Good info.  I've had my bits loosen up and fall out while using them.

It doesn’t work on either my Mikita or Festool drills

There's a follow up video.

in which he's admitted to mistakenly spreading misinformation.

After conducting lots of research he was able to get the facts right.

 

 

On my Bosch there is no click-click-click and no big click.

But it just works.

Does not work on my Black and Decker, but it is 40 years old, which Chinese drills will never see.

The Festool drill tightens to the maximum by holding the barrel as I spin the chuck and doesn’t tighten further with the chuck stationary. The Mikita however will tighten further with the chuck stationary. It is quite possible that Festool may actually be making their own, it is virtually certain that they make the CENTROTEC chuck (which isn’t really a chuck at all but a shaft retention device) however the keyless chuck could possibly be a custom Röhm (Reohm) chuck, though it doesn’t have the locking system from the Röhm video so probably not one of theirs.

Here is the proof talked about in the video above. As an additional bonus we have the fabulous magic smoke definitely being released. ????
