A self-aligning tapping tool comprises an elongate handle having a longitudinal
counterbore through a first end. A tap is received in the counterbore. A collar
is operatively secured to the tap. The collar is slightly smaller than the counterbore
to enable slidable movement and to prevent rotation of the tap relative to the
handle. A retainer is secured to the handled at the first end to retain the collar
in the counterbore and has a center opening receiving the tap. A biasing spring
in the counterbore biases the tap and the collar outwardly to extend the tap when
the handle is turned to thread a hole in a work piece.
