Think about this before you spend time and $$ on this project.
If a 115V drill pulls 6A, then your 18V drill will pull about 38A
for the same power levels. This will take at least 6ga wire to connect
your power supply to the drill. Do you want to deal with the weight
and inflexibility of this cable?


And yet a 3.5 amp battery is all that is need to power the 18 volt drill.
The 18 bolt drill does not pull very many amps at all. 18 volt drills
motors so not deliver near the power of the corded 115 volt model drills.
The 18 volt drill can deliver close to the same torque by gear reduction at
the sacrifice of chuck RPM's.
