what is your favourite power tool for the job

mine is the hilti 36 volt battery drill for wall plugs raw bolt etc

bosch 10.8 volt for everything else including tightening circuit breakers screws you name it

14 volt hilti battey macnime for holesaws etc ...and when working isolated location where there is no power the 36 volt hilti always comes to the rescue by just changing the chuck over to use for holes saws etc
