$begingroup$ @aaronfarr The easy way would be to start with an AC/DC power supply that has the correct voltage and current. Then, take a battery pack, remove the batteries, and either fit the power supply in it or use the battery pack as a sort of bulky adapter. In that way the drill would remain unmodified and hopefully wouldn''t kill the drill.
