Tungaloy TNMG160404-11 NS9530 Turning Insert
High-Speed Mirror Finishing | -11 Chipbreaker | Premium NS9530 Cermet
How do I get a mirror surface finish on steel at high cutting speeds?
The Tungaloy TNMG160404-11 NS9530 is an industry-leading cermet turning insert specifically optimized for high-speed finishing of carbon and alloy steels. Featuring the NS9530 grade, a titanium-based cermet with high fracture toughness, this insert prevents the chemical reaction between the tool and the workpiece that often causes surface dullness. The -11 chipbreaker provides excellent chip control even at shallow depths of cut, ensuring a scratch-free finish. 100% Made in Japan, it is the professional choice for high-gloss precision components.
NS9530 Cermet Grade
Maintains a sharp cutting edge much longer than coated carbide. It offers superior thermal stability, perfect for high-speed dry finishing where surface luster is critical.
-11 Precision Chipbreaker
Optimized for light-duty finishing. The geometry ensures smooth chip evacuation at low feed rates, preventing "birds-nesting" during automated CNC cycles.
High Fracture Resistance
Unlike standard cermets that are brittle, the NS9530 grade is engineered for toughness, allowing for reliable performance even in light interrupted cuts.

Recommended Cutting Parameters
-
Cutting Speed (Vc): 150 - 350 m/min (Recommended for high speed)
-
Feed Rate (f): 0.05 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro-Tip: Cermet grades like NS9530 perform best in dry cutting conditions during finishing. High spindle speeds activate the cermet surface burnishing effect.*
4. Primary Applications
- Fine finishing of low to medium carbon steels.
- Final dimensioning of precision shafts and axles.
- Automotive components requiring mirror-like surface luster.
- Boring operations where Ra values under 0.8 are required.
5. Equipment Compatibility
Fits all standard TN** 1604 triangular pockets. Fully compatible with MTJNR/L, WTJNR/L, and DTGNR/L tool holders. Recommended for CNC lathes and multitasking centers.

8. FAQ - Machine Shop Technicals
Q: Can I use this for roughing?
A: No. NS9530 is a cermet grade designed for finishing. For roughing, we recommend T9200 series coated carbide grades.
Q: Does this require coolant?
A: Cermet actually performs exceptionally well in dry cutting environments, which helps avoid thermal shocking of the edge.
Tech Tip: Cermet vs Carbide
While carbide is tougher, **Cermet (NS9530)** has lower affinity for steel, making it the best choice for achieving high surface gloss and maintaining dimensional stability in finishing passes. **Tungaloy Japan** - Excellence in surface technology.
