Tungaloy TCMT110204-PS NS9530 Turning Insert
Premium Cermet Grade | High-Speed Steel Finishing | 0.4mm Radius
What is the best cermet insert for achieving a mirror finish on steel?
The Tungaloy TCMT110204-PS NS9530 is a premier triangular indexable insert engineered for the high-precision finishing of ISO P (Steel) materials. Unlike traditional carbide, the NS9530 Cermet grade provides exceptional chemical stability and resistance to oxidation, making it the ideal choice for high-speed machining where surface luster is critical. The -PS (Power Sharp) chipbreaker is specifically designed to handle light depths of cut, ensuring excellent chip control and preventing surface damage. 100% Made in Japan, this tool is the standard for CNC operators requiring dimensional accuracy and aesthetic brilliance.
NS9530 Cermet Grade
A titanium-based cermet that resists built-up edge (BUE). It maintains a sharp cutting edge much longer than coated carbide in high-speed finishing, resulting in superior surface Ra values.
-PS Finishing Breaker
The "Power Sharp" geometry features a highly positive rake angle. This reduces cutting force and vibrations, which is essential for thin-walled parts and small-diameter boring.
Precision 0.4mm Radius
The 0.4mm (04) radius provides a perfect balance between edge strength and the ability to machine fine corners, ideal for precision finishing of complex steel geometries.

What Machinists Are Saying
⭐⭐⭐⭐⭐ "Best Surface Finish" - Klaus M., Germany
"We switched to NS9530 for our steel pins. The cermet grade gives a shine that carbide just can't match. Great quality."
⭐⭐⭐⭐⭐ "Precision at High Speed" - Steve D., USA
"Running these at 200 m/min on a CNC lathe. Dimensions are consistent box after box. Tungaloy Japan is reliable."
⭐⭐⭐⭐ "Great Chip Control" - Taro H., Japan
"The -PS breaker is very sharp. Chips are broken into small 6-shapes even at a very small depth of cut."
⭐⭐⭐⭐⭐ "Perfect B2B Experience" - Marcus V., Italy
"Fast delivery and genuine product. These inserts are excellent for finishing our stainless workpieces too."
⭐⭐⭐⭐⭐ "Mirror Surface" - Wei L., Singapore
"The 0.4 radius is perfect for fine detail. The surface gloss is amazing, almost like it was ground."
8. FAQ - Precision Machining Support
Q: Is NS9530 better than AH725 for steel?
A: NS9530 (Cermet) is superior for high-speed finishing and achieving a high-gloss surface. AH725 (PVD Carbide) is tougher and better for semi-finishing or interrupted cuts.
Q: Can I use this for boring small holes?
A: Absolutely. The -PS breaker reduces cutting pressure, making it an excellent choice for boring applications to minimize vibration.
Q: Does this fit my S-STFCR11 holder?
A: Yes, TCMT 1102 series is the standard size for all STFCR/L 11 style turning and boring tools.
Machinist Tip: Cermet vs. Carbide
For the ultimate surface finish and long tool life in high-speed finishing, choose **NS9530 Cermet**. It prevents workpiece material from welding to the edge, keeping parts clean and bright. For high-precision steel turning, **Tungaloy Japan** is the professional choice.
