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.

Power drive tools are described. The tools include one or more threading pawls, one or more release pawls, and a drive ring selectively positionable relative to the tool and engaged with the pawls to selectively extend or retract the pawls. Also described are tools that include one or more lights to illuminate a workpiece. Also described are tools having distally located shoulder regions at which force may readily be applied. In addition, gear train assemblies for use in the power drive tools are described.
