Tungaloy DCMT070204-PS T9115 Turning Insert
High-Speed Steel Finishing Specialist | Premium T9115 CVD | Made in Japan
How do I improve tool life during high-speed steel turning?
The Tungaloy DCMT070204-PS T9115 is a high-performance CVD coated carbide turning insert engineered specifically for high-speed finishing of steel. Utilizing the advanced T9115 grade, this insert features Tungaloy's "PremiumTec" surface technology, which provides exceptional resistance to crater wear and plastic deformation at high temperatures. The -PS chipbreaker (Polish Style) is designed with a sharp cutting edge and optimized rake to ensure stable chip evacuation even at low depths of cut. This Japan-made indexable turning tool with a 0.4mm corner radius is the professional CNC machining choice for shops targeting shorter cycle times and consistent tool life. Integrating this long-tail keywords optimized insert into your production allows for higher cutting speeds (Vc) while maintaining a premium surface finish on carbon and alloy steels.

Why choose T9115 CVD coating for steel finishing?
The T9115 Grade is a multi-layered CVD coated carbide designed for high-speed stability. It features a special Al2O3 layer that provides an exceptional heat barrier, allowing for higher cutting speeds without losing edge integrity. In precision machining, the -PS chipbreaker acts to reduce cutting resistance and vibration. For CNC machining shops, this indexable turning tool provides the perfect balance between high efficiency and fine surface quality. This is a must-have for high-volume steel finishing where cycle time reduction is the primary goal.
Recommended Cutting Parameters (T9115)
-
Cutting Speed (Vc): 150 - 350 m/min (Standard Steels)
-
Feed Rate (f): 0.05 - 0.20 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro Tip: CVD coatings like T9115 perform best at high temperatures. Don't be afraid to increase your Vc for better chip breaking and tool life.*
Feedback from Global Machinists
⭐⭐⭐⭐⭐ "Cycle Time Saver" - Mark T., USA
"Switched to T9115 for our 1045 steel pins. We increased speed by 20% and tool life actually improved. The -PS breaker keeps chips short."
⭐⭐⭐⭐⭐ "Stable and Sharp" - H. Fischer, Germany
"Very consistent performance in high-speed finishing. The 0.4mm radius is perfect for fine detail work. Genuine Japan quality."
⭐⭐⭐⭐ "Great for Mass Production" - Kenji O., Japan
"We run thousands of parts on our CNC. The dimensional stability with these Tungaloy inserts is the best we've tested."
⭐⭐⭐⭐⭐ "Beautiful Finish" - Luca P., Italy
"Zero built-up edge even after long runs. The CVD coating handles the heat very well. Excellent value for money."
⭐⭐⭐⭐⭐ "Reliable Delivery" - Sarah M., UK
"Original inserts, fast shipping. They work perfectly on our alloy steel components. Highly recommended for any CNC workshop."
Technical Tooling Q&A
Q: Can I use T9115 for stainless steel?
A: T9115 is optimized for steel. For stainless steel, we recommend PVD grades like AH725 for better resistance to work hardening and built-up edge.
Q: Is CVD better than PVD for finishing?
A: CVD (like T9115) is superior for high-speed, continuous cuts in steel because it handles heat better. PVD is better for toughness and interrupted cuts.
Q: What tool holder fits this DCMT 0702?
A: This fits all standard ISO holders like SDJCR/L 1010/1212 or internal boring bars like S...-SDUCR07.
Expert Tip: Maximizing CVD Performance
In precision machining, CVD Coated Carbide (T9115) reaches its peak efficiency when the cutting edge is hot. Ensure your Vc is high enough to allow the Al2O3 layer to protect the substrate, ensuring long tool life and a brilliant finish.
