A thread-cutting die head includes a die carrier, defining a central axis, for supporting a plurality of thread-cutting dies, a cam plate coaxial with the die carrier including a plurality of cam members for engaging with the plurality of thread-cutting dies, and a locking system including a positioning screw extending through an arcuate slot in the cam plate, a bushing surrounding the positioning screw, and a handle threadably coupled to the positioning screw configured to impart a force against the bushing to press the flange portion of the bushing against the first surface of the cam plate, thereby developing a frictional force between the bushing and the cam plate to lock the rotational position of the cam plate relative to the die carrier.

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 die head for cutting threads in a pipe. The die head includes a drive portion, a die retention portion, a cap, and a plurality of windows. The drive portion has a plurality of recesses configured to receive torque from a pipe threading machine. The die retention portion includes a plurality of die posts. Each die post is configured to receive a die having teeth for cutting the threads in the pipe. The cap is coupled to the die retention portion. Each window is defined between each pair of adjacent die posts and the cap. An end of each die adjacent the cap is visible through a corresponding window of the plurality of windows such that all of the teeth of the die are visible through the corresponding window.

A method, system, apparatus, and/or device for threading a pipe may include: a housing including a cavity to store a pipe threading machine. The housing includes a door to open to provide access to the cavity and an opening along a side wall of the housing to receive an end of a pipe. The pipe threading machine located within the cavity. The pipe threading machine is to cut the pipe, ream the pipe, and thread the pipe using one or more attachments. An oiler is configured to apply oil to the pipe and the one or more attachments as the pipe threading machine cuts the pipe, reams the pipe, and threads the pipe. An oil catching system is located within the cavity below the oiler and the pipe threading machine to catch oil dripping or spraying from the pipe threading machine, the oiler, or the pipe.

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.
