TUNGALOY CCGT09T302L-W20 NS9530
High-Feed Wiper Finishing | NS9530 Premium Cermet | 80° Rhombic Precision
Product Overview
The Tungaloy CCGT09T302L-W20 NS9530 is a specialized Cermet turning insert engineered for high-efficiency finishing in steel and ductile iron. Featuring the advanced W20 Wiper geometry, this tool allows for doubled feed rates while maintaining a superior Ra surface roughness, effectively reducing cycle times in CNC machining. The NS9530 Cermet grade provides exceptional chemical stability and wear resistance, ensuring your workpiece achieves a "mirror finish" without the risk of built-up edge (BUE). Made in Japan, this indexable turning tool is the industrial choice for precision machining that demands high aesthetic quality and dimensional accuracy.

NS9530 Grade: The Ultimate Mirror Polish
The NS9530 grade is a premium titanium-based Cermet. Unlike tungsten carbide, Cermet does not chemically react with steel, which prevents workpiece material from welding to the insert tip. This results in a cleaner cut and a significantly higher surface gloss. This long-tail keywords industry favorite ensures tool life longevity during continuous high-speed finishing operations.
W20 Wiper Technology
The W20 Wiper geometry features a secondary cutting edge that "wipes" away the ridges left by the nose radius. This allows for significantly higher feed rates without losing the Ra surface roughness 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 - 0.25 mm/rev (High-Feed Wiper Range)
-
Depth of Cut (ap): 0.1 - 0.9 mm
*Pro Tip: Ensure your tool post is perfectly centered. Wiper performance is highly sensitive to center height alignment.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Twice the speed, same finish!" - Markus R., Germany
"I swapped my standard 02 inserts for these W20 wipers. I doubled my feed and the shafts still look like they were polished. Highly efficient."
⭐⭐⭐⭐⭐ "Perfect for Swiss Lathes" - Kenji S., Japan
"Tungaloy original quality. The NS9530 grade gives the best surface finish on carbon steel. Zero smearing."
⭐⭐⭐⭐ "Very Sharp and Reliable" - David T., USA
"The 09T3 size is standard, but the Wiper geometry makes it stand out. Reliable tool life even in long production runs."
⭐⭐⭐⭐⭐ "Excellent Mirror Finish" - Fabrizio G., Italy
"No more hand polishing required for our customer's parts. This Cermet insert creates a beautiful finish straight from the CNC."
⭐⭐⭐⭐⭐ "Top Grade for Finishing" - Alan B., UK
"If you are finishing steel and want it to shine, this is the one. Fast shipping and the inserts arrived in perfect condition."
Technical Q&A
Q: Can I use this for finishing 316 Stainless Steel?
A: While NS9530 can handle some stainless, a PVD carbide grade like **AH725** is usually better for the high heat and stickiness of 316. This Cermet excels in Steels and Cast Irons.
Q: What is the benefit of the 'L' in 02L?
A: It denotes a Left-hand cutting direction. Ensure your tool holder (e.g., SCLCL09) matches the insert's hand.
Q: Does the W20 wiper work in small bores?
A: Yes, as long as your boring bar is stable. However, the wiper effect is most pronounced on outer diameter turning and large internal bores.
Expert Machining Tip: Why Cermet Wiper?
The combination of **NS9530 Cermet** and **W20 Wiper** is the ultimate productivity hack. Cermet provides the chemical resistance for a mirror surface, while the Wiper allows you to run faster. It is the perfect indexable turning tool for shops looking to beat deadlines without failing quality control.
