Tungaloy SCMT09T308-PS NS9530 Insert
High-Gloss Steel Finishing | -PS Precision Breaker | NS9530 Cermet Grade
What is the best cermet insert for mirror finishes on steel?
The Tungaloy SCMT09T308-PS NS9530 is a high-performance square cermet turning insert engineered for ultra-precision finishing of carbon and alloy steels. Utilizing the advanced NS9530 cermet grade, this insert provides superior chemical stability and oxidation resistance, ensuring an exceptional surface gloss that reduces the need for secondary grinding operations. The -PS chipbreaker is specialized for light-to-medium finishing, offering excellent chip control even at low depths of cut. Made in Japan, this CNC cermet insert is the industry standard for automotive parts and precision instrument manufacturing.
NS9530 Cermet Grade
Excellent balance of wear resistance and fracture toughness. Specifically designed to prevent built-up edge and maintain dimensional accuracy over long runs.
-PS High-Precision Breaker
The positive geometry effectively reduces cutting forces and heat generation, resulting in a smooth, vibration-free cutting action.
Extended Corner Strength
The 0.8mm corner radius provides enhanced edge strength, allowing for slightly higher feed rates without compromising the mirror-like finish.

Verified Global Feedback
⭐⭐⭐⭐⭐ "Mirror Surface" - David R., UK
"Switched from coated carbide to this NS9530 cermet for my finish passes. The surface finish is literally like a mirror. No more polishing!"
⭐⭐⭐⭐⭐ "Excellent Tool Life" - Hans K., Germany
"The -PS breaker handles chips perfectly on 1045 steel. Dimensions stayed within 0.01mm across a batch of 500 parts."
⭐⭐⭐⭐ "Great for Finishing" - Y. Tanaka, Japan
"Very high precision. Tungaloy cermet is our go-to for automotive finishing operations."
⭐⭐⭐⭐⭐ "Authentic Quality" - Robert S., USA
"Genuine Tungaloy inserts. Shipping was fast and the performance on alloy steel is outstanding."
⭐⭐⭐⭐⭐ "Top Performance" - S. Lim, Singapore
"Reliable results every time. The 0.8mm radius is strong enough for light semi-finishing too."
8. FAQ - Professional Support
Q: Can I use cermet for interrupted cuts?
A: Cermet is more brittle than carbide. It is highly recommended for continuous cutting. For heavy interruptions, use T9125 carbide instead.
Q: Is NS9530 better than NS9530-coated?
A: NS9530 is a premium uncoated cermet that provides a sharper edge and higher gloss. For extremely high speeds, the GT9530 (coated version) might offer slightly more wear resistance.
Q: Will this fit my standard SSDCN holder?
A: Yes, it is a standard ISO SCMT 09T3 size and is fully compatible with SSDCN series holders.
Expert Insight: The Cermet Advantage
In high-speed precision turning, cermet (Ceramic + Metal) resists the chemical reaction between the tool and steel. This prevents "smearing" and built-up edge, which is why the NS9530 grade produces such a bright surface finish compared to traditional coated carbide. For parts where aesthetics and precision are everything, the SCMT09T308-PS is the industrial professional's choice.
