ABSTRACT:
A portable tube cutting and finishing device employs a manual electrically operated power drill supported on a frame and driving a pair of tube drive and support rollers in a cradle arrangement. A tube supported by the rollers is rotated thereby through the operation of a pair of gears respectively associated with the rollers, and a gear train with an initial gear being rotated by on output member and a small universal connector driven by the power drill. The power drill is detachably assembled with the frame and may be used for other purposes. A tool carrier driven by one of the gears in the gear train, is of hollow cylindrical configuration with opposite ends respectively open and closed. Mounted within the closed end of the carrier is a conventional reamer and adjacent thereto a hollow cylindrical burnishing tool serves to lightly machine an external end portion of a freshly cut tube. Thus, reaming, resulting in internal deburring and external burnishing can be accomplished simultaneously and substantially instantaneously on the tube end portion.
