Abstract
A cutting device for use with installation of helical ground anchors designed to cut through rock. The invention has carbide steel cutting tips attached to the distal end of a shaft extending below the end in order to make a first cut through rock along the axis of rotation of the shaft. Helically shaped plates are attached to the shaft at a distance above the shaft set of cutting tips. Attached along the outer edge of the helix are additional carbide steel cutting tips that extend below the bottom surface of the helix and cut along the axis of rotation of the shaft. The present invention allows for the installation of helical ground anchor supports at proper depths without deviation, in situations where the path is obstructed by rock or other hard materials.
