1. A portable pipe threader comprising:
a housing;
a carriage supported by the housing;
at least one pipe threading tool coupled to the carriage and selectively operable to perform work on a pipe;
a drive assembly at least partially positioned within the housing, the drive assembly including an electric motor operable to provide torque to rotate the pipe; and
a lubrication system including:
a catch basin provided on one side of the housing,
a reservoir for holding a lubricant,
a debris shield positioned to shield the reservoir from debris formed during the work on the pipe,
a drip catch having one or more pockets that open toward the debris shield, and
a pump powered by the drive assembly to establish a flow of lubricant from the reservoir; and
a stand adjustable between a collapsed state and a deployed state,
wherein, with the stand in the collapsed state, the portable pipe threader can be put in a vertically stowed configuration in which a longitudinal axis of the housing is substantially vertical with respect to a floor or ground surface, and
wherein, in the vertically stowed configuration, the debris shield is oriented substantially vertically above the drip catch so that the one or more pockets of the drip catch can catch and retain lubricant dripped from a proximal edge of the debris shield.
