Abstract A machine for use in cleaning the interior of a pipe constructed so as to include a hollow rod, a cleaning tool located on one end of the rod, means for moving the rod in a lengthwise direction coupled to the other end of the rod, means for rotating the rod as it is so moved and means for conveying a fluid through the rod to adjacent to the cleaning tool may be improved through the use of a combination drilling and brushing tool as a cleaning tool. Such a drilling and brushing tool includes a hollow sleeve attached to the end of the rod, brushing elements located on the exterior of the sleeve and a cutting blade located on the end of the sleeve remote from the rod, this blade having at least one hole leading to its surface which is in communication with the interior of a rod through the sleeve. The tool preferably has a flushing housing provided with ports leading from its interior to its exterior located between the sleeve and a rod.
