ABSTRACT:
A sanitary sewer root clean out tool for use with a plumber's snake is formed by an elongated helical member having a forward compacted root penetrating end portion supporting a pair of laterally pivoting blades which are retracted during forward movement of the tool and expand laterally in a root cutting action when moved rearwardly. A root cutting assembly transversely surrounds an intermediate portion of the elongated helical member and is angularly rotated thereby by forward and rearward movement of the helical member relative to the cutting assembly to sever roots surrounding the helical member by blades radially projecting outward from the periphery of the helical member as the latter is longitudinally reciprocated.
