Abstract
A pipe cutting apparatus comprises a housing with a pipe passage through the housing, a rotatable collar and a rotatable ring both of which rotate about the pipe passage and a pipe cutter mounted on the collar. The pipe cutter is movable inwardly toward and outwardly away from the pipe passage and has a drive gear which engages the ring such that differences in rotating speeds between the collar and the ring operate the drive gear to produce movement of the pipe cutter.
