Title: save your money
Review: have used these DeWalt chucks quite a bit in my line of work as a union tinner. had our tool crib send one out and it lasted two days before it crapped out on me. sent it back for a replacement and the same thing happened to the replacement, turns out one of the three jaws would get jammed and not align with the others when tightening. even when it was working, i found it to be a PITA to get a bit in and out of it. a coworker of mine has a unibit permanently locked in his, unable to get the bit out, he now has to deal with dead weight of a locked DeWalt chuck on his expensive unibit. for all the aggravation i'd much rather deal with a keyed chuck, or if you've got the coin, spring for the Hitachi chuck.
