US Patent 11136839 Bit breaker box

A bit breaker for coupling a drill bit to a drilling string includes a base defining a central opening and a wrench portion extending upward from the base. The wrench portion has two opposing lateral sides and an end wall that define an open interior that receives a shank of a drill bit. The open interior and the central opening are in alignment. A handle is coupled with the base and is movable between a storage position in which a top of the handle is positioned below a top surface of the wrench portion and a toting position in which the handle extends upward with the top of the handle positioned above the top surface. A gate is movably positioned between a retaining position in which the gate encloses the open interior of the wrench portion and an access position that provides lateral access to the open interior.
