ABSTRACT:
An improved tool for wrapping wire around an electrical terminal to make an electrical connection. The tool includes a bit and a sleeve for receiving the bit. One end of the bit has a connecting member for coupling the bit to the chuck of a hand-held drive motor. The opposite end of the bit is provided with a tip having a recess axially aligned with an axially extending groove formed in one side of the main body of the bit. A discontinuity between the recess and the groove is defined by a ridge having a pair of relatively convergent edges which extend toward the axis of the bit and terminate at a notch axially aligned with the bottom of the groove in the bit body. A crescent shaped projection extends axially outwardly from one side of the tip to wrap the end of the wire against the terminal at the end of a wire wrapping tool. The sleeve has an enlargement at the end near the tip for receiving one end of a wire and guiding it to the groove and outwardly through a side window in the sleeve before rotating the bit. The window is surrounded by a cutting edge which cuts the excess part of the wire when the bit starts to rotate. The sleeve has a stationary bearing therewithin near the enlargement to cause a number of functions to be performed when the bit commences to rotate in the sleeve.
