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.

A powered threading machine is described. The threading machine is compact and portable. The threading machine includes a tube frame having a rearward wheel assembly and an extendable handle at the front of the machine. A particular sump configuration is used to prevent loss of cutting oil during operation and transport of the machine.
