Abstract: The present invention provides a global drilling system comprising a crown bit, a driver drill bit and a square drill bit. The crown bit has a tubular body with an inner surface and an outer surface, wherein the inner surface circumscribes a hollow passageway, and a pair of projections extending into said hollow passageway. The pair of projections are positioned substantially opposite one another on said inner surface. The driver drill bit has a drilling head with a pair of cut-away portions positioned substantially opposite one another and a pair of locking surfaces adapted for engaging the projections on the crown bit. The square drill bit has a drilling head with two tapered cut-away portions positioned substantially opposite one another. Each cut-away portion corresponds to one of the pair of projections such that the drilling head is able to pass through the hollow passageway of the crown bit.

Abstract: An apparatus adapted to exert traction on the frame of a vehicle to straighten or reshape the same and characterized by having the front or forward portion free of the winch and of the actuating mechanism for the winch, by allowing to operatively reach a frame at a point higher than the apparatus and close to the floor, by a chain extending along the cable and forming a safety guard for the operator, and by being portable in the trunk of a car. This apparatus includes a base plate, wheels rollably supporting the base plate and including a swivelling wheel to easily position the apparatus on the floor relative to a vehicle, a removable post, a winch rearward of the post, a cable running on a cable guide pulley mounted on the upper end of the post, a chain anchoring the base plate on the floor, and another chain holding the post upright and forming a guard over the cable between the winch and the post.
