ABSTRACT:
A pipe cutter especially adapted to cut soil pipes and the like from the outside in a very narrowly confined space.
The soil pipe of a bathroom commode projects outwardly from the wall and is capped a short distance from the wall. The present cutter is mounted on the existing mounting bolts of the soil pipe assembly. The cutter assembly comprises an input shaft which may be driven by a separate electric drill which turns a pinion geared to a ring gear, driving it at slower speed, the latter having mounted, on the inner perimeter, a spring-loaded cutter blade for projecting the blade radially inwardly under spring action during rotation of cutter blade.
