Tungaloy CCMT09T302-PS NS9530 Cermet Insert

High-Speed Precision | Mirror Surface Finish | Premium NS9530 Grade

Why is NS9530 the ultimate choice for high-speed precision finishing?

The Tungaloy CCMT09T302-PS NS9530 is a world-class uncoated cermet turning insert specifically engineered for achieving superior surface quality on steel workpieces. The NS9530 grade is a titanium-based cermet that offers an optimized balance of high hardness and fracture toughness. Because cermet has a significantly lower chemical affinity for steel than tungsten carbide, it prevents the "welding" of chips to the cutting edge, effectively eliminating built-up edge (BUE). This indexable turning tool features the PS-style chipbreaker, a ground geometry designed for light finishing passes. With its sharp 0.2mm corner radius, it is the ideal precision machining tool for small components or applications requiring minimal cutting pressure. Made in Japan, this insert ensures unmatched tool life and consistent dimensions in high-efficiency CNC machining environments.

What are the benefits of the PS Chipbreaker at high speeds?

The PS Chipbreaker is a ground finishing geometry optimized for light cutting depths. It features a sharp rake angle that drastically reduces cutting resistance and heat generation. This is critical for precision machining in CNC machining when you need to avoid vibration or deflection on thin-walled parts. For those searching for long-tail keywords such as "high speed cermet finishing," the combination of the sharp edge and the NS9530 grade provides a flawless finish that often removes the need for grinding or polishing.

Advanced NS9530 Cermet Properties

The NS9530 grade is designed for chemical stability. Because it is non-metallic (ceramic-metal), it can withstand higher temperatures than standard carbide without deforming. This indexable turning tool maintains its sharp edge over much longer production cycles, ensuring that your parts stay within tolerance from the first piece to the last. This translates into longer tool life and less machine downtime for insert changes.

What are the recommended speeds and feeds for NS9530?

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

• Cutting Speed (Vc): 100 - 350 m/min (High speed is better for Cermet)
• Feed Rate (f): 0.03 - 0.12 mm/rev
• Depth of Cut (ap): 0.1 - 1.0 mm

*Note: Cermet is more sensitive to thermal shock than carbide; avoid heavy interrupted cuts for best results.*

Expert Tip: Cermet vs. Carbide

When precision machining demands the best possible surface roughness (Ra), Cermet (NS9530) is the winner. It provides higher thermal stability at high speeds, ensuring your dimensions stay consistent throughout the batch while offering a significantly longer tool life for finishing passes.
