Claim 9:
10. A method of forming a bone tunnel, comprising the steps of:
providing a drill bit having a shaft extending along an axis and positioned within a body, and a cutting tip pivotally mounted to said shaft and moveable between a cutting tip first position where said cutting tip is aligned along said axis and a cutting tip second position where said tip is perpendicular to said axis, the body being interlocked with the shaft via a track on one of the body or the shaft accepting a pin extending from the other of the body or the shaft, wherein relative movement of the body and the shaft is controlled by the pin being accepted by the track and moveable therewithin between a pin first position and a pin second position;
advancing the drill bit with said cutting tip in the cutting tip first position to form a first bore having a first diameter through a bone;
moving said cutting tip into the cutting tip second position after said cutting tip has passed through the bone by moving the pin from the pin first position to the pin second position; and
partially withdrawing said drill bit through said first bore in said bone to form a second bore having a second diameter that is larger than the first diameter.
