Tungaloy TNGG160408R-W NS9530 Wiper Insert
High-Speed Finishing | -W Wiper Geometry | NS9530 Premium Cermet
How can I double my feed rate while maintaining a mirror surface finish?
The Tungaloy TNGG160408R-W NS9530 is a high-performance right-hand cermet insert engineered for maximum productivity in steel finishing. Featuring Tungaloy's world-renowned -W Wiper technology, this insert allows CNC operators to double their feed rates without sacrificing surface quality. Built with the NS9530 premium cermet grade, it offers unmatched chemical stability, effectively preventing built-up edge (BUE) and providing a high-gloss luster on carbon and alloy steels. 100% Made in Japan, it is the professional's choice for reducing cycle times in precision turning.
Wiper Geometry (-W)
The curved wiper edge "smooths" the material as it cuts. This allows for significantly higher feed rates compared to standard radius inserts while achieving superior Ra values.
NS9530 Cermet Grade
A titanium-based cermet that excels in high-speed finishing. It offers high fracture toughness and resistance to oxidation, keeping the cutting edge sharp for longer cycles.
0.8mm Strong Radius
The 0.8mm radius provides increased edge strength for stable finishing, allowing for deeper cuts and more aggressive parameters than a 0.4mm radius.

Recommended Cutting Parameters
-
Cutting Speed (Vc): 150 - 350 m/min (Maintain high speed for mirror gloss)
-
Feed Rate (f): 0.15 - 0.45 mm/rev (Wiper efficiency zone)
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro-Tip: When using the Wiper (-W) geometry, push the feed rate. Higher feeds often result in better surface finishes due to the burnishing effect of the wiper edge.*
4. Primary Applications
- High-efficiency finish turning of carbon and alloy steels.
- Final dimensioning for automotive components and shafts.
- Boring operations requiring Ra values under 0.8μm.
- Achieving mirror-like luster on high-precision bearing surfaces.
5. Tool Compatibility
Standard fit for TN** 1604 pockets. Pairs perfectly with WTJNR or MTJNR Right-hand external holders and S-WTJNR internal boring bars.

"Original Japan stock. Using these on our CNC lathes for high-gloss steel shafts. Dimensional stability is excellent batch after batch."
⭐⭐⭐⭐ "Great Chip Control" - David L., USA
"Handles higher feed rates easily without scratching the surface. The NS9530 cermet stays sharp even after long runs."
⭐⭐⭐⭐⭐ "Mirror Finish on Alloy Steel" - Alessandro B., Italy
"Beyond provided authentic factory-sealed boxes and the technical data was very helpful for our machine setup."
⭐⭐⭐⭐⭐ "Fast Shipping and Original" - Ahmed K., UAE
"Verified original Tungaloy inserts. Best source for our workshop's high-precision finishing needs."
8. FAQ - Professional Technical Support
Q: Why should I choose the 0.8mm radius over the 0.4mm?
A: The 0.8mm radius (08) offers higher edge strength and stability. When combined with the wiper geometry, it allows for significantly higher feed rates while maintaining a superior finish.
Q: Is NS9530 suitable for dry cutting?
A: Yes. Cermet excels in dry finishing because it has high thermal stability and does not chemically react with steel, preventing the built-up edge common with carbide.
Tech Tip: Cermet vs Carbide for Wiper Finishing
While carbide is tougher, **Cermet (NS9530)** maintains sharp wiper edges longer because it won't chemically bond with the steel. Combined with **Wiper Geometry**, it's the fastest way to get a mirror finish. **Tungaloy Japan** - Excellence in surface technology.
