Auger for boring and weeding

Abstract

An auger to assist in ground burrowing or mixing paint or concrete, is used by attaching it to an electric or cordless power source. The major advantages over previous augers are: a hex head design prevents slipping in the drill chuck, an offset boring tip provides better digging, and a removable extension allows for the digging holes from a sitting or standing position possible without straining. The cutting edge of the auger's discs is sharpened and provided with a serrated edge for easier digging in hard soil. A single spring pin lock connects a first shaft to the extension shaft and multiple holes in the extension shaft allow for a multitude of auger heights.
