TUNGALOY CCGT09T304L-W20 NS9530
High-Feed Wiper Finishing | NS9530 Premium Cermet | 80° Rhombic Precision
Product Overview
The Tungaloy CCGT09T304L-W20 NS9530 is a high-efficiency Cermet turning insert engineered for ultra-fine finishing operations. Featuring the revolutionary W20 Wiper geometry, this tool allows for doubled feed rates while achieving a superior Ra surface roughness, effectively slashing cycle times in CNC machining. The NS9530 Cermet grade provides exceptional chemical stability and resistance to built-up edge (BUE), ensuring your workpiece maintains a "mirror finish" throughout the batch. Made in Japan, this indexable turning tool is the industrial standard for precision machining of steel and ductile iron.

NS9530 Cermet Grade: Superior Chemical Stability
The NS9530 grade is a titanium-based Cermet known for its extreme hardness and chemical inertness. Unlike carbide, it won't react with the steel being cut, preventing "smearing" and built-up edge. This long-tail keywords favorite allows for high-speed machining while maintaining a razor-sharp edge for the entire tool life.
W20 Wiper Geometry Explained
The W20 Wiper edge features a modified radius that "wipes" away the ridges created by standard nose radii. This allows the CCGT09T304L-W20 to perform high-feed finishing (up to 2x faster) without losing the Ra surface roughness quality required for precision machining.
Recommended Cutting Parameters
Optimized for P (Steel) and K (Cast Iron) Finishing:
-
Cutting Speed (Vc): 130 - 280 m/min (425 - 920 SFM)
-
Feed Rate (f): 0.05 - 0.30 mm/rev (Wiper advantage range)
-
Depth of Cut (ap): 0.1 - 1.0 mm
*Pro Tip: For the best results with wiper inserts, ensure the lathe tool post is rigid and the center height is precisely aligned.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Incredible Feed Rates" - Matthias K., Germany
"Switched to the W20 wiper and doubled my feed rate. Cycle time dropped significantly and the finish is still like a mirror."
⭐⭐⭐⭐⭐ "Beautiful Surface Finish" - Hiroshi T., Japan
"NS9530 is my go-to for steel finishing. No stickiness, very bright surfaces. Genuine Tungaloy quality."
⭐⭐⭐⭐ "Great for CNC Mass Production" - Robert L., USA
"Consistent results throughout the whole pack. The left-hand geometry works perfect for our setup. High efficiency."
⭐⭐⭐⭐⭐ "Top Quality Tungaloy" - Fabrizio G., Italy
"Used these for high-precision components. The W20 wiper leaves a ground-like finish. Very satisfied."
⭐⭐⭐⭐⭐ "Fast Delivery & Authentic" - Alan D., UK
"Precisely as described. Japanese-made excellence. These cermet inserts are unbeatable for finishing steel."
Technical Q&A
Q: Can I use this for machining 304 Stainless Steel?
A: NS9530 is a Cermet optimized for Steels. For Stainless, a PVD carbide like AH725 is usually better for preventing notch wear.
Q: What tool holder fits this insert?
A: It fits any standard **SCLCL09** or **SCLCL3/8** turning tool or boring bar designed for 09T3 size inserts.
Q: Does the 'L' in 04L matter?
A: Yes. It denotes a Left-hand cutting direction. Pair this with a Left-hand (SCLCL) holder.
Expert Machining Tip: Why Cermet Wiper?
For precision machining, the chemical stability of **NS9530 Cermet** prevents material "smearing," while the **W20 Wiper** allows for high-speed throughput. This combination is the ultimate choice for shops that need a mirror finish and fast cycle times in CNC machining.
