Abstract

A power tool is advantageously configured to provide a rotating motion, an oscillating motion, and a reciprocating motion. The power tool includes at least one motor, which is operable to drive these three different motions at the same time. The power tool includes a rotating member, which is configured to output a rotating motion. The rotating member is configured to attach to and detach from a rotating accessory. The power tool includes an oscillating member, which is configured to output an oscillating motion. The oscillating member is configured to attach to and detach from an oscillating accessory. The power tool includes a pin, which is configured to output a reciprocating motion. The pin is configured to provide the reciprocating motion to a reciprocating accessory. The power tool is configured to provide a connected accessory with the corresponding motion during operation.
