ISO40 face mill adaptors (also called 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 an ISO40 spindle taper. The arbor's pilot/spigot diameter locates the face mill cutter concentrically while a radial drive key transmits cutting torque, making adaptor accuracy essential for consistent facing operations, flatness, and surface finish.
