I am thinking the switch or motor is bad, check the switch first. you can locate parts at Make a wiring diagram before removing anything, these parts are polarity sensitive.

When i plug in battery on my drill the battery starts to smoke

This means the battery is overheating due to a direct short. Look for a way that the battery terminals could be connected ie metal shavings, bent tabs or cracked frame. If you put an ohm meeter on the tools connections you should have resistance if not the tool is shot.
You can look up parts at dewalt's service site

I have an 18v dewalt cordless drill which I used regularly. In the middle of a project, I put in a newly charged battery and it immediately started to smoke from the battery case. I assumed that it was due...

check continuity across two pins on drill that get power from battery. If they are 'touching' or have continuity the drill is bad. It sounds like that is the case as two batteries did the same thing. Can you try the batteries in any other 18v dewalt tool? Borrow a friends if you don't have any other tools but see if batteries do the same.
Also, measure power of battery before you put it in and see how much the afterward you had it in for a second how much power it has. If it is shorted in the drill it will drain power. Sounds like a short inside drill. GL

Using drill battery started getting extremly hot/ removed and it continued to get hot and started smoking. Put second battery in drill and same thing happened again. Whats Up?

the drill apparently has created a short in the battery contacts. Look at the contacts and then the switch contacts, there might be a wire going to ground against the motor or the switch has shorted creating this problem.

When i use the drill it smokes real bad where the batt. connects

you have a short in your drill motor. I would not recommend using it as it is possible for the battery to explode.

DeWalt is probably the best made drill motor. I would look to sending it back to the factory for repairs. Run the internet for DeWalt and get a phone # to call them. You never know, this may be a problem the factory may fix for free.

Dewalt cordless drill

You have burned out the drill motor, it is shorted, the battery smoked due to a direct short, one thing I don't understand why the thermal limiter didn't trip in battery pack, I would contact manufacturer and try to get hem to buy you a new drill.
