Premium T9115 CVD Grade
The T9115 grade is a flagship CVD coating designed for superior efficiency in steel turning. By incorporating a thick Al2O3 layer and a specialized binder, it manages heat better than standard carbide. This long-tail keywords industry favorite allows for higher cutting speeds without compromising the structural integrity of the tool edge, making it perfect for precision machining in high-volume production.
24 Chipbreaker Geometry
The 24-style chipbreaker is Tungaloy's answer to difficult chip control during light-to-medium finishing. Its unique geometry breaks chips early, preventing them from wrapping around the workpiece or the boring bar, which is vital for maintaining high surface quality.
Recommended Cutting Parameters
Optimized for P (Steel) Turning:
-
Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
-
Feed Rate (f): 0.05 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 2.0 mm
*Note: CVD grades perform exceptionally well in high-heat environments where speed is prioritized.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Reliable Production" - Markus R., Germany
"T9115 is incredibly stable. We ran 500 alloy steel parts and the insert showed very little wear. Highly recommended for CNC production."

⭐⭐⭐⭐ "Great for High Speed" - David L., USA
"Pushed the RPM on our lathe and the CCMT09T304 held up perfectly. T9115 loves the heat."
⭐⭐⭐⭐⭐ "Perfect Finish" - Antonio V., Italy
"Excellent surface finish for steel parts. The 0.4mm radius is perfect for fine detail and finishing passes."
⭐⭐⭐⭐⭐ "Fast Delivery & Original" - Lee W., UK
"Original Japanese inserts. Fast shipping. Performance is exactly what you'd expect from Tungaloy."
Technical Q&A
Q: Can I use this for machining 304 Stainless Steel?
A: While it can cut some stainless, T9115 is optimized for Steel (P). For dedicated Stainless Steel work, Tungaloy’s T6120 or AH725 series is recommended.
Q: What is the benefit of CVD coating over PVD?
A: CVD coatings are thicker and provide better heat protection, making them superior for continuous, high-speed turning in steel.
Q: Which tool holder fits this insert?
A: It fits any standard **SCLCR09** or **SCLCR3/8** external turning tool or boring bar designed for size 09T3 inserts.
Machining Tip: CVD vs. Cermet
For light finishing requiring a mirror finish, consider Cermet (NS9530). However, for production stability, high-speed roughing, and semi-finishing in steel, the T9115 CVD grade is the superior choice for consistent tool life.
