Abstract

This invention provides a system for using a portable tool for assisting the making of holes in installed pipes, such as water pipes and the like, to prepare for interconnected piping. Such system preferably utilizes a hole saw guide bushing which is contained in a clamp-head at the end of the fixed jaw of a "Vise-Grip.TM."-like device. Such clamp-head accommodates various sizes of guide bushings and hole-saws for making various size holes in various size pipes. Other features assist accurate hole positioning, e.g., horizontal and vertical levels, center marks, and V-shaped holding surfaces on the clamp-heads.
