Abstract
A drain cleaner is disclosed having a housing with an interior region for storing a flexible drain cleaning cable. The drain cleaning cable can be extended from the drain cleaner and includes a rotatable member within a non-rotating sheath. The drain cleaner includes an engageable drive shaft coupled to the rotatable member. In certain versions, the drive shaft is coupled to the rotatable member through a torque limiting device such as a clutch. Upon engagement of the drive shaft with a rotary power source, a rotating distal end of the flexible cable can be used to dislodge obstructions in pipes. The interior region of the drain cleaner is configured to promote efficient coiling of the drain cleaning cable. The drain cleaner includes additional features for reducing wear of cable and components, and securely retaining the cable to the drain cleaner.
