Tungaloy DCMT11T302-PS NS9530 Turning Insert

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

How do I get a mirror finish on carbon steel parts?

The Tungaloy DCMT11T302-PS NS9530 is a high-performance cermet turning insert specifically engineered for precision finishing operations. Unlike traditional tungsten carbide, the NS9530 cermet grade provides exceptional chemical stability and resistance to built-up edge (BUE), which is critical for maintaining high-luster surfaces on steel. The -PS chipbreaker (Polish Style) features a sharp cutting edge and optimized geometry that ensures superior chip control even at extremely light depths of cut. This Japan-made indexable turning tool is the ideal choice for CNC machining shops looking to eliminate secondary polishing steps. By integrating this long-tail keywords optimized insert into your workflow, you guarantee consistent tool life and unmatched part quality.

What are the advantages of cermet for precision finishing?

The NS9530 Grade is a specialized cermet designed specifically for the high-speed finishing of carbon and alloy steels. In precision machining, cermet's low affinity for steel prevents the welding of chips to the cutting edge. The -PS chipbreaker (Polish Style) utilizes a sharp, positive rake that "peels" the material cleanly, resulting in the brilliant surface luster that Tungaloy is famous for. For CNC machining operators, this indexable turning tool offers much tighter tolerance control over long production runs than standard carbide inserts, making it a staple for high-quality finishing passes.

Recommended Cutting Parameters (NS9530)

  • Cutting Speed (Vc): 120 - 320 m/min
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.1 - 1.2 mm

*Pro Tip: Cermet is heat-resistant but can be brittle. Avoid interrupted cuts and ensure high cutting speeds to maximize surface brightness.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Mirror Finish Specialist" - James D., USA
"We turn small precision pins and the NS9530 gives us a mirror finish that standard carbide just can't touch. Very satisfied."

⭐⭐⭐⭐⭐ "Extreme Precision" - F. Schneider, Germany
"Tungaloy's cermet grade is top-tier. The 0.2 radius is very sharp and the dimensions stay consistent all day. Great tool life."

⭐⭐⭐⭐ "Great Chip Control" - Hiroshi T., Japan
"The -PS geometry is perfect for our light finishing passes. Even at 0.1mm depth, the chips break properly. Excellent for CNC Lathes."

⭐⭐⭐⭐⭐ "High Gloss Surface" - Luca M., Italy
"Used this on alloy steel and the surface Ra was impressive. Much better than the competitors for finishing."

⭐⭐⭐⭐⭐ "Original Quality" - Sarah L., UK
"Authentic Tungaloy inserts. They work exactly like the catalog says. Fast delivery and reliable performance."

Technical Tooling Q&A

Q: Can I use this for finishing stainless steel?

A: NS9530 is a steel specialist. While it can do light work on stainless, it is not recommended for sticky materials like 304/316 where PVD carbide is better.

Q: Does cermet require coolant?

A: Cermet can be used dry due to high heat resistance. For a mirror finish, light coolant helps with chip evacuation, but avoid thermal shock (on/off flow).

Q: What tool holder fits this DCMT 11T3?

A: This fits standard ISO holders like the SDJCR/L 1212 or 1616, and internal boring bars like S...-SDUCR/L.

Expert Tip: Cermet vs. Carbide for Ra Finishing

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.
