The reply from whit is a good suggestion, but I suspect that the cells in
the drill are shorted, which will damage a charging power supply. It seems
that the old supply became overheated and failed, which will happen if the
cells are shorted.
I believe this is the reason for the substitute wall wart getting hot.

To find out if the cells are shorted, the cells need to be accessed, and
individually checked with an ohm meter or an instrument capable of measuring
battery cell impedance or ESR.
Also, a reading for individual cells with voltmeter reading of zero volts
generally indicates shorted cells.

Replacing all of the cells is the most effective solution, and cells with
tabs can be soldered together in the original order, and restore full (or
even better) operation of the drill (or most cordless tools).

If you have the ability to make good solder connections, replacement is
usually less costly than paying someone else to do the work.

There are numerous online sellers with reasonable prices for replacement
cells.

NOPE, IF the host picks the remaining door he now has a 1/3 chance of the
big prize, and the other two also have only a 1/3 chance each of the big
prize, NOT 50:50.

I should have added that yes IF (and only IF) the host reveals a goat, the
other two will now have a 50:50 chance, but surely that is obvious, and
remains so whether they both switch or both stay, so is NO Longer like the
original MH problem at all.
