ABSTRACT:
A pipe cutter is designed for cutting a pipe from the inside by insertion of the pipe cutter through an open end of the pipe. The pipe cutter includes an elongated hollow sleeve with first and second ends in which an elongated shaft which is longer than the hollow sleeve is located for rotation. One end of the elongated shaft is adapted for connection to a source of rotational power; and the lower or opposite end of the elongated shaft is attached to a rotary saw blade. A centering housing is located between the first and second ends of the hollow sleeve and includes a mechanism for moving the sleeve and the elongated shaft located in it from an initial position with the saw blade out of contact with the interior of the pipe to a position radially outward from the central axis of the pipe to engage and cut the pipe through a circular or orbital motion of the pipe cutter.
