Abstract

A bone access instrument comprising a shaft having a first shaft portion and a second shaft portion. The first shaft portion has a first diameter, a proximal end, a tapered distal end including at least three straight cutting edges being equally spaced circumferentially about the tapered distal end, and at least three flutes extending from the tapered distal end toward the proximal end in a parallel relationship to one another. The second shaft portion has a second diameter and a tapered distal end. The second diameter is less than the first diameter, and the second shaft portion extends axially from the distal end of the first shaft portion.
