Tungaloy TNGG160404R-W NS9530 Turning Insert
High-Speed Steel Finishing | -W Wiper Edge | Premium NS9530 Cermet
What is the best way to double feed rates while maintaining a mirror finish?
The Tungaloy TNGG160404R-W NS9530 is a high-performance right-hand cermet insert specifically engineered for high-efficiency finishing of carbon and alloy steels. Featuring Tungaloy's innovative -W Wiper technology, this insert allows CNC operators to significantly increase feed rates—often doubling them—while achieving a surface roughness equivalent to or better than standard radius inserts. Built with the NS9530 premium cermet grade, it offers exceptional chemical stability and resistance to built-up edge (BUE). 100% Made in Japan, it is the industrial choice for high-gloss, high-productivity steel turning.
-W Wiper Geometry
The wiper edge "smooths" the workpiece surface as it passes. This unique geometry allows for high feed rates without the "thread-like" surface marks typical of standard inserts.
NS9530 Cermet Grade
A titanium-based cermet with superior fracture toughness. It maintains a sharp cutting edge and provides excellent surface luster at high cutting speeds.
Precision Ground Edge
Ground to G-class tolerances, this insert ensures high repeatability and minimal tool offset adjustment between indexings in automated production.

Recommended Cutting Parameters
-
Cutting Speed (Vc): 150 - 350 m/min (Maintain speed for best gloss)
-
Feed Rate (f): 0.10 - 0.35 mm/rev (Wiper advantage zone)
-
Depth of Cut (ap): 0.2 - 1.5 mm
*B2B Pro Tip: When using the Wiper (-W) geometry, you can often double your feed rate and still achieve a better finish than a standard radius at half the speed.*
4. Primary Applications
- High-efficiency finish turning of carbon and alloy steels.
- Final passes on CNC lathes requiring ground-quality Ra values.
- Automotive components with tight cycle-time requirements.
- Shafts, rollers, and bearing surfaces.
5. Tool Compatibility
Pairs perfectly with standard TN** 1604 pockets. Fits WTJNR or MTJNR Right-hand external tool holders. Also optimized for S-WTJNR internal boring bars.

8. FAQ - Technical Support
Q: Do I need a special tool holder for a Wiper insert?
A: No. It fits standard TNMG pockets. However, the tool holder must be aligned correctly to the workpiece for the wiper effect to be effective.
Q: Is NS9530 better than carbide for mirror finishing?
A: Yes. Cermet (NS9530) has a much lower chemical affinity for steel, which prevents built-up edge and produces a higher gloss finish than carbide.
Tech Tip: Cermet Wiper Handling
Cermet is more brittle than carbide. For best results with **NS9530**, avoid heavy intermittent cuts and ensure the workpiece is held securely. The **Wiper edge** works best at high RPMs. **Tungaloy Japan** - Excellence in surface technology.
