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 for easier digging in hard soil. A single spring pin lock connects a first shaft to the extension shaft.
