ABSTRACT:
A device for augering a conical hole in a solid medium that includes a first elongated member that extends along a longitudinal axis and a cutting blade having a cutting section and a non-cutting section coupled to the first elongated member. The rod is adapted to be rotated about the longitudinal axis. A motor is coupled to the first elongated member which rotates the cutting blade about the longitudinal axis. A shroud is provided through which the first elongated member passes. The shroud attaches to a hydraulic unit. Activation of the hydraulic unit causes the first elongated member to move in a longitudinal direction, which causes the cutting blade to move in a radial direction thereby forming a conical hole in a solid medium. The device is used for forming holes used in foundations and anchors. Also disclosed is a method of operation of the device to form a conical hole in solid media.
