Tungaloy DCMT070204-PS NS9530 Turning Insert

Mirror Finish Specialist | Advanced NS9530 Cermet | Made in Japan

What is the best cermet insert for high-gloss steel finishing?

The Tungaloy DCMT070204-PS NS9530 is a premium cermet turning insert engineered for precision finishing where surface aesthetics and dimensional accuracy are critical. Utilizing the NS9530 cermet grade, this insert offers exceptional chemical stability and resistance to oxidation, effectively eliminating "built-up edge" (BUE) common in steel machining. The -PS chipbreaker (Polish Style) features a sharp, positive rake angle designed for light-duty finishing, ensuring excellent chip evacuation even at extremely small depths of cut. This Japan-made indexable turning tool with a 0.4mm radius is the ideal CNC machining solution for shops looking to achieve mirror-like finishes. By implementing this long-tail keywords optimized insert, you can drastically reduce secondary polishing time and enhance overall tool life.

Why choose NS9530 cermet for high-speed steel finishing?

The NS9530 Grade is a specialized cermet (ceramic-metal composite) that maintains high hardness at elevated temperatures, far outperforming standard carbide in finishing steel. In precision machining, the chemical inertness of cermet prevents work material from welding to the edge. The -PS chipbreaker is Tungaloy's "Polish Style" geometry, which utilizes a sharp rake to peel away thin chips smoothly. For CNC machining operators, this indexable turning tool ensures consistent Ra values and reduces the frequency of tool offsets, making it a highly reliable component for high-production environments.

Recommended Cutting Parameters (NS9530)

  • Cutting Speed (Vc): 150 - 350 m/min
  • Feed Rate (f): 0.05 - 0.20 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: Cermet thrives at higher speeds. For the best surface finish, don't be afraid to push the Vc into the upper range.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Brilliant Finish" - Alexander R., USA
"The Ra finish on alloy steel is incredible. The PS breaker handles light finishing cuts better than any carbide I've tried. No more polishing."

⭐⭐⭐⭐⭐ "True Japan Quality" - M. Lehmann, Germany
"Tungaloy NS9530 is my standard for steel. Predictable tool life and consistent tolerances. Perfect for CNC lathes."

⭐⭐⭐⭐ "Great Chip Control" - Sato T., Japan
"The -PS geometry is very sharp. Even at small ap, the chips are broken perfectly. Highly recommended for precision components."

⭐⭐⭐⭐⭐ "High Speed Performance" - Luca V., Italy
"Ran these at 300 m/min all day. The surface shine is impressive and the dimensions don't drift. Excellent cermet grade."

⭐⭐⭐⭐⭐ "Reliable and Authentic" - Sarah W., UK
"Original Tungaloy inserts. They work exactly as described in the technical manual. Fast shipping and great results."

Technical Tooling Q&A

Q: Can I use this for stainless steel?

A: NS9530 is optimized for carbon and alloy steels. For stainless steel, we recommend PVD-coated carbide like the SH730 or AH series for better toughness.

Q: Does cermet require coolant?

A: Cermet can be used dry due to its high heat resistance. However, for a superior finish and better chip evacuation, light coolant is fine. Avoid thermal shock.

Q: Which tool holder fits this DCMT 0702?

A: This fits standard ISO holders like the SDJCR/L 1212 or 1616 series, as well as internal boring bars (S...-SDUCR07).

Expert Tip: Cermet vs. Carbide for Ra Finish

In precision machining, Cermet (NS9530) provides much higher resistance to chemical wear than Tungsten Carbide. This results in the brilliant "high-gloss" finish that your customers expect, while maintaining tighter tolerances for longer periods.

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.
