ABSTRACT:
A portable end prep facer for refurbishing piping components in the field comprises a chuck to which a cylindrical mandrel is affixed where the chuck can be centrally mounted relative to a longitudinal axis of the piping component by affixing the chuck either to the I.D. or the O.D. of the piping component. A non-rotatable torque housing surrounds the mandrel and is longitudinally positionable there along. A cutting head assembly is journaled for rotation about the mandrel by means of bearings mounted in the torque housing and coapting with an annular race formed in a face plate of the cutting head assembly. Mounted on the face plate is a variable speed reversing drive mechanism that couples to a lead screw that forms a part of a tool support guide member. A sliding head is affixed to the lead screw and it, in turn, supports a tool bit holder that can be manually adjusted to set the depth of cut when machining the flange portion of a piping component being repaired.
