VP15TF Miracle Coating
The VP15TF Miracle Grade is Mitsubishi’s proprietary PVD coating designed for versatility. It provides superior wear resistance and oxidation resistance, making it ideal for stainless steel turning. Its high adherence to the carbide substrate effectively prevents built-up edge (BUE), which is critical for maintaining high dimensional accuracy on CNC lathes.
FM Chipbreaker Geometry
The FM Chipbreaker (Finishing-Medium) is the primary choice for light-to-medium finishing. It features a sharp cutting edge that minimizes cutting resistance, preventing workpiece deformation. With a 0.8mm radius, it provides a very strong edge that can handle higher feed rates while still ensuring chips are curled tightly for easy removal.

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.
