Abstract
A portable machine tool for cutting pipe ends located within a confined area includes separable motor and tool housings, a mandrel and associated support shaft for coupling the tool to the pipe workpiece, a rotable cutter head movable coaxially around and axially along the mandrel support shaft for feeding the tool towards the workpiece, and a feed actuator arrangement that presents a very slim cross-sectional profile for the tool, the feed actuator including a thumb wheel that can be manipulated when the motor housing is grasped.
