A profiled end cut is applied to a length of stock pipe in an apparatus wherein the pipe (13) is rotated by a drive head (12) with a plasma cutter (81) moved axially on a trolley (14) in synchrony with rotation under control of a guidance system (3). The guidance system (3) follows a desired pattern to effect two adjoining end cuts in a single continuous operation. Pipe handling is by two sets of rollers, a support set (15) permitting rotation and a lifting set (104) to enable axial movement.
