ABSTRACT:
An apparatus for cutting a pipe includes a housing member comprising a cutter body member having a collar. The cutter body member is configured at one end for insertion into a portion of the pipe to be cut. A piston chamber within the cutter body member is in communication with an aperture in the surface of the cutter body member. The collar preferably is a flange which is positioned at the other end of the cutter body. The flange extends in spaced relationship about the cutter body toward the pipe portion to be cut and is configured so as to overlay the portion of the pipe to be cut. A cutter wheel is rotatably disposed on a piston which is slidably moveable within the piston chamber. A hydraulically controlled mechanism is provided for advancing the cutter wheel toward the portion of the pipe to be cut so as to provide for cutting of the pipe at a predetermined depth of penetration. A rotary mechanism is also provided for rotating the housing during the penetration of the cutter wheel so as to permit the cutter wheel to circumferentially cut the portion of the pipe at the predetermined rate.
