Abstract: In one aspect, a bit for removing a plug from a branch conduit extending from a main pipe has a boring head at a distal end portion of a shaft configured to bore a pilot hole in the plug. A catch on the shaft is configured to pass through the pilot hole and then engage the plug after the pilot hole is bored for pushing the plug proximally. A burr proximal of the boring head is configured to remove a portion of the plug to separate a removable section from a durable section of the plug. In a method of restoring fluid communication between a main pipe and a branch conduit, the bit bores a pilot hole with the boring head, separates the removable section from the durable section with the burr, and then with the catch, withdraws the removable section only.
