A wire wrapping device having a rotatable bit assembly comprised of a sleeve and a bit. A transversely oriented bore in said bit mates with an aperture through one wall of the sleeve and has a pin inserted in said bore which extends into said aperture to prevent rotational movement between the two. The aperture in the sleeve is formed as a vertical slot which along with the pin controls the axial movement of the sleeve with respect to the bit. One end of the bit has a longitudinally extending groove along its outer surface and also a longitudinally extending groove along its surface and also a longitudinally extending bore formed internally from the outer surface of the bit for receiving a terminal pin upon which the wire is to be wound. The bit also has a channel extending completely across its end face passing over both the mouth of the groove and the bore. The sleeve has bit support gripping means formed adjacent its one end, with its other end having an elongated neck whose intermediate portion has part of its circumferential surface longitudinally cut away. Formed at the tip of the neck is a hook finger for capturing the end of a wire which is to be wound upon a pin terminal. The hook is brought into operation after the wire is oriented transversely to the intermediate portion of the neck at a position somewhere between the channel in the end face of the bit and the mouth of the finger hook. As the sleeve is axially drawn upwardly around the bit the mouth of the hook engages the wire and draws it into the channel located in the open face of the bit. Continued upward movement cams the tip of the wire into the groove along the outer surface of the bit, thus placing the apparatus in readiness for winding of the wire upon a terminal pin.
