Tungaloy TCMT110202-PS NS9530 Turning Insert
Super-Mirror Finishing | Advanced NS9530 Cermet Grade | 0.2mm Radius
How can I achieve a mirror-like surface finish on steel parts?
The Tungaloy TCMT110202-PS NS9530 is a specialized triangular indexable insert designed for the ultimate precision finishing of ISO P (Steel) materials. Unlike standard carbide, this insert utilizes the NS9530 Cermet grade, which provides exceptional resistance to oxidation and wear at high speeds. The -PS (Power Sharp) chipbreaker combined with a sharp 0.2mm corner radius allows for extremely fine depths of cut while maintaining strict dimensional tolerances. 100% Made in Japan, it is the industrial standard for aesthetic finishing and high-speed precision machining.
NS9530 Cermet Grade
A titanium-based cermet grade that offers superior chemical stability. It resists built-up edge (BUE) much better than carbide, ensuring long-lasting surface luster and accuracy.
Super Finishing -PS Breaker
The PS geometry is optimized for light depths of cut. It curls chips effectively at low feed rates, preventing the "bird-nesting" that ruins precision components.
0.2mm Ultra-Sharp Radius
The 02 radius is perfect for fine internal boring and external finishing where the cutting pressure must be minimized to avoid vibration and deflection.

Recommended Cutting Parameters (NS9530 Cermet)
-
Cutting Speed (Vc): 100 - 250 m/min (High Speed Recommended)
-
Feed Rate (f): 0.03 - 0.15 mm/rev
-
Depth of Cut (ap): 0.1 - 1.0 mm
*Machinist Advice: Cermet works best when used dry or with minimal lubrication to maintain high cutting temperatures that enable superior finishing results.*
4. Product Applications
- High-speed finishing of low to medium carbon steels.
- Final dimensioning of precision pins and miniature shafts.
- Internal finishing of small-diameter bores (minimum deflection).
- Replacing grinding operations with hard turning/finishing.
5. Tool Compatibility
Designed for Tungaloy / ISO boring bars and holders using the TCMT 1102 pocket size. Fits all standard STFCR/L external and internal holders.

Reviews from Precision Machine Shops
⭐⭐⭐⭐⭐ "Mirror Finish on 1045 Steel" - Hans W., Germany
"The NS9530 grade is incredible. We reached surface finishes we used to think only grinding could achieve. Exceptional."
⭐⭐⭐⭐⭐ "Perfect for Swiss-type CNC" - Jason M., USA
"Sharp edge and stable dimensions. We use these for finishing 5mm diameter steel shafts. Zero complaints."
⭐⭐⭐⭐ "Great Chip Evacuation" - Hiro L., Singapore
"The -PS breaker works perfectly at 0.05mm feed. Chips are small and don't tangle around the workpiece."
⭐⭐⭐⭐⭐ "Original Quality" - Fabio C., Italy
"Buying from CNCHome-Beyond was seamless. Fast shipping and the product is definitely 100% Tungaloy Japan."
⭐⭐⭐⭐⭐ "Longer Life than Carbide" - Ahmed K., UAE
"In high-speed finishing, this cermet lasts much longer than our previous PVD coated carbide inserts."
8. FAQ - Cermet Finishing Support
Q: Can I use this for Stainless Steel?
A: NS9530 is primarily optimized for ISO P (Steel). For Stainless Steel (ISO M), we recommend PVD grades like AH725 for better tool life, though cermet can provide a better finish on some stainless grades.
Q: Should I use coolant with cermet?
A: Cermet is sensitive to thermal shock. It is often recommended to use it dry or with high-pressure coolant. Intermittent coolant can cause micro-chipping.
Q: What does the 0.2mm radius change?
A: It reduces the tool contact area, lowering cutting force. This allows for extremely high-precision finishing on delicate or small-diameter workpieces.
Industrial Tip: Why Choose NS9530 Cermet over Carbide?
While **Carbide** (like AH725) is tough and versatile, **NS9530 Cermet** is chemically inert at high temperatures. This prevents the steel from "welding" to the tool edge, allowing you to maintain a high-gloss finish for much longer production cycles. For the best surface luster, **Tungaloy Japan Cermet** is the professional choice.
