1. A power tool accessory for cutting elongated members comprising:
a housing having a rear end portion and a front end portion;
an input shaft at least partially received in the rear end portion, extending along an axis, and configured to be coupled to a tool holder of a rotary power tool;
an at least partially threaded shaft received in the housing and rotationally driven by the input shaft;
a blade holder configured to move axially upon rotation of the at least partially threaded shaft;
an unthreaded guide rod extending generally parallel to the at least partially threaded shaft and configured to be received in an unthreaded opening in the blade holder;
a cutting blade configured to be retained by the blade holder; and
a workpiece holder coupled to the front end portion of the housing and configured to receive an elongated member,
wherein, upon rotation of the input shaft in a first direction, the at least partially threaded shaft rotates, causing the blade to move axially at least partially into the workpiece holder to cut the elongated member.
