A power tool includes a pipe holder, a knife pivotally coupled to the pipe holder, and a drive mechanism coupled to at least one of the pipe holder and the knife. The drive mechanism is operable to move the at least one of the pipe holder and the knife relative to the other of the pipe holder and the knife. The power tool also includes a motor coupled to the drive mechanism and a power supply electrically coupled to the motor to selectively power the motor for operating the drive mechanism.
