Tungaloy TCMT110202-24 NS9530 Turning Insert
High-Precision Steel Finishing | Premium NS9530 Cermet | 0.2mm Corner Radius
How do I get a mirror surface finish on CNC turned steel parts?
The Tungaloy TCMT110202-24 NS9530 is a high-precision triangular turning insert specifically engineered for the high-gloss finishing of ISO P (Steel) and ISO K (Cast Iron) workpieces. Utilizing the NS9530 cermet grade, this insert provides superior chemical stability and resistance to built-up edge, which is essential for maintaining tight tolerances and achieving high-quality surface integrity. The -24 chipbreaker combined with a 0.2mm radius allows for extremely fine depths of cut, making it the perfect choice for final precision passes. 100% Made in Japan, it ensures stable tool life and Japanese manufacturing excellence.
NS9530 Cermet Grade
A premier TiCN-based cermet that resists oxidation and adhesion. It maintains a sharp cutting edge longer than carbide, ensuring consistent surface luster across large batches.
-24 Precision Breaker
The -24 chipbreaker is optimized for medium-to-light finishing. It minimizes radial cutting forces, effectively preventing chatter and vibration in slim workpieces.
Ultra-Fine 0.2mm Radius
The small 0.2mm (02) corner radius is designed for precision cornering and internal boring where minimal cutting pressure is required for Ra accuracy.

Machining Success Stories
⭐⭐⭐⭐⭐ "Perfect Gloss" - Dieter S., Germany
"We replaced our coated carbide with this NS9530 cermet for the final pass on steel parts. The gloss is significantly better and Ra values are spot on."
⭐⭐⭐⭐⭐ "Great for Small Boring" - Mike L., UK
"The 0.2 radius on the TCMT110202-24 is exactly what we needed for fine internal boring. Zero vibration and clean chips."
⭐⭐⭐⭐ "Consistent Quality" - T. Yamamoto, Japan
"Reliable results batch after batch. The finish quality is maintained even after several hours of cutting."
⭐⭐⭐⭐⭐ "Fast Delivery" - Lim W., Singapore
"Ordered for our production line and arrived quickly. These are genuine Tungaloy inserts and perform exactly as expected."
⭐⭐⭐⭐⭐ "Mirror Surface" - Marco V., Italy
"The best insert for finishing passes. We achieve a mirror-like surface on alloy steel with the NS9530 grade. Five stars!"
8. FAQ - Turning Insights
Q: Is cermet better than carbide for finishing?
A: Yes, cermet has a low chemical affinity for steel, which prevents built-up edge and oxidation, resulting in a much smoother and shinier finish.
Q: Can I use this for rough turning?
A: Cermet is more brittle than carbide. It is highly recommended to reserve these for finishing or light continuous cutting to avoid chipping.
Q: What tool holder do I need?
A: This insert fits any TCMT 1102 or TCMT 21.5 size holder. Always ensure the pocket is clean before mounting to maintain the precision of the 0.2mm radius.
Expert Tip: Maximizing Cermet Performance
The **NS9530 Cermet** thrives at high cutting speeds. To achieve that signature mirror finish, maintain a steady feed and avoid using flood coolant if possible—use an air blast to clear chips. This prevents thermal shock and prolongs the sharp edge life. Trust **Tungaloy Japan** for professional CNC results.
