A drain cleaning device includes a power unit and a drum assembly coupled to the power unit for rotation by the power unit. The drum assembly includes a base, a cable received in the base that is configured to be fed from the base and rotated to clean a drain, and a cover releasably coupleable to the base. The drum assembly includes a plurality of taper locks releasably coupling an outer peripheral portion of the cover and an outer peripheral portion of the base. Each of the taper locks is moveable between a locked position in which the cover is retained on the base and an unlocked position in which the cover is removable from the base. Each of the taper locks being biased toward the locked position.

A multi-speed, power-driven tool may include a transmission mechanism that transmits power from a motor to an output device. A speed selection mechanism may be coupled to the transmission mechanism, to control a speed reduction through the transmission mechanism, and an output speed of the tool. The transmission mechanism may employ a compound, stepped, planetary gear assembly, to provide for an axially compact arrangement of transmission mechanism components, to reduce an axial length of the tool. The speed selection mechanism may employ a multi-staged grounding device, corresponding to the reduced axial length of the transmission mechanism.
