Ok, I've got a DeWalt DW511 VSR Hammer Drill. I noticed that my chuck has been sort of sticky and such, and I oiled it up... but it doesn't seem to really hold the drill as well any more. It will hold it for about 20 seconds into drilling, and then it comes loose from the hammering.

I've had the drill about 2 years now, and I've drilled countless numbers of holes with it. I've used 1/4" to 1 1/2" masonry drills with it and had no problems going through poured concrete, cinderblocks, and brick.

Should I just buy a whole new drill, or can I buy a new chuck for it?

The drill works fine, it's just that it needs a new friggin' chuck.

Edit:

I was thinking of bringing it to a DeWalt Authorized Service Center and have them take a look at it... but if they tell me no go... should I get a drill from a different manufacturer? Like Porter Cable? If I got to get a new one, I'm going to step up a lot, just as a FYI. However, I'm a big DeWalt fan, and I've never had a single problem with any of my DeWalts.

 

Chucks are very easy to replace. Open it up all the way, look down inside, and you'll see the screw that holds it in place. Might be Phillips head, but probably is a hex key.

VERY IMPORTANT REMINDER: Due to the fact that it has to rotate, this screw will be reverse threaded: Righty loosey, lefty tighty.

Don't worry about going to an "Authorized Dewalt Service Center", it's most likely a Jacobs brand chuck, and you can get them at just about any good tool supply house, Sears, tool truck, whatever.

 

I just got it out of my truck, and I opened it up... sure enough, a Metric hex key....

Never even noticed it down there!!!
