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.

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.*

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.
