Abstract
Portable cutting apparatus is disclosed for turning either the outer peripheral surface of a cylindrical workpiece, such as a journal, or the annular end face of a tubular workpiece, such as the flanged mouth of a retort or the like. A hollow drum, which is rotatably driven around a fixed shaft, carries a change speed gear box for reciprocating a tool holder also carried by the drum. The tool holder is an interchangeable attachment for the drum and depending on the attachment used, the tool is movable in planes either normal to or concentric about the axis of rotation of the drum. The gear box is geared to the fixed shaft and therefore driven by rotation of the drum.
