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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
