Tungaloy CCMT09T308-24 T9115 Turning Insert
Durable CVD Coated Carbide | High-Speed Steel Turning | 0.8mm Radius
Product Overview
The Tungaloy CCMT09T308-24 T9115 is a high-productivity CVD coated carbide turning insert engineered for high-speed continuous and light interrupted turning of steel. Featuring the industrial-standard T9115 grade, this insert offers exceptional resistance to heat and wear, making it a favorite for long production runs. The 0.8mm corner radius provides increased edge strength and allows for higher feed rates compared to smaller radii. Integrated with the 24-style chipbreaker, it ensures reliable chip evacuation in CNC machining. Made in Japan, this indexable turning tool is the professional solution for maintaining consistent tool life and accuracy in precision machining.

T9115 CVD Coating Performance
The T9115 grade is Tungaloy's premier CVD coating for steel turning. It features a multi-layered design with a thick Al2O3 layer that provides exceptional heat insulation. This long-tail keywords industry favorite protects the carbide substrate from the high temperatures generated during high-speed CNC machining. It significantly reduces plastic deformation and crater wear, ensuring consistent tool life in automated production environments.
Reliable 24 Chipbreaker
The 24 Chipbreaker is optimized for finishing to light-medium turning. Its geometry is designed to maintain effective chip control even as feed rates increase, preventing the "bird-nesting" of chips that can damage surface finishes and tool holders.
Recommended Cutting Parameters
Optimized for P (Steel) Applications:
-
Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
-
Feed Rate (f): 0.08 - 0.25 mm/rev
-
Depth of Cut (ap): 0.5 - 2.5 mm
*Pro Tip: Use the higher range of cutting speeds to take full advantage of the T9115 heat-resistant coating.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Excellent production tool" - Matthias B., Germany
"T9115 is extremely predictable. We use these for 24/7 production on alloy steel and the tool life is outstanding."
⭐⭐⭐⭐⭐ "Consistent Quality" - Hiroshi S., Japan
"Authentic Tungaloy inserts. The 0.8mm radius is very strong. Great for both semi-finishing and finishing steel parts."
⭐⭐⭐⭐ "Great Heat Resistance" - John K., USA
"Ran these at high speeds and they held up perfectly. T9115 really shines when the chips are flying hot."
⭐⭐⭐⭐⭐ "Reliable Chip Control" - Paolo M., Italy
"The 24 chipbreaker is very effective. No more long stringy chips scratching the part surface."
⭐⭐⭐⭐⭐ "Original & Fast Shipping" - David R., Australia
"Genuine Japanese product. Perfect fit for our SCLCR boring bars. Highly recommend."
Technical Q&A
Q: Can I use this for machining Cast Iron?
A: While it can cut cast iron, T9115 is optimized for Steel (P). For Cast Iron (K), Tungaloy’s T5115 series is specifically designed for better performance.
Q: What is the advantage of the 0.8mm radius over 0.4mm?
A: The 0.8mm (08) radius is stronger and allows for higher feed rates, making it more durable for semi-finishing or light interrupted cuts.
Q: Which tool holder fits this insert?
A: It fits any standard **SCLCR09** or **SCLCR3/8** turning tool holder 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 turning, and semi-finishing in steel, the T9115 CVD grade is the superior choice for consistent results in precision machining.
