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
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.
