Abstract: A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand, and a plurality of pipe threading tools coupled to the carriage and selectively operable to perform work on the pipe. The portable pipe threader further includes a drive assembly mounted to the stand including a brushless direct current (“DC”) motor operable to provide torque to one of the pipe or a selected one of the pipe threading tools to rotate the pipe and the selected one of the pipe threading tools relative to each other, and a battery pack supported by the stand in selective electrical communication with the motor to provide electrical power to the motor.

Abstract: A circular saw plunge pipe cutter includes a main housing, a drive mechanism at least partially disposed within the main housing, a saw blade operably coupled with the drive mechanism, and a shoe slidably coupled to the main housing. The shoe includes a pipe receptacle in which a pipe is receivable. The circular saw plunge pipe cutter is adjustable between a plunge state, in which the main housing moves toward the shoe and the saw blade extends into the pipe receptacle, and a retracted state in which the main housing moves away from the shoe and the saw blade does not extend into the pipe receptacle.

Abstract: A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand upon which at least one pipe threading tool is supported, a spindle including a plurality of chuck jaws for clamping the pipe, the chuck jaws configured to move radially inward along a travel path toward an outer surface of the pipe, and a sensor system configured to determine a location of the chuck jaws along the travel path and relative to the outer surface of the pipe, the sensor system configured to output a signal corresponding to the location of each of the chuck jaws when engaged with the outer surface of the pipe. The portable pipe threader further includes an electronic controller in communication with the sensor system configured to determine an outer diameter of the pipe in response to the signal output from the sensor system.

Abstract: A cable stripping tool removes a cable jacket from a cable to expose a plurality of neutral wires, the cable stripping tool including a housing, a frame coupled to the housing, a mandrel extending from the housing and rotatable about a first axis, and a motor supported by the housing and operably coupled to the mandrel to rotate the mandrel about the first axis. The frame supports the cable stripping tool on the cable and the mandrel engages a starter wire of the plurality of neutral wires. Rotation of the mandrel by the motor winds the starter wire around the mandrel such that the cable jacket is torn by the starter wire. The cable stripping tool further includes a termination tool configured to score the cable jacket at a desired distance from an end of the cable.

Abstract: A portable pipe threader includes a housing, a carriage, and at least one pipe threading tool. A drive assembly of the is at least partially positioned within the housing and includes an electric motor operable to provide torque to the pipe. A lubrication system is removably coupled to the housing and includes a reservoir for holding a lubricant and a pump powered by the drive assembly. A stand of the portable pipe threader is adjustable between collapsed and deployed states. When collapsed, a longitudinal axis of the housing is maintained at a first oblique angle relative to a horizontal reference plane parallel with a work surface upon which the stand is supported to funnel lubricant toward the reservoir. When deployed, the longitudinal axis is maintained at a second oblique angle to funnel lubricant away from an end of the pipe on which a working operation is performed.

Abstract: A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand, a spindle mounted to the carriage for clamping the pipe against rotation such that the pipe is stationary, a plurality of pipe threading tools coupled to the carriage and selectively operable to perform work on the pipe, a drive assembly including a plurality of brushless direct current (BLDC) motors. Each of the plurality of BLDC motors is mounted to one of the plurality of pipe threading tools and is operable to provide torque to a corresponding one of the plurality of pipe threading tools to rotate the corresponding one of the plurality of pipe threading tools relative to the pipe. A battery pack is supported by the stand and in selective electrical communication with the plurality of BLDC motors to provide electrical power to the plurality of motors.
