Tungaloy SCMT09T304-PS T9115 Insert
High-Speed Steel Machining | -PS Precision Breaker | T9115 CVD Grade
What is the best carbide insert for high-speed finishing of steel?
The Tungaloy SCMT09T304-PS T9115 is a high-performance square carbide turning insert specifically engineered for the high-speed processing of ISO P (Steel) materials. Featuring the advanced T9115 CVD coating, this grade offers unparalleled wear resistance and plastic deformation resistance at high temperatures. The -PS chipbreaker provides a positive rake angle designed for finishing to light-medium cutting, ensuring exceptional surface quality and efficient chip evacuation. Made in Japan, this insert is the industry's go-to for maximizing productivity in CNC turning centers.
Advanced T9115 Grade
A dedicated CVD grade with high aluminum content in the Al2O3 layer, providing extreme heat resistance for high-speed (Vc) operations.
-PS Finishing Breaker
Optimized for finishing. The sharp edge and positive geometry prevent built-up edge and lower the cutting force on small lathes.
PremiumTec Surface
Tungaloy's special coating post-treatment smooths the surface to significantly reduce friction and chip welding during steel turning.

8. FAQ - Professional Support
Q: Is T9115 better than T9125?
A: T9115 is optimized for higher cutting speeds and continuous finish cuts. T9125 is a better all-rounder for general medium cutting with light interruptions.
Q: Can I use this for stainless steel?
A: T9115 is specifically for ISO P (Steel). For stainless steel (ISO M), we recommend the AH series or T6100 series grades.
Q: Will this fit my standard SSDCN holder?
A: Yes, it is a standard ISO SCMT 09T3 size and is perfectly compatible with SSDCN series holders.
Expert Tip: Why T9115 for High-Speed Turning?
The T9115 CVD grade is designed to withstand the crater wear that occurs at extreme cutting speeds. If your machine can handle the RPM, switching to T9115 allows you to drop your cycle times significantly without sacrificing tool life. For finishing alloy steels, the SCMT09T304-PS is the ultimate efficiency tool.
