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.

A pipe threader includes a housing, an electric motor, a battery, a die holder, and a die locking mechanism. The die locking mechanism receives torque from the electric motor and rotates as a result. A cutting die is received in the die holder and the locking mechanism rotationally locks the cutting die in the die holder. The locking mechanism includes a first lock ring and a second lock ring. The pipe threader includes a drive assembly including an electric motor, a multi-stage planetary transmission that receives torque from the motor, and a worm drive that receives torque from the transmission. The pipe threader includes an inertial measurement unit and an electronic processer. The processor receives data from the inertial measurement unit, generates a relative position of the pipe threader by applying a Kalman filter, determining whether the relative position exceeds a threshold, and decreases the motor speed in response.

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.

A portable pipe threader includes 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 including an electric motor operable to provide torque to the pipe, and a lubrication system removably coupled to the housing, the lubrication system including a reservoir for holding a lubricant and a pump supported upon the reservoir and configured to draw the lubricant from the reservoir, the pump being powered by the drive assembly.

A device (44) for forming a thread in a workpiece has a housing and a plurality of tool receptacles (2) rotatably and displaceably mounted in or on the housing for a respective thread-forming tool, wherein a linear drive and a rotary drive for the tool receptacles (2) are integrated into the housing.

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.

A modification system for the modification of elongated pieces of stock may include a powered tool for modifying, or altering the piece of elongated stock, and a support device for supporting a position of the elongated stock relative to the powered tool. An arrangement of the components of the powered tool may provide for ergonomic balance of the powered tool. The support device may include a clamping device that clamps, or holds the elongated stock, and an adjustment device that adjusts a position of the clamping device based on a size of the elongated stock. The support device may include a latching device that maintains the position of the clamping device relative to the stock. A reaction arm may inhibit rotation of the tool relative to the stock during operation. A biasing device may provide for application of an axial biasing force on the stock, to initiate operation.

A power tool for forming threads includes a tool housing with a motor housing portion having a first handle, a battery receptacle configured to receive a battery, a motor housing portion with a motor, a transmission housing portion with a transmission, and an operating head portion arranged along a tool axis. A cutting head is at least partially received in the operating head portion and rotates about a rotational axis transverse to the tool axis to form threads in a workpiece. A second handle is coupled to the operating head or the tool housing adjacent the operating head. When power is applied to the motor, the motor rotates and the transmission transmits torque from the motor to rotate the cutting head. A center of gravity of the power tool is positioned at a portion of the tool housing substantially aligned with the second handle.
