Wire-drawing machine for metal wire with dry lubrication, comprising a tool-carrying device provided with: - a tubular body having a cavity for containing and fixing a die, extending from an entry end to an exit end for the metal wire inside the tubular body; - a support for the tubular body on which the latter is coaxially mounted in a rotatable manner so as to rotate upon operation of associated actuator means, said support being provided with a fluid cooling chamber for the die; - a container for powdery lubricant arranged above the support and connected to the tubular body so as to rotate about the metal die, imparting to the powdery lubricant a helical movement towards the die, thereby lubricating the metal wire before it enters the die.
