Abstract:
Taught is an auger having a working head (), a ratcheting T-handle (), and a shaft () attached there between forming a hand-powered ratcheting auger for drilling holes near the ground surface. Shaft () may include one or more lengths of extension shaft parts to control the length of the shaft. Working head () contains a drill-bit (), semi-circular non-planar cutting blades (), a working head shaft part (), with the drill-bit and cutting blades fixedly attached to the working head shaft part and shaft part () detachably attached to shaft (). The auger may also include an air induction unit including an air-receiving opening in the T-shaped handle; an air-line positioned within a hollow of the shaft connecting the air-receiving opening with air exhaust openings so as a jet of the air can blow out of said auger to break up and blow away the drilling detritus.
