SCMT09T308-FM VP15TF
Mitsubishi Materials | Miracle Grade Precision Finishing Specialist
The Mitsubishi SCMT09T308-FM VP15TF is a high-performance indexable turning insert designed for semi-finishing to finishing operations. Featuring the world-class VP15TF Miracle Grade PVD coating, it provides an exceptional balance of wear resistance and toughness. The FM chipbreaker is specifically engineered to handle low depths of cut, providing excellent chip evacuation and a mirror surface finish on steel, stainless steel, and heat-resistant alloys in high-precision CNC machining applications.

VP15TF Miracle Coating
The VP15TF Miracle Grade is Mitsubishi’s proprietary PVD coating designed for versatility. It provides superior wear resistance and oxidation resistance, making it ideal for stainless steel turning. Its high adherence to the carbide substrate effectively prevents built-up edge (BUE), which is critical for maintaining high dimensional accuracy on CNC lathes.
FM Chipbreaker Geometry
The FM Chipbreaker (Finishing-Medium) is the primary choice for light-to-medium finishing. It features a sharp cutting edge that minimizes cutting resistance, preventing workpiece deformation. With a 0.8mm radius, it provides a very strong edge that can handle higher feed rates while still ensuring chips are curled tightly for easy removal.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
