Abstract
A power tool includes a housing with first and second clamshell portions. A motor positioned within the housing is configured to rotate a motor shaft. A gear case coupled to the housing encloses a drive train to transmit torque from the motor shaft to an output drive extending from a front end of the gear case. A reaction arm coupled to the gear case limits rotation of the gear case. The power tool includes an interface assembly with an interface housing having a top portion positioned within the housing between the clamshell portions and a bottom portion extending outside the housing. The top portion includes a lens opening, and the bottom portion includes actuator openings. An interface circuit board coupled includes a display panel in line with the lens opening and switches positioned in line with the actuator openings. A lens is positioned within the lens opening.
