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

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.
