Abstract
The present invention relates to a power tool which comprises a rotary tool for working on a work piece and a motor having a longitudinal shaft axis. A motor housing supports the motor and a transmission mechanism for transferring energy from the motor to the rotary tool. A handle assembly is provided for moving the power tool with respect to the work piece. The handle assembly has a switch positioned thereon to electrically connect the motor to a power source. The handle assembly is rotatable relative to the rotary tool housing during operation of the motor.
