ABSTRACT:
A tool for stripping an insulated wire and/or wrapping the wire around a terminal tag in which a sleeve member has a bit member axially slidable therein and the bit includes a longitudinal aperature adapted to receive a terminal tag; the bit member including an intermediate recess and a groove or channel in the side of the bit member between a free end and said recess; a shearing edge or face substantially adjacent the junction of said groove or channel with said recess; the sleeve member having a second insulating shearing edge or face within the sleeve member, axially at a predetermined distance from the free end of the sleeve member so that the bit member when axially advanced a portion of the recess protrudes beyond the free end of the sleeve member and an insulated wire inserted between the sleeve and the bit stripped of its insulation when the bit is withdrawn axially into the sleeve due to coaction between the shearing edges; the axial movement of the bit partially stripping a predetermined length of insulation from the wire; the longitudinal aperture in the bit member then being engaged by the terminal tag and rotation of the bit member causing the stripping wire to be wrapped around the tag.
