• Beware! This accessory is hazardous!
  Several other reviewers have commented on the tendency of this keyless chuck to wobble and loosen in use. In some 20 years of use of this accessory, I've also found this to be the case (the tool bit works loose during use about 1/3 of the time), but have also found that this is particularly dangerous at high tool speeds. I recently had the keyless chuck vibrate loose while using a cut-off disk. Despite the fact that I felt a vibration in the tool and hurriedly moved to shut it down, by the time I did so,... more info

• a real time saver
  I have at least six dremels in constant use in my metal restoration shop. Using them to grind cut, smooth, polish and drill among other things.
  The collet system makes me nuts, so I use the chuck. It isn't perfect, and comes loose a lot, so I keep a pair of plyers handy so I can crank down on whatever tool I am using As long as the tight plyers are around, the chuck makes the dremel far more usable.

• Makes bit changes far more quick and easy
  This chuck makes changing bits on the Dremel very quick and easy. I always hated having to look around for that wrench thing to change a bit...and I misplaced it a few times too. This is pretty heavy duty and excellent quality. Great item.

• they got it right the second time
  In 1994 I purchased a Dremel kit and a version of this chuck was included. I was quite excited as those who have worked with the fixed-size collets know how pesky they are, especially for small drill bits.
  ohmi Vibration. I contacted Dremel Manufacturing and they, in 1995, had withdrawn this chuck as it was "too heavy" and "did not run true." They were glad to send me a package of fixed collets (but, having about fifteen different Dremels -- AC and battery), I have enough collets, thank you.more info
