Tungaloy TCMT110208-24 NS9530 Turning Insert
Durable Steel Finishing | Premium NS9530 Cermet | 0.8mm Corner Radius
What is the most durable cermet insert for steel finishing?
The Tungaloy TCMT110208-24 NS9530 is a high-performance triangular turning insert designed for professional-grade finishing of ISO P (Steel) and ISO K (Cast Iron). Featuring the advanced NS9530 cermet grade, this tool provides excellent chemical stability and heat resistance, which is critical for achieving mirror-like surface finishes at high cutting speeds. The 0.8mm corner radius offers enhanced edge strength compared to smaller radii, making it ideal for continuous finishing where dimensional consistency is paramount. 100% Made in Japan, it ensures the highest level of machining precision.
NS9530 Cermet Grade
A premier TiCN-based cermet that prevents chip welding and oxidation. It maintains sharp cutting edges much longer than coated carbide for high-speed finishing.
-24 Universal Finishing Breaker
The -24 geometry is engineered to reduce cutting resistance while providing excellent chip control during light-to-medium finishing passes.
0.8mm Robust Radius
The 0.8mm (08) corner radius provides a stronger edge and allows for higher feed rates while maintaining beautiful surface Ra values.

Recommended Cutting Parameters (NS9530)
-
Cutting Speed (Vc): 120 - 320 m/min
-
Feed Rate (f): 0.08 - 0.28 mm/rev
-
Depth of Cut (ap): 0.2 - 2.5 mm
*Machinist Note: Increase Vc for higher gloss results. Cermet is best used with an air blast rather than high-pressure coolant to avoid thermal cracking.*
4. Product Applications
- High-precision external finishing of low and medium carbon steels.
- Final machining of automotive components and axles.
- Boring operations where Ra surface quality is non-negotiable.
- Finishing alloy steels with high heat generation.
5. Tool Compatibility
Fits all standard Tungaloy / ISO tool holders designed for TCMT 1102 inserts (6.35mm IC). Compatible with a wide variety of internal boring bars and external turning shanks.

8. FAQ - Technical Support
Q: Can I use this for interrupted cutting?
A: Cermet is more brittle than carbide. It is generally recommended for continuous light cutting or finishing passes to prevent edge chipping.
Q: What is the benefit of the 0.8mm radius vs 0.4mm?
A: The 0.8mm radius offers a stronger edge and better heat dissipation. It also allows for higher feed rates while maintaining excellent surface quality.
Q: Do I need coolant with NS9530?
A: Dry machining with an air blow is often superior for cermet. It prevents thermal shock, which can lead to micro-cracks on the sharp edge.
Expert Tip: Optimizing Surface Shine
The **NS9530 Cermet** thrives at high cutting speeds (Vc). Increasing speed allows the material to flow smoothly over the sharp cermet edge, resulting in that signature high-gloss finish. For the best dimensional accuracy, keep your depth of cut consistent. Trust **Tungaloy Japan** for industrial-grade precision.
