PILE CAP AUGER
An attachment for a rotary pile rig comprising of a quick connection shaft as the drill stem, tapered-helical flights that reduce in diameter at a steep angle to terminate at a smaller diameter, a centralizer fixed to the drill stem below the flighting, and a drill tip terminating a distance below the centralizer. The centralizer is inserted into a pre-bored pile preventing the auger from oscillating offline during drilling operations. As the rotary drill rig applies pressure and torque, the tapered-helical flights ream the top of the pre-bored pile shaft to a larger diameter. The sharp angle of the flights produce a steeply sloped transition between the larger pile cap diameter and smaller pile shaft diameters. The steep shoulder prevents the retention of trimmings from the remainder of the pile installation operations creating an acceptable concreting surface at a determined depth below grade.
