Abstract:
1. A drill bit comprising: a shaft having a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end; a cutting head located at the distal end of the shaft and having at least one helical flute, wherein a maximum diameter as defined by outer surfaces of the at least one helical flute is the same at a proximal-most region and a distal-most region of the cutting head, wherein the cutting head further includes a cutting edge and an offset leading spur, the at least one helical flute defining a helical angle of at least 45 degrees with the longitudinal axis of the shaft, the offset leading spur defining a first cutting diameter that is equivalent to a second cutting diameter defined by the cutting edge; a tapered point located along the longitudinal axis at a distal end of the cutting head for guiding the drill bit; and wherein a portion of the shaft located adjacent and proximal to the cutting head has a reduced diameter relative to the remainder of the shaft.
