RPMT1606MOE-JS VP15TF
Mitsubishi Materials | Heavy-Duty Round Insert for Large Scale Profiling
The Mitsubishi RPMT1606MOE-JS VP15TF is a heavy-duty 16mm round milling insert engineered for high-volume copy milling and large-scale profiling. Featuring the legendary VP15TF Miracle PVD coating, this insert is designed to handle high thermal loads while maintaining edge sharpness. The specialized JS chipbreaker geometry effectively reduces cutting resistance, making it the premier choice for CNC milling of mold bases, large steel structures, and aerospace components.

VP15TF Technology
The VP15TF grade utilizes Mitsubishi's proprietary Miracle PVD coating. This ultra-fine Al-Ti-N layer provides a powerful barrier against heat and wear resistance. It is the gold standard for machining stainless steel and alloy steels, offering incredible toughness to withstand interrupted cuts in heavy roughing applications.
JS Precision Geometry
The JS chipbreaker is a 3D-molded geometry designed to break chips effectively even at varying lead angles. In indexable milling, the round shape (R) creates high radial forces; the JS design compensates by sharpening the effective rake, significantly lowering cutting resistance and preventing work hardening in sensitive materials.

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.
