Tungaloy TNGG160404R-C NS9530 Turning Insert
Precision Cermet Grade | NS9530 Mirror Finish | 0.4mm Right-Hand Radius
Which cermet insert is best for achieving a mirror finish on steel parts?
The Tungaloy TNGG160404R-C NS9530 is a high-precision right-hand cermet turning insert specifically engineered for the finishing of ISO P (Steel) and ISO M (Stainless Steel). Powered by the NS9530 uncoated cermet grade, this tool provides exceptional chemical stability and resistance to oxidation. The 0.4mm corner radius (04) combined with the -C chipbreaker ensures high-gloss surface results and excellent chip evacuation at shallow depths of cut. 100% Made in Japan, it is the industrial standard for CNC turning where surface integrity and dimensional precision are non-negotiable.
NS9530 Mirror Technology
This non-coated cermet grade features low affinity to steel, virtually eliminating built-up edge (BUE) and ensuring the workpiece remains bright and scratch-free.
-C Precision Breaker
The -C geometry is fine-tuned for light finishing. It provides tight chip control even at low feed rates, preventing damage to the finished surface profile.
Right-Hand Orientation
Designed specifically for right-hand tool holders (WTJNR / MTJNR), allowing for optimal chip flow away from the workpiece during external turning.

"Very stable dimensions over long batches. Cermet NS9530 is my favorite for aesthetic parts."
⭐⭐⭐⭐⭐ "Fast Delivery" - Marco D., Italy
"Beyond OYYU team provided original boxes and technical setup advice. Surface finish improved instantly."
⭐⭐⭐⭐⭐ "Authentic Partner" - Arjun P., India
"Genuine Japan stock. Significant reduction in cost per piece since we get more parts per edge on our finishing line."
8. FAQ - Precision Turning Support
Q: Why choose cermet instead of carbide for steel finishing?
A: Cermet has a much lower affinity for steel, which prevents built-up edge (BUE) and results in a significantly brighter, more accurate surface finish.
Q: Is this insert suitable for interrupted cuts?
A: Cermet is more brittle than carbide. It is highly recommended for continuous finishing. For heavy interrupted cuts, we suggest using a coated carbide grade.
Tech Tip: Optimizing Mirror Finishes
For the highest gloss with **NS9530**, maintain high cutting speeds and prioritize stable machining environments. This grade is specifically built for the final pass. **Tungaloy Japan** - Excellence in precision surface engineering.
