SCMT09T304 VP15TF
Mitsubishi Materials | The Miracle Coated Versatility Specialist
The Mitsubishi SCMT09T304 VP15TF is a premium carbide turning insert engineered for high-reliability CNC machining. Utilizing the legendary VP15TF Miracle PVD coating, this insert is the ultimate all-rounder, excelling in machining stainless steel, carbon steels, and heat-resistant alloys. Its 7° positive relief angle (S-Type) ensures low cutting resistance, making it a perfect match for both external turning and high-precision internal boring operations.

VP15TF Miracle Grade
The VP15TF grade features Mitsubishi’s unique (Al,Ti)N PVD coating. This coating offers exceptional wear resistance and thermal stability. Its micro-grain carbide substrate provides high toughness, preventing edge chipping even during interrupted cuts or when machining gummy materials like 300-series stainless steel.
Finishing Geometry
The indexable turning geometry of the SCMT is optimized for precision machining. The 0.4mm (1/64") radius is ideal for achieving fine surface finishes and maintaining dimensional tolerances. The positive rake angle chipbreaker effectively manages chip control, reducing heat buildup in the cutting zone.

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.
