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.

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.

Portable pipe threader

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.

A closet auger includes an elongated casing member extending along an axis, a cable drum rotatably coupled to the elongated casing member, a drive coupling connected to the cable drum to rotate the cable drum about the axis, and a flexible cable having a first length stored within the cable drum and a second length extending through the casing member and out from the casing member. The closet auger also includes a feed assembly having a handle movable along the casing member and a plurality of gripping members carried by the handle. Each gripping member has a first end pivotally coupled to the handle and a second end biased radially outward from the handle. The plurality of gripping members is circumferentially spaced about the axis and operable to selectively engage the flexible cable to push the flexible cable into or pull the flexible cable out of the cable drum.

A drain cleaning machine for moving a snake in a drain. The drain cleaning machine includes a rotating shell, a motor, radial drive mechanism, a translate mechanism, and a selection mechanism. The selection mechanism includes an actuating lever moveable between an activated position and a deactivated position, a selection plate moveable between a radial drive position and a translate position, and a push plate. The push plate is moveable in a first direction relative to the selection plate in response to the actuating lever moving to the activated position, and is moveable in a second direction relative to the selection plate in response to the actuating lever moving to the deactivated position. When the selection plate is in the radial drive position and the actuating lever is moved to the activated position, the push plate moves toward the selection plate to switch the radial drive mechanism to an engaged state.

An apparatus for creating holes in a workpiece includes a knockout punch tool having a movable piston. The apparatus also includes a draw stud assembly having a connector attachable to the movable piston, a draw stud, and a quick connect mechanism including mating first and second thread segments on the connector and the draw stud, respectively. The connector and the draw stud are movable between a first relative orientation where the mating first and second thread segments are misaligned to permit axial movement between the connector and the draw stud, and a second relative orientation where the mating first and second thread segments are aligned and engaged to inhibit axial movement between the connector and the draw stud.
