ABSTRACT:
An unwrapping bit for solderless wrapped connections of flexible conductor wire comprising a tubular member having a conical recess in one end face and a terminal receiving bore coaxial with the conical recess. Opposed longitudinal slots as well as transverse slots in the bit intersect the recess and form ledges for engaging the coiled end of a flexible conductor wire. The conical recess may have a reentrant shoulder portion adjacent the bit end face for retaining the conductor wire coils in the recess as they are unwound from the terminal.
