Abstract
A tool for tapping from a branch pipe into a main pipe to establish communication between the pipes. The tool has a bit for cutting a hole in the main pipe which is secured to an upstream end of a shaft for transmitting torque to the bit. The tool has a branch-engaging member engaged to the branch pipe adjacent to the downstream end of the branch pipe. The shaft has a threaded section engageable with a threaded section of the branch-engaging member so that as the shaft is rotated, the bit is driven along the longitudinal axis of the branch pipe toward the main pipe.
