A drill bit includes a body extending along an axis and including a point end and a shank end. The drill bit also includes a first helical portion, having a first helix angle relative to the axis. The drill bit also includes a second helical portion, having a second helix angle relative to the axis which is different from the first helix angle.
A bone drill extending along an axis has (1) a stabilizing point with first and second cutting edges which extend to a tip, conical wall sections and flutes on opposite sides of each of the first and second cutting edges and (2) first and second lands extending radially outwardly from the conical wall sections, each land having a radially outwardly extending cutting edge.
