How are the current drills handling cold weather? Will they work down to -30F if I keep the battery inside my jacket? Is battery life and performance greatly affected? Any brands better than others in the cold - Milwaukee, Dewalt, Ridgid?
I know from first hand experience Jiffy and Eskimo propane won't work below about -15F, even with the propane tank kept warm inside your jacket. I watched a SM 40 volt drill holes like a champ on a -27F morning this year so I know they are solid in the cold.
Just for some background, the few days I'll fish in this weather each year start with a 1 hour snowmobile ride. So keeping the whole drill warm isn't really an option. Only realistic option is to keep the batteries warm in my jacket.
