ABSTRACT:
A pipe cutter for cutting the wall of a pipe from within the bore of the pipe. The cutter includes a blade and mechanisms for supporting the blade within the pipe to be cut, urging the blade outwardly of the pipe to engage it with the pipe wall and moving the blade relative to the pipe so that the blade cuts the wall. The cutter may include an expansible gripper assembly for engaging the pipe wall to retain the blade against movement axially of the pipe during the cutting operation. The gripper assembly is preferably operative upon operation of the blade movement mechanism. The blade may be a circular saw, the blade movement mechanism may be arranged to move the saw in orbital fashion around the axis of the pipe and the gripper assembly may be connected to the blade so that the gripper assembly prevents rotation of the saw about its axis during the cutting operation. When this arrangement is utilized, all of the teeth of the saw are successively engaged with the pipe wall.
