Systems and methods for braking a power tool motor using a magnetically susceptible fluid. One power tool includes a housing, a motor within the housing, a drive train coupled to the motor, a magnetically susceptible fluid located within the drive train, and an inductor within the housing and configured to introduce a magnetic field to the magnetically susceptible fluid. An electronic controller is connected to the motor and to the inductor and is configured to receive a signal to initiate a braking process, generate, in response to the initiation of the braking process, a control signal for the inductor, and provide the control signal to the inductor to control a viscosity of the magnetically susceptible fluid located within the drive train.
