I met a guy who had the nimrod adapter with a 18 volt drill mounted on his 6" auger, he let me borrow it and & I drilled 6 holes thru 16" of ice in no time, really impressive, think I'm going to get that set up next ice season. Just wondering what you all think is the best adapter, also the best drill for the money and would you prefer the 18 or 20 volt and does torque lbs. rating matter?
