An in-line reversing mechanism for use with hand-held power tools comprises two coaxially juxtaposed epicyclic gear trains having a common carrier which may alternately be locked to or released from an outer cage to accomplish the bidirectional transmission of rotational power. The complete reversing mechanism is housed in a generally cylindrical body suitable for mounting between a conventional unidirectional motor and gear head or powered device. Forward or reverse output rotation is selected by the tool operator by moving an annular collar positioned on the periphery of the reversing mechanism to the front or rear of the mechanism.
