ISO50 face mill adaptors (face mill arbors) are precision tool holders manufactured to the DIN2080 standard, used to mount face mill cutters onto CNC milling machines and machining centers with a larger ISO50 spindle taper. The bigger ISO50 interface offers higher torque capacity and rigidity than ISO40, making it suited to heavier face milling cuts on larger-diameter cutters. The arbor's pilot/spigot diameter locates the cutter concentrically while a radial drive key transmits cutting torque, so adaptor accuracy is critical for flatness and surface finish.
