Abstract
A power tool includes a housing, an output shaft, and a tool holder connected to the output shaft. A rotor assembly is attached to the output shaft that is configured to be acted on by a fluid flow through the housing to cause rotation of the output shaft. A centrifugally movable fluid flow governor is coupled to the output shaft that is configured to move outwardly from the output shaft to alter a force acting on the rotor assembly when the output shaft reaches a predetermined speed.
