Tungaloy TNGG160404L-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 TNGG160404L-W NS9530 represents the pinnacle of finishing technology. Featuring the revolutionary -W Wiper geometry, this left-hand cermet insert allows CNC operators to double their feed rates without compromising surface roughness. Built with the NS9530 premium cermet grade, it provides unmatched chemical stability when machining carbon and alloy steels, effectively eliminating built-up edge (BUE). 100% Made in Japan, this tool is engineered for high-productivity workshops that demand both speed and a high-gloss finish.
Wiper Technology (-W)
The specially 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.
G-Class Precision
Fully ground periphery ensures high mounting accuracy. Expect minimal deviation between insert changes, perfect for tight tolerance B2B production.

Optimized Cutting Parameters
-
Cutting Speed (Vc): 150 - 350 m/min (Maintain high speed for mirror finish)
-
Feed Rate (f): 0.10 - 0.35 mm/rev (Take advantage of the Wiper edge!)
-
Depth of Cut (ap): 0.2 - 1.5 mm
*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.
- Boring and turning where Ra values are critical.
- Automotive components requiring rapid cycle times.
- Mass production environments requiring ground-quality finishes.
5. Tool Compatibility
Standard fit for TN** 1604 pockets. Pairs with WTJNL or MTJNL Left-hand external holders and S-WTJNL internal boring bars.

Machinist Feedback on NS9530 Wiper
⭐⭐⭐⭐⭐ "Cycle Time Reduced by 40%" - Robert V., USA
"The Wiper edge is a game changer. I'm running these at twice the feed rate of my old inserts and the surface is even better. NS9530 grade is super stable."
⭐⭐⭐⭐⭐ "Original Japan Quality" - K. Schmidt, Germany
"Exactly what we needed for our alloy steel shafts. Mirror finish every time. Beyond team was very helpful with technical specs."
⭐⭐⭐⭐ "Great for Mass Production" - Hiroshi L., Japan
"Consistent wear over long runs. The -W breaker handles the chips perfectly even at high feed. Very reliable."
⭐⭐⭐⭐⭐ "Beautiful Luster" - Marco D., Italy
"Surface finish is like jewelry. Using these on steel bushings. Authentic Tungaloy and fast shipping."
⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Amit J., India
"Genuine inserts, well packed. The NS9530 cermet is very tough for finishing. Highly recommended."
8. FAQ - Professional Support
Q: Can I use the Wiper insert on a tapered surface?
A: Yes, but keep in mind that the wiper effect is most pronounced on straight diameters. On steep tapers, the finish might differ slightly from a standard radius.
Q: Is this insert compatible with standard TNMG holders?
A: Absolutely. It uses the standard 16mm triangular pocket, but being a left-hand (L) insert, it must be used in a left-hand (L) tool holder.
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.
