RPMT1204MOE-JS VP15TF
Mitsubishi Materials | Industrial Grade Round Insert for 3D Profiling
The Mitsubishi RPMT1204MOE-JS VP15TF is a robust 12mm round milling insert engineered for high-versatility copy milling and profiling. By leveraging the industry-proven Miracle VP15TF PVD coating, this insert provides exceptional thermal stability and wear resistance across steel, stainless steel, and difficult-to-cut materials. The precision-ground JS chipbreaker is specifically designed to minimize cutting resistance, making it the premier choice for CNC milling centers focusing on mold and die or aerospace components.

VP15TF Miracle Grade
The VP15TF grade is a flagship PVD coated carbide from Mitsubishi Materials. It features a unique (Al,Ti)N coating that offers high oxidation resistance and superior bonding to the carbide substrate. This allows for reliable machining of stainless steel and carbon steel even in interrupted cuts, significantly extending tool life compared to conventional PVD grades.
JS Profiling Chipbreaker
The JS chipbreaker is a 3D sharp-edged geometry optimized for indexable milling. By creating a lower cutting resistance, the JS design prevents vibration (chatter) and reduces heat generation at the cutting edge. This is critical for 3D profiling where the depth of cut varies, ensuring a consistent surface finish and dimensional accuracy.

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.
