Abstract: A drill assembly and method for reducing plunge of a drill bit upon breaking through a workpiece. The drill assembly contains a motor to advance and retract the drill bit, the motor is controlled by a control unit in a feedback loop to achieve a desired stiffness. The control unit determines when the drill bit breaks through the workpiece and stops or retracts the movement of the drill bit.
