Claim:
1. A surgical cutting system comprising: a drill guide including a guide portion having a guide portion body defining first and second longitudinal ends spaced from one another along a longitudinal direction, and first and second transverse ends that extend between the first and second longitudinal ends and are spaced from one another along a transverse direction that is substantially perpendicular to the longitudinal direction, the drill guide further including an attachment member between the first and second transverse ends and configured to couple the drill guide to a trial implant, the drill guide defining a guide hole that extends through the guide portion body along a guide hole axis from the first longitudinal end to the second longitudinal end, the guide hole defining first and second closed ends that are spaced from one another in the transverse direction, wherein the first and second closed ends are disposed between the first transverse end and the attachment member, and the guide hole is elongate from the first closed end to the second closed end in a plane that is perpendicular to the guide hole axis, the guide hole defining a first position, a second position, and at least one mating feature, the first and second positions spaced from one another along the transverse direction; a drill guide sleeve that is selectively receivable in the first position and the second position of the guide hole and that mates with the at least one mating feature so as to fix the drill guide sleeve in one of the first and second positions, the drill guide sleeve defining a sleeve body, a first stop member, and a sleeve opening that extends through the sleeve body; and a drill bit configured to be at least partially received in the sleeve opening, the drill bit defining a second stop member that is configured to abut the first stop member so as to limit movement of the drill bit through the sleeve opening along the guide hole axis to a maximum cut depth when the drill bit is at least partially received in the sleeve opening and the drill guide sleeve is partially received in the guide hole, wherein the guide hole is oriented relative to the trial implant when the drill guide is coupled to the trial implant such that the guide hole is configured to guide the drill bit to advance through the guide hole into a vertebral body so as to create a drilled opening in the vertebral body.
