Tungaloy TCMT110204-24 NS9530 Turning Insert
Precision Steel Finishing | Premium NS9530 Cermet | 0.4mm Corner Radius
What is the best cermet insert for high-quality surface finishes in steel?
The Tungaloy TCMT110204-24 NS9530 is a premium triangular turning insert designed for precision finishing of ISO P (Steel) and ISO K (Cast Iron). Utilizing the advanced NS9530 cermet grade, this insert offers exceptional chemical stability, effectively preventing built-up edge and oxidation during high-speed machining. The -24 chipbreaker combined with a 0.4mm corner radius ensures excellent chip evacuation and a mirror-like surface finish. 100% Made in Japan, it is the professional choice for CNC workshops demanding dimensional accuracy and surface integrity.
NS9530 Cermet Grade
A TiCN-based cermet grade providing a perfect balance of toughness and wear resistance. It maintains sharp edges longer than carbide, resulting in superior surface luster.
-24 Precision Breaker
The -24 geometry is optimized for medium-to-light finishing, reducing cutting forces and heat generation to prevent workpiece thermal deformation.
0.4mm Radius Stability
The 0.4mm (04) corner radius offers a robust cutting edge suitable for achieving high Ra surface quality in general-purpose steel finishing.

Recommended Cutting Parameters (NS9530)
-
Cutting Speed (Vc): 120 - 300 m/min
-
Feed Rate (f): 0.05 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 2.0 mm
*Expert Note: For cermet grades, avoid flood coolant. High speeds with an air blast result in the best tool life and surface finish.*

"Best cermet insert for steel. The 0.4mm radius is durable and the mirror finish it leaves is impressive."
8. FAQ - Turning Technical Support
Q: Why should I choose cermet over carbide for finishing?
A: Cermet (NS9530) has lower chemical affinity for steel, which prevents chip welding (built-up edge), resulting in a much smoother and shinier finish.
Q: Is this insert compatible with standard boring bars?
A: Yes, it follows the ISO standard TCMT 1102 dimensions. It fits any holder designed for a 1/4" (6.35mm) inscribed circle triangular insert.
Q: What is the benefit of the -24 chipbreaker?
A: The -24 is a versatile breaker that offers excellent chip control for finishing passes, reducing heat and improving surface Ra values.
Expert Tip: Maximizing Surface Shine
To get the best out of the **NS9530 Cermet**, increase your cutting speed (Vc). High speeds generate the necessary heat to make the cermet flow smoothly, while an air blast keeps the chips from scratching the new surface. Trust **Tungaloy Japan** for professional CNC finishing excellence.
