Abstract: A retractable drill chuck system that is capable of being attached to a drill and drill bit; it can detect the initial breakthrough of the drill bit in a material and is capable of retracting the drill bit right as the drill bit breaks through the material; it has torque, force, and acceleration sensors to detect the breakthrough event of a drill bit; it also has an electromechanical mechanism to retract the drill bit from the material once the breakthrough event has been detected by the system; the retraction mechanism has a permanent magnet holding solenoid that, when activated, releases stored mechanical energy to allow the drill bit to be retracted.
