Abstract
A power tool includes a body housing a motor with a first output shaft and an attachment for engagement with the output shaft. The attachment includes an output shaft which transmits rotational motion derived from the rotational motion of the motor and further includes a gear mechanism enabling a gear change in rotational speed between its input and output. A combination of the body and the attachment thereby provides a plurality of serially-coupled gear mechanisms.
