ "Great Service" - Marco S., Italy
"Ordered for a precision job in Milan. Shipping was fast. The inserts perform exactly as expected for high-speed finishing."

⭐⭐⭐⭐⭐ "Authentic Quality" - Robert T., UK
"Verified genuine Tungaloy. The NS9530 grade is my go-to for bearing steel. Highly recommended B2B supplier."

⭐⭐⭐⭐⭐ "Stable & Sharp" - Jun H., South Korea
"Sharp edge stays clean even at high RPMs. Better Ra than the AH725 for steel applications. Great value."

8. FAQ - Professional Support

Q: Why use Cermet instead of Coated Carbide?

A: Cermet (NS9530) has a lower chemical affinity for steel, which prevents chip welding. This leads to a much better surface finish and longer tool life in continuous finishing.

Q: Is this insert good for stainless steel?

A: For stainless steel, we recommend the AH725 grade. NS9530 is best for carbon steel, alloy steel, and ductile cast iron.

Q: Can I use this for interrupted cuts?

A: Cermet is more brittle than carbide. It is highly recommended for continuous cutting. For heavy interruptions, consider a toughened carbide grade.

Tech Tip: Achieving the Perfect Ra

The **NS9530 cermet** is designed for the "sweet spot" of CNC finishing. By maintaining high surface speeds (Vc > 200m/min) and using the **-PS breaker**, you can achieve surface finishes that rival grinding. **Tungaloy Japan** - Excellence in every turn.

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.
