VP15TF Miracle PVD Coating
The VP15TF grade utilizes Mitsubishi's proprietary Miracle PVD coating. This nano-layered coating provides an incredible balance of hardness and heat resistance. Unlike CVD coatings, PVD is thinner and keeps the cutting edge sharper, making it exceptionally effective at preventing built-up edge (BUE) on stainless steel and delivering long tool life across varied material groups.
MA Precision Chipbreaker
The MA chipbreaker is a double-sided geometry optimized for medium cutting. It features a specific land angle that reduces cutting forces, which is critical when machining smaller diameters or thin-walled workpieces. The MA geometry ensures stable chip control even at varied depths of cut, providing smooth CNC turning results.

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.
