Abstract: The multi-purpose plumbing tool is designed specifically for use with copper tubing to enable cutting and preparation of cut ends and associated fittings for soldering on a job site. Basically, the tool includes a frame supporting a motor driven high speed circular pipe saw. A handle and pipe vise structure in turn is pivoted as a unnit to the frame in such a manner that a pipe gripped in the vise can be swung downwardly and forwardly into engagement with the circular saw blade and thereby cut. The same motor driving the saw blade is utilized to drive rotary wire brushes for cleaning the outside of cut ends of the pipe and the inside of fittings. Appropriate deburring and reaming operations are also performed by these rotating structures. Finally, flux applicator heads are provided to treat the cleaned pipe end surfaces and inside the fittings with appropriate flux paste preparatory to soldering, these flux applicator heads being held on the frame and supplied by paste from a cartridge carried in the frame.
