I have drilled a few hundred holes in semi frames mounting axles/equipment and I can't imagine using battery tools!
We used a 1/2" drill with a "D" handle AND put a chain around the frame through the "D" in a loupe. With chain tight you rotate the drill which forces the drill into the hole.
In your case you might try a rope around the frame and drill to get more force.
You also must use slow speed with lub.
I've done a few holes in frames also. Had to get an electric 1/2" chuck drill with a side handle (not a "D" handle, but similar concept), plus the correct bits and lube. The electric drill with the right bits really makes all the difference. I don't think there are too many battery powered tools that will do what you are trying to do.
