Systems and methods for braking a power tool using a stamped brake resistor. The power tool includes a motor, a trigger configured to be actuated, and a brake switch coupled to the motor. A brake resistor assembly is selectively coupled to the motor via the brake switch and includes a stamped brake resistor. The stamped brake resistor includes a terminal portion and a resistive portion. The resistive portion includes a planar serpentine path. A controller including an electronic processor and a memory is coupled to the trigger, the motor, and the brake switch, and is configured to control power delivered to the motor based on a position of the trigger, determine to brake the motor during operation of the motor, and activate, in response to determining to brake the motor, the brake switch to connect the stamped brake resistor to the motor.

A reciprocating saw includes a housing, a motor positioned within the housing and configured to drive a reciprocating saw blade, and a shoe coupled to the housing. The shoe is configured to engage a workpiece. The reciprocating saw also includes a proximity sensor configured to detect the workpiece when engaged with the shoe. The proximity sensor is positioned on a forward end of the housing in a facing relation with the workpiece. In response to the proximity sensor detecting formation of a gap between the shoe and the workpiece, the proximity sensor is operable to deactivate the motor.
