<p>A device for augering a conical hole in a solid medium that includes a first elongated member (54) extends along a longitudinal axis (x) and a cutting blade (60) having a cutting section (64) and a non-cutting section (66) coupled to the first elongated member (54). The rod (54) is adapted to be rotated about the longitudinal axis (x). A motor (212) is coupled to the first elongated member (54) which rotates the cutting blade (60) about the longitudinal axis. A shroud (80) is provided through which the first elongated member passes. The shroud attaches to a hydraulic unit (100). Activation of the hydraulic unit (100) causes the first elongated member (54) to move in a longitudinal direction, which causes the cutting blade (60) to move in a radial direction thereby forming a conical hole in a solid medium. The device is used for forming holes used in foundation and anchors. Also disclosed is a method of operation of the device to form a conical hole in solid media.</p> |
