I am wondering if a dremel or its counterpart is worth having for pipe maintenance and cleaning. I was hoping to get into restoring estate pipes. I found one with an adjustable speed of 5000-35000 rpm. I know the lower speed the better for our work. I was thinking it could be used to polish stems, sand stems, and ream the inside of bowls. Has anyone tried this (reaming) with the sander attachment using either the cone or the standard cylinders? My guess is SOMEONE has tried it, did it work? Can you buff with a dremel?
