Tungaloy DCMT070202-PS NS9530 Turning Insert

Ultra-Fine Finishing Master | Premium NS9530 Cermet | Made in Japan

How can I achieve a high-gloss finish on steel without polishing?

The Tungaloy DCMT070202-PS NS9530 is a specialized cermet turning insert engineered for high-precision finishing where surface aesthetics are paramount. Utilizing the advanced NS9530 cermet grade, this insert offers superior chemical stability and resistance to built-up edge (BUE), which is the primary cause of dull surface finishes in steel. The -PS chipbreaker is specifically optimized for light-duty finishing, providing exceptional chip evacuation at very small depths of cut. This Japan-made indexable turning tool with a sharp 0.2mm radius is the ideal CNC machining solution for intricate components in the medical and watchmaking industries. By using this long-tail keywords optimized insert, you can ensure a consistent tool life and a brilliant mirror finish on every part.

Why is the NS9530 cermet better for steel finishing than carbide?

The NS9530 Grade is a premium cermet material that combines the hardness of ceramics with the toughness of metal. In precision machining, cermet is preferred for finishing because it has a lower chemical affinity for steel, meaning parts won't stick to the tool. The -PS chipbreaker (Polish Style) is designed with a very sharp edge and a specific rake profile to break chips even at depths as shallow as 0.1mm. For CNC machining operators, this indexable turning tool provides a significant advantage in maintaining Ra values and dimensional accuracy throughout long production runs without the frequent offsets required by traditional carbide.

Recommended Cutting Parameters (NS9530)

  • Cutting Speed (Vc): 150 - 350 m/min
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.1 - 1.0 mm

*Optimization Tip: Cermet performs best at high speeds. Ensure your machine can reach the recommended RPM to achieve the best surface shine.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Mirror Surface Success" - Liam W., USA
"The Ra finish on 1045 steel is incredible. The PS breaker handles light cuts much better than standard finishing inserts. No more stringy chips."

⭐⭐⭐⭐⭐ "Extreme Precision" - Hans M., Germany
"Tungaloy Japan quality. The 0.2mm radius is perfect for small intricate parts. Stable tool life and very sharp edge."

⭐⭐⭐⭐ "Great for Swiss Lathes" - Sato K., Japan
"Very low cutting force. Ideal for our precision CNC lathes when turning slender shafts. The cermet stays clean throughout the run."

⭐⭐⭐⭐⭐ "Better than Carbide" - Luca B., Italy
"Replaced my coated carbide with NS9530 for the final pass. The surface luster is night and day. Much brighter finish."

⭐⭐⭐⭐⭐ "Original & Reliable" - James P., UK
"Authentic Tungaloy. Fast delivery and perfect performance. These inserts are a staple for our finishing operations."

Technical Tooling Q&A

Q: Can I use this for stainless steel?

A: NS9530 is a steel specialist. While it can handle very light finishing on some stainless, we recommend a PVD carbide grade for sticky materials like 304 or 316.

Q: Does cermet require coolant?

A: Cermet has high heat resistance and can be used dry. However, for the best surface luster, a light flow of coolant helps evacuate chips and maintain temperature stability.

Q: What tool holder series fits this DCMT 0702?

A: This fits standard ISO holders like the SDJCR/L 1010 or 1212 series, and internal boring bars like S...-SDUCR07.

Expert Choice: Cermet vs. Coated Carbide

For precision machining, Cermet (NS9530) provides much higher resistance to chemical wear than Tungsten Carbide. If you need a mirror-finish surface and high dimensional repeatability, switching to cermet is the most cost-effective upgrade for your CNC shop.

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.

What is your international shipping policy and typical lead time for orders?
