Tungaloy CCMT09T304-PS NS9530 Cermet Insert

Mirror Surface Quality | High-Speed Steel Turning | Advanced NS9530 Cermet

Why is NS9530 cermet the best for high-speed precision finishing?

The Tungaloy CCMT09T304-PS NS9530 is a premium uncoated cermet turning insert designed specifically for operators who prioritize a flawless surface finish and dimensional consistency. The NS9530 grade is a sophisticated cermet material that offers superior resistance to built-up edge (BUE) and oxidation, which are common issues when machining carbon and alloy steels. This indexable turning tool features the PS-style chipbreaker, a precision-ground geometry that ensures exceptional chip control at light depths of cut. With a balanced 0.4mm corner radius, it provides the perfect blend of edge strength and sharpness for high-end CNC machining. Made in Japan, it is the ultimate precision machining solution for high-efficiency production lines.

How does the PS geometry improve chip control?

The PS Chipbreaker is a precision finishing geometry that minimizes cutting resistance. By using a sharp rake angle and a specifically designed groove, it forces chips to curl and break even at shallow depths of cut. This long-tail keywords industry favorite prevents long, stringy chips from scratching your workpiece. When paired with the NS9530 cermet grade, which provides excellent thermal stability, the result is a significantly extended tool life and a high-speed machining performance that standard carbide cannot match.

Cermet NS9530: The Key to Mirror Finishes

Cermet is a ceramic-metal composite. Because it doesn't contain the same metallic binders as tungsten carbide, it has a very low affinity for steel. This means the material won't "stick" to the insert at high temperatures. For precision machining, this is the secret to achieving that "ground-like" surface finish on CNC turned parts without secondary operations.

What are the recommended speeds for NS9530?

Optimized for P (Steel) and K (Cast Iron) finishing:

• Cutting Speed (Vc): 100 - 350 m/min (Higher speed is better for cermet)
• Feed Rate (f): 0.05 - 0.15 mm/rev
• Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: Ensure your machine is running at high RPM to take full advantage of cermet's properties.*

Machinist Tip: Cermet vs. Carbide

For precision machining where Ra (surface roughness) is the priority, Cermet (NS9530) is the winner. It maintains edge sharpness at speeds where carbide begins to wear, ensuring longer tool life for finishing passes.
