Tungaloy TCMT16T302-PS NS9530 Turning Insert
High-Precision Mirror Finishing | Advanced NS9530 Cermet | 0.2mm Corner Radius
What is the sharpest cermet insert for precision finishing steel?
The Tungaloy TCMT16T302-PS NS9530 is a high-performance triangular turning insert designed for the ultimate precision finishing of ISO P (Steel). Built with the NS9530 Cermet grade, this tool offers exceptional chemical stability and oxidation resistance, ensuring a glossy surface finish that exceeds standard carbide performance. The 0.2mm corner radius (02) and the -PS "Power Sharp" chipbreaker provide the sharpest cutting edge for light depths of cut, making it the industrial standard for fine internal boring and external profile finishing. 100% Made in Japan, it delivers uncompromising dimensional accuracy for your CNC operations.
NS9530 Cermet Tech
A titanium-based cermet grade designed to withstand high-speed cutting while resisting built-up edge (BUE). Perfect for maintaining mirror-like surfaces on high-carbon and alloy steels.
-PS Power Sharp Breaker
The highly positive -PS geometry effectively breaks chips at low feed rates and small depths of cut, preventing the workpiece damage often caused by long, stringy chips.
0.2mm Precision Radius
The ultra-small radius reduces cutting pressure significantly, minimizing vibration and tool deflection in small boring bars or thin-walled components.

Global Machinist Reviews
⭐⭐⭐⭐⭐ "Mirror Surface" - Thomas B., Germany
"The NS9530 grade gives a shine that carbide cannot reach. 0.2mm radius is perfect for my fine pins."
⭐⭐⭐⭐⭐ "Best for Boring" - Hiroshi Y., Japan
"Stable performance in internal boring. Chips are small and evacuate perfectly. Authentic Tungaloy stock."
⭐⭐⭐⭐ "Great Service" - David R., USA
"Received original boxes in 5 days. These cermets last much longer in high-speed finishing runs."
⭐⭐⭐⭐⭐ "High Gloss Result" - Fabio M., Italy
"Exactly what we needed for the automotive shafts. Ra values are well within our tolerance now."
⭐⭐⭐⭐⭐ "Precision Choice" - Samuel L., Singapore
"The -PS breaker is very sharp. No vibration at all on the CNC lathe. Highly recommended partner."
8. FAQ - Professional Support
Q: Can I use this for Stainless Steel?
A: NS9530 is primarily for ISO P (Steel). For Stainless Steel (ISO M), we suggest PVD grades like AH725 to handle work-hardening better.
Q: Should I use coolant with cermet?
A: Cermet is sensitive to thermal shock. It's often better to cut dry or with high-pressure air to avoid micro-cracks on the edge.
Q: What is the benefit of the 0.2mm radius?
A: It allows for extremely fine detail and reduces cutting force, which prevents vibration in long boring applications.
Industrial Tip: Cermet NS9530 vs. Carbide
Select **Cermet NS9530** when your priority is a high-gloss surface and dimensional stability at high cutting speeds. Unlike carbide, cermet doesn't "weld" to the steel, keeping your tool edge sharp for longer production cycles. For precision machining, **Tungaloy Japan** is the professional choice.
