Abstract
A tool with a rotatable guide head and a rotatable reamer head is pulled through old asbestos-containing pipe to break up the pipe. Liquid is supplied through a shaft between the guide head and reamer head so as to form a slurry mixture with the broken pipe. The slurry is removed through vertical bored relief holes. A drying compound is added to the slurry, which then hardens for easy disposal of the solidified waste material.
