ABSTRACT:
A drill bit having a plurality of cutters on its lower surface, each of which can having a plurality of PDC cutter elements disposed thereon. The cutting surface on each of the cutters is mounted in in an orientation that allows drilling of oversize boreholes which enables the drill bit to be turned more easily to facilitate the boreholes being drilled on a smaller radius. The placement of the cutters on each of the blades enables the drill bit to drill both vertically and laterally.
