Tungaloy TCMT090202-24 NS9530 Turning Insert
Precision Steel Finishing | Premium NS9530 Cermet | 0.2mm Radius
How do I achieve the best surface finish on steel parts?
The Tungaloy TCMT090202-24 NS9530 is a high-precision triangular turning insert engineered for high-gloss finishing of ISO P (Steel) and ISO K (Cast Iron). Featuring the NS9530 cermet grade, this insert provides superior chemical stability and resistance to built-up edge, which is essential for maintaining dimensional accuracy and achieving a mirror-like surface luster. The 0.2mm corner radius and -24 chipbreaker allow for exceptionally light depths of cut and precise chip control. 100% Made in Japan, it is the industrial standard for fine-turning applications.
NS9530 Cermet Grade
A versatile uncoated cermet grade with incredible fracture resistance. It maintains sharp cutting edges much longer than traditional carbide during finishing passes.
-24 Precision Chipbreaker
Designed for medium-to-light cutting, the -24 breaker minimizes cutting forces and prevents chip tangling on delicate workpieces.
Ultra-Sharp 0.2mm Radius
The small 0.2mm (02) corner radius is perfect for sharp corners and internal boring where low radial pressure is required to avoid vibration.

Global Professional Reviews
⭐⭐⭐⭐⭐ "Mirror Finish Success" - Hans W., Germany
"The NS9530 cermet is fantastic. We used this for a batch of steel shafts and the finish was mirror-like. Very sharp edges."
⭐⭐⭐⭐⭐ "Perfect for Boring" - Sarah M., UK
"The 0.2mm radius is perfect for my small boring operations. No vibration and the tool life is impressive for finishing."
⭐⭐⭐⭐ "Great Japanese Quality" - H. Sato, Japan
"Consistent size control. The -24 chipbreaker handles small depths of cut very well. Original Tungaloy is reliable."
⭐⭐⭐⭐⭐ "B2B Fast Service" - Lim K., Singapore
"CNCHome-Beyond provided authentic stock quickly. This TCMT 090202 is our standard for fine finishing."
⭐⭐⭐⭐⭐ "Precision Choice" - Luca F., Italy
"Excellent value. The cermet grade stays sharp much longer than coated carbide when doing final passes on mild steel."
8. FAQ - Turning Support
Q: Why use cermet instead of carbide for steel?
A: Cermet (NS9530) has a low chemical affinity for steel, which means less chip welding (built-up edge) and a much cleaner surface finish.
Q: Can I use this for roughing?
A: No, cermet is brittle compared to carbide. It should be reserved for finishing or light cutting where surface quality and size control are the priorities.
Q: Does this fit my boring bar?
A: This insert fits any TCMT 0902 / TCMT 1.8(1.5) size holder. Please check your tool holder's pocket size before ordering.
Expert Tip: Cermet Finishing
The **NS9530 Cermet** is your best friend for dimensional accuracy. It thrives at higher speeds where carbides might overheat. For the best result, keep a consistent, light feed and use an air blast. Trust **Tungaloy Japan** for high-precision components. Avoid using this for interrupted cuts.
