RPMT1204MOE-JS F7030
Mitsubishi Materials | The Cast Iron & General Purpose Specialist
The Mitsubishi RPMT1204MOE-JS F7030 is a specialized 12mm round milling insert engineered for high-stability copy milling and face milling. Utilizing the rugged F7030 PVD coating, this insert is primarily optimized for machining cast iron and carbon steels. The circular geometry combined with the JS chipbreaker provides a high-strength cutting edge that excels in heavy-duty CNC milling, offering superior wear resistance against the abrasive nature of nodular and grey iron.

F7030 Coating Performance
The F7030 grade is a specialized PVD coating designed for thermal shock resistance. It is exceptionally effective in milling applications where coolants create rapid temperature fluctuations. While it performs well in general steel, its true strength lies in its ability to resist the abrasive wear typical of Cast Iron (K-class) machining, extending tool life in high-volume production.
JS Low-Load Geometry
The JS chipbreaker features a 3D sharp-edge design. In indexable milling, the round R-shape can generate high radial pressure; the JS design offsets this by reducing cutting resistance. This ensures smooth chip evacuation and prevents vibration, allowing for high-quality surface finishes even when profiling deep cavities.

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.
