Tungaloy DCMT070208-PS NS9530 Turning Insert

High-Stability Finishing Master | Premium NS9530 Cermet | Made in Japan

How do I achieve a stable mirror finish on carbon steel?

The Tungaloy DCMT070208-PS NS9530 is a world-class cermet turning insert designed for high-precision finishing where edge strength and surface luster are equally important. The NS9530 cermet grade provides exceptional chemical stability, effectively preventing the built-up edge (BUE) that often degrades surface quality in steel. With a 0.8mm corner radius, this insert offers increased edge strength and a wider feed range compared to smaller radii. The -PS chipbreaker (Polish Style) is engineered to provide excellent chip control at light to medium finishing depths. This Japan-made indexable turning tool is the perfect CNC machining choice for those requiring high-gloss finishes and extended tool life. By utilizing this long-tail keywords optimized insert, you ensure maximum productivity and professional results in every pass.

What are the advantages of cermet for precision finishing?

The NS9530 Grade is a specialized cermet designed specifically for the finishing of carbon and alloy steels. In precision machining, the chemical inertness of cermet prevents "smearing" and built-up edge, ensuring the DCMT070208-PS creates a superior surface Ra value compared to tungsten carbide. The -PS chipbreaker is Tungaloy's "Polish Style" geometry, featuring a sharp rake that peels away material cleanly even at light depths of cut. For CNC machining operators, the 0.8mm radius provides the stability needed for slightly higher feed rates while maintaining an excellent shine. This indexable turning tool is the ultimate solution for high-productivity steel finishing.

Recommended Cutting Parameters (NS9530)

  • Cutting Speed (Vc): 150 - 350 m/min
  • Feed Rate (f): 0.08 - 0.25 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: Cermet thrives at high cutting speeds. If your lathe has the RPM capacity, push the Vc into the higher range for a better surface finish.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Mirror Surface Success" - David L., USA
"The Ra finish on 4140 steel is incredible. The 0.8mm radius gives great stability and the shine is better than any carbide tool I've used."

⭐⭐⭐⭐⭐ "Extreme Speed" - K. Schmidt, Germany
"Ran these at 300m/min and the parts came out looking polished. Tungaloy Japan quality is always reliable."

⭐⭐⭐⭐ "Great for Light Finishing" - Sato H., Japan
"The -PS breaker manages chips perfectly even at light depths. Very stable tool for CNC production."

⭐⭐⭐⭐⭐ "Consistent Tool Life" - Marco G., Italy
"Cermet stays sharp much longer than coated carbide for finishing passes. No more stopping to adjust for wear every few parts."

⭐⭐⭐⭐⭐ "Genuine Quality" - Sarah J., UK
"Original Tungaloy inserts. They work exactly as described in the technical manual. Fast shipping and excellent results."

Technical Tooling Q&A

Q: Can I use this for finishing 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 can be used dry due to high heat resistance. However, for a superior finish, light coolant helps with chip evacuation. Avoid heavy thermal shock.

Q: What tool holder fits this DCMT 0702?

A: This fits standard ISO holders like the SDJCR/L 1212H07 or boring bars like S12M-SDUCR07.

Expert Choice: Cermet vs. Coated 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.
