Abstract
The present invention relates broadly to pneumatic tools, such as a sander, that provide an optimum output speed and has significant stall torque to reduce the risk of the tool from stalling during use. The tool includes a coupled gear set that drives an output accessory, such as an abrasive pad, at an optimum speed without loss of power or power reduction, and with an amplified stall torque. The coupled gear set may include a first gear set that functions as a speed reducer, and a second gear set that functions as a speed increaser.
