[Dull Knife]

For all/any of you who are using the small, three jaw chucks that you can get thru Micro Mark, on your Dremel tools. You need to check to see if the two halves of the chuck are tight together......I had one come apart a week ago while I was running my Dremel tool....needless to say it scared the stuffing outta me. Fortunately, I was not hit by any of the flying pieces. I found all three of the jaws, but, alas the tiny springs are gone.

Send it back explaining what happen. Maybe they have a whole line that way. Maybe get a new one in replacement.
