Tungaloy TNMG160402-11 NS9530 Turning Insert
Ultra-Precision Finishing | NS9530 Cermet Grade | 0.2mm Corner Radius
What is the best cermet insert for high-gloss steel finishing?
The Tungaloy TNMG160402-11 NS9530 is a specialized precision turning insert designed for light finishing operations on carbon and alloy steels. Utilizing the NS9530 premium cermet grade, this insert provides exceptional chemical stability and resistance to oxidation at high cutting temperatures. The 0.2mm corner radius (02) combined with the -11 chipbreaker allows for extreme dimensional accuracy and a mirror-like surface finish. 100% Made in Japan, it is the industrial benchmark for high-speed finish turning.
NS9530 Cermet Grade
A titanium-based cermet that offers superior fracture toughness and surface finish. Its low affinity for steel prevents built-up edge (BUE), maintaining a clean cut.
-11 Chipbreaker
Specifically designed for finishing to light-duty cutting. It ensures excellent chip control at small depths of cut, preventing long, stringy chips from scratching the workpiece.
Ultra-Sharp 0.2mm Edge
The small 0.2mm radius reduces cutting pressure and is perfect for thin-walled parts or applications requiring sharp internal corners and fine Ra values.

Recommended Cutting Parameters
-
Cutting Speed (Vc): 150 - 380 m/min (Maintain high speed for mirror gloss)
-
Feed Rate (f): 0.05 - 0.20 mm/rev (Optimize for 0.2mm radius)
-
Depth of Cut (ap): 0.1 - 1.2 mm
*Pro-Tip: Cermet works best in dry finishing at high speeds. High Vc levels activate the titanium cermet luster effect on steel.*
4. Primary Applications
- High-speed finishing of carbon and alloy steels.
- Final passes on precision shafts and automotive valves.
- Boring small diameters where space is limited.
- Operations requiring low cutting forces to prevent part deflection.
5. Tool Compatibility
Fits standard TN** 1604 triangular pockets. Pairs perfectly with MTJNR/L or WTJNR/L holders. Recommended for S-WTJNR boring bars for internal finishing.

8. FAQ - Machine Shop Support
Q: Is a 0.2mm radius more fragile than a 0.4mm?
A: Yes, it is more delicate. It should only be used for finishing passes with light depths of cut. Avoid heavy roughing or interrupted cuts.
Q: Can I use NS9530 on stainless steel?
A: While it can be used for very light finishing on some stainless grades, it is specifically optimized for carbon and alloy steels (P group materials).
Tech Tip: Achieving Mirror Finishes
To get the best result from **NS9530**, use high cutting speeds (Vc > 250 m/min) and ensure your machine has high spindle stability. The 0.2mm radius is the secret to perfect surface luster. **Tungaloy Japan** - Excellence in surface technology.
