特徴とする電動パイプカッタ。a fixed outer ring that can be split into two and has a rotational drive shaft that is connected to a rotational drive source; a rotary inner ring that can be split into two and that is connected to the rotational drive shaft and rotatably supported within the fixed outer ring; , a vice device that is fixedly installed on one of the two halves of the fixed outer ring to clamp the pipe to be cut, and a vise device that is installed movably in the radial direction on the rotating inner ring and is pressed against the outer periphery of the workpiece to clamp the pipe to be cut. a holder for holding the blade, a cutting tool movably attached to the rotating inner ring in the radial direction, and an intermittent rotational feeding mechanism with a quick return device attached to the rotating inner ring and pushing the cutting tool in the radial direction, The intermittent rotational feed mechanism includes a feed screw shaft with a radially movable die wheel that is rotatably locked to the cutting tool, and a pair of half nuts constituting a quick return device that is removably screwed onto the feed screw shaft. An electric pipe cutter characterized in that the feed screw shaft is intermittently rotated to feed the cutting tool each time the die wheel comes into contact with pawl means provided on the fixed outer ring.
