ABSTRACT:
A portable tube end preparation tool includes an improved drive shaft for the cutter head of the tool, the drive shaft comprising a compact, three-piece assembly including two shaft portions that are axially aligned with respect to each other along the tool axis, and a coupling sleeve that fits over and joins the shaft portions together through threaded connections at adjoining ends of the shaft portions. The shaft portions and coupling sleeve cooperate with rolling bearing assemblies to react operational load forces into the tool housing through the bearing assemblies.
