Abstract

A flightless rock auger (10) is used for drilling postholes through rock with the use of hydraulic pressure and at slow revolution per minute and can function utilizing only the weight of the auger. The rock auger is used in combination with a conventional flighted auger used for drilling postholes in dirt and clay. Further, the rock auger (10) is designed for use with pressure drilling units (16) as well for cutting a circular hole through the rock and forming a plug which is to be lodged in the cavity of the rock auger cylinder (20) to be removed from the posthole. A portion of the cylindrical body (20) of the rock auger (10) can be removed to allow quick clearance of the plug.
