Abstract

A drill bit for drilling a hole through earth and hard materials, the drill bit including a bit body having an inner bore and a cutting head at a cutting end, the cutting head including a center portion with one or more apertures extending from the cutting end to the inner bore, a perimeter portion projecting radially outward to form a plurality of blades divided by a plurality of junk slots, a cutting face, and a plurality of cutter receptacles spaced about the cutting face. A plurality of cutters with cutter tips terminating in points are in mounted into the cutter receptacles at a pitch angle relative to the cutting face, and with the plurality of cutter points together defining a projected cutting surface.
