A power tool including a motor configured to rotatably drive an output shaft, a variable motor speed control input, a motor speed limit input, and a motor controller. The motor controller includes an electronic processor and a memory configured to store instructions. When executed by the motor controller, the instructions configure the motor controller to detect a motor speed limit from a setting of the motor speed limit input, and detect a variable speed control setting from the variable motor speed control input. The motor controller generates a motor speed control signal for driving the motor based on the detected motor speed limit and the detected variable motor speed control setting, and transmits the motor speed control signal to a motor driver circuit configured to drive the motor at a speed based on the motor speed control signal.
