Several wire wrapping device embodiments are disclosed, each of which incorporates a releasable bit-locking mechanism associated with the bit-sleeve assembly thereof. The locking mechanism is mounted on the stationary sleeve of the device, and is actuated to responsively effect the release of the bit for rotation, prior to each successive wire wrap operation, only upon a terminal to be wire wrapped being inserted to a predetermined, but adjustable, depth within a terminal-receiving recess formed in the forward end of the bit. Such a mode of operation insures that each wire wrap is accurately positioned on each successive terminal. The bit-locking mechanism also may be optionally employed to responsively actuate an associated switch to either directly, or conditionally (i.e., in conjunction with the actuation of a power source-connected trigger switch), effect the energization of the drive motor coupled to the bit of a wire wrapping device.
