Abstract: A power tool including a housing having a handle configured to be grasped by a user, a motor supported by the housing, a driving gear rotated by the motor, and a driven gear engaging the driving gear to be rotated by the driving gear about a rotation axis. The power tool also includes a pin extending from the driven gear and offset from the rotation axis and a spindle having a yoke coupled to the pin to translate rotation of the driven gear into reciprocating motion of the spindle. A notch is formed in an outer periphery of the yoke to provide clearance for the driving gear as the spindle is driven by the pin.

Abstract: A powered threaded rod cutter includes first and second cutting dies, an electric motor, a planetary transmission positioned downstream of the motor, a drivetrain for converting a rotational output of the transmission to a pivoting movement of the first cutting die, and a clutch mechanism for redirecting torque from the motor away from a drivetrain and the first cutting die in response to the first cutting die seizing during a rod-cutting operation. The clutch mechanism includes a ring gear in the planetary transmission, and a spring that rotationally affixes the ring gear below a predetermined threshold of reaction torque through the drivetrain and permits rotation of the ring gear above the threshold.
