1. A portable bending tool, comprising:
a frame including a ground engaging base and an upright portion extending upwardly away from the ground engaging base when the ground engaging base is positioned on a supporting surface;
an electric motor operably coupled to the frame;
a removable, rechargeable battery pack in electrical communication with the electric motor;
a reductive gear set operably coupled to the frame, and configured to reduce a rotational output of the electric motor between an input shaft and an output shaft;
a rotatable bending form defining an arcuate bend channel, the rotatable bending form operably coupled to the output shaft of the reductive gear set, wherein rotation of the output shaft causes rotation of the rotatable bending form relative to the frame;
a tube guide member operably coupled to the frame to guide and support a portion of tubing during rotation of the rotatable bending form, wherein the tube guide member is movable to a desired distance from the output shaft while maintaining contact with the frame; and
a handle operably coupled to the upright portion, wherein the rotatable bending form and the tube guide member are operably coupled to the upright portion between the ground engaging base and the handle.
