So with the ice thick as heck .... I decided to make an adaptor for my 6 inch hand auger . A piece of pipe inside , drilled hole for bolt , welded a 3/8 clue is pin on the end to attach to the drill ...... Tried it with my cheap craftsman 18 volt drill last week and it was a dud ! Brought home the 18 volt dewalt hammer drill . Went out to moggy and tried it again ..... 11 inches of ice ....... 7 seconds clean hole !!!! Need to pick up a dewalt !
