Tungaloy TCMT110208-PS NS9530 Turning Insert

High-Gloss Steel Finishing | NS9530 Cermet Grade | 0.8mm Corner Radius

How do I get a mirror surface finish on steel at higher feed rates?

The Tungaloy TCMT110208-PS NS9530 is a high-performance triangular cermet insert designed specifically for finishing and semi-finishing of ISO P (Steel). Utilizing the NS9530 Cermet grade, this insert provides superior chemical stability compared to standard carbide, effectively preventing built-up edge (BUE) and oxidative wear. The 0.8mm corner radius (08) offers enhanced edge strength and allows for slightly higher feed rates while maintaining a smooth surface finish. Equipped with the -PS (Power Sharp) chipbreaker, it ensures excellent chip control even at light depths of cut. 100% Made in Japan, it is the professional choice for high-speed CNC precision turning.

NS9530 Cermet Grade

This TiCN-based cermet grade is highly resistant to crater wear and oxidation. It maintains a sharp edge at high temperatures, which is essential for achieving a high-gloss, mirror-like finish on steel parts.

-PS High-Precision Breaker

The -PS chipbreaker features a highly positive geometry that reduces cutting force and vibrations. It is optimized for finishing passes, providing clean chip evacuation without damaging the workpiece.

0.8mm Radius Strength

The 0.8mm radius provides significantly more durability than a 0.2mm or 0.4mm tip. It is ideal for parts requiring better heat dissipation and a more robust cutting edge during continuous finishing.

3. Technical Specifications: Metric vs. Imperial

Parameter Metric (ISO) Imperial Equivalent
Cutting Edge Length (L) 11.0 mm TCMT 21.52
Inscribed Circle (IC) 6.35 mm 1/4"
Thickness (S) 2.38 mm 3/32"
Corner Radius (RE) 0.8 mm 1/32"

Recommended Cutting Parameters (NS9530 Cermet)

  • Cutting Speed (Vc): 120 - 300 m/min (Optimum for Steel)
  • Feed Rate (f): 0.08 - 0.25 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Optimization Tip: Cermet inserts thrive in high-speed, light-load conditions. Use dry or with air-blow for the best surface finish to avoid thermal micro-cracking.*

4. Product Applications

  • Final finishing of automotive carbon steel components.
  • Boring high-precision internal holes in alloy steel.
  • Production of small shafts with high dimensional accuracy.
  • Applications where secondary grinding needs to be eliminated.

5. Tool Compatibility

Compatible with standard Tungaloy / ISO boring bars and turning holders designed for TCMT 1102 size pockets. Fits standard S-STFCR/L holders.

Reviews from Professional Workshops

⭐⭐⭐⭐⭐ "Mirror Surface" - Hans K., Germany
"The surface finish on 4140 steel is better than anything else we've tried. The 0.8 radius is much tougher for our production runs."

⭐⭐⭐⭐⭐ "Consistent Quality" - James W., USA
"Tungaloy cermet is very predictable. We get the same diameter on part #1 as part #100. Great service from CNCHome-Beyond."

⭐⭐⭐⭐ "Great for Boring" - Lin Y., Singapore
"Using this in an internal boring bar. Chips are small and evacuate perfectly. No scratches on the bore."

⭐⭐⭐⭐⭐ "Original Stock" - Sandro P., Italy
"Received original Japanese boxes. Performance is exactly what we expect from Tungaloy. Fast shipping to Europe."

⭐⭐⭐⭐⭐ "Super High Speed" - Arjun R., India
"We run this at high RPM and it stays sharp. Surface shine is incredible, almost like a ground part."

8. FAQ - Cermet Finishing Solutions

Q: Can I use NS9530 for interrupted cuts?

A: Cermet is generally more brittle than carbide. While it can handle very light interruptions, it is primarily designed for continuous finishing. For heavy interruptions, consider a PVD grade like AH725.

Q: Why choose the 0.8mm radius over 0.4mm?

A: The 0.8mm radius (08) offers more tip strength and allows for higher feed rates to maintain the same theoretical surface finish, which improves productivity.

Q: Does this fit standard STFCR boring bars?

A: Yes, it fits all standard STFCR/L holders that take a TCMT 1102 (or 21.5) size insert.

Tech Tip: Achieving the Best Mirror Finish

For the highest gloss, use **Cermet NS9530** at high cutting speeds (above 180 m/min). This ensures the material flow is smooth and prevents "tearing" the steel surface. Unlike carbide, cermet won't bond with the steel, leaving the workpiece bright and dimensionally perfect. **Tungaloy Japan** is the industrial standard for finishing.

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.
