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.
