I'd put penetrating oil in it and tap the chuck with a plastic hammer. That should free it up.

Ok, first check to see if the trigger lockout has been engaged, it's a small level at the top of the trigger ( I know this sounds silly, but it happens sometimes). Flip it side to side to see if you can hear the selector moving the switch inside the drill. If the selector moves freely without engaging the switch, you'll have to disassembly the drill housing to put the selector back into the lever so it will work.

Just take out all the screws in the housing and carefully remove the one side and look at the switch lever and make sure it is inside the slide selector lever.

If that isn't the issue, I'm afraid that the electric trigger/switch has failed and this isn't a part that can be disassembled and repaired by a DIY'er. I've attempted it when mine failed and found out it's a sealed unit and wrapped in a copper heat shield that dissapates heat when the variable speed is utilized and you end up destroying the switch housing in the process.

However, any DeWalt authorized repair center can do the repair for around $20 +/-, and if your drill is under the 3 year warranty period, it should be a free, warranty repair. Just contact DeWalt's customer service or your local Authorized Service Center (listed in phone book usually), or check the link for finding one near you.

www.dewalt.com or call 1-800-4-DEWALT (1-800-433-9258

Click on the "Services/Support" tab to get info. You can also buy the replacement parts if your drill is out of warranty (call them to verify before takin it apart!) and do the repair yourself.

Hope you find this Very Helpful and best regards!

SOURCE: Black and Decker corded drill won't tighten around a bit.

the chuck sounds like it is bad or maybe stuck from rust, what you can try and do is spray some WD-40 on the jaws and then try and holding the collar with a glove and run the drill SLOWLY in forward/reverse and see if it loosens up if not you will need a new one.

SOURCE: No reverse on drill.

I am assuming the new switch was wired correctly, I would look for the pin or similar device that switches it from for/rev. If your switch has a post look at the slider and make sure not broke or your pin not put in rightt position. Let me know
