ABSTRACT:
A hand-held deburring tool comprising a handle member with a distal end having a cavity therein, within which a unirotary ratchet bearing is disposed. The unirotary ratchet bearing has a deburring tip element-receiving bore therein for engaging the shank of a deburring tip element positioned therewithin. A support element is mounted in a lower portion of the cavity in the handle member, for abutting contact with a proximal shank extremity of a deburring tip element positioned within the bore of the unirotary ratchet bearing. This tool accommodates a wide variety of deburring tip elements which are positionable with the proximal shank portion thereof in the bore of the unirotary ratchet bearing and with the proximal extremity thereof in abutting contact with the support element. The deburring tool may be usefully employed to remove burring or flashing from holes or openings in a wide variety of workpieces, e.g., aluminum plate stock.
