This invention relates to a wire wrapping tool to perform the disorderly arranged wiring of pin contact fields having high wiring density. An arrangement is provided for spreading the wiring adjacent the terminal pin being wrapped. Four spreading fingers generally parallel to the wrap gun bit are spaced outwardly of the bit. These fingers are secured by a ring member. Lever action of the fingers is produced by a second ring adjacent the upper edges of the fingers, the upper ring being movable axially to lever the fingers.
