A tool for use in fusing an outlet fitting in the side wall of a plastic pipe has a base with three perpendicular guide rods. A movable plate is reciprocated on the guide rods in response to manual operation of a rack-and-pinion. The movable plate has a hole oriented to align a drill adapter and an outlet fitting adapter which are interchangeably inserted into the hole on an axis extending through a predetermined point on the longitudinal axis of the pipe. A retractable ratchet strap tightly girts the pipe to secure the tool against the pipe. The ratchet strap assures that the tool always maintains its original orientation on the pipe and the hole assures that interchanged drill and outlet fitting adapters are always returned to their original orientation in the tool. Therefore, the outlet fitting is always fused in its proper orientation in the pipe.
