The present invention is a plurality rods extending from a base of a die driver inserted into a plurality of openings in a threading die used to thread or re-thread a stud. A tool is inserted into a tool-receiving recess of the die driver and the driver is rotated.

A retaining socket for receiving a thread die includes a plunge component that is moveable along the longitudinal axis of the retaining socket and at least one pin extending parallel to the longitudinal axis configured to engage the thread die.

A handheld lithium battery threading machine includes a die head, a motor assembly, a lithium battery assembly, a toothed disc assembly, a support arm body assembly, and a gearbox assembly. The lithium battery assembly is connected to the motor assembly. The motor assembly and the toothed disc assembly are respectively mounted at both ends of the gearbox assembly. The die head is mounted on the toothed disc assembly, and the support arm body assembly is mounted on the gearbox assembly and matched with the die head. The motor assembly includes a motor, a male plug, a main switch, a handle, an air inlet window, and an air outlet window, where the motor, the male plug, and the main switch are all mounted on the handle. Both the air inlet window and the air outlet window are arranged on the handle.
