In the book Machine Shop Trade Secrets: A Guide to Manufacturing Machine Shop Practices by James A Harvey, he talks about using a type of quick change drill chuck.

He mentions that drillc can be changed in the chuck while the spindle is turning under power.

I have never seen a chuck like this and don't know how it would work or to describe it. Doing a google search for "quick change drill chucks" I have only found the keyless type where you have to stop the spindle and twist it with your hand like the chuck on a cordless drill/driver.

What kind of chuck is this guy talking about?
 
I got one at work. Never use it. You grab the chuck while spinning and either move the collar up or down to loosen or tighten. You are holding the drill in the other hand (lightly) when inserting or just catch it as it drops out when you loosen. I think it's too dangerous for my blood. Remember the bit begins turning at full speed as soon as you tighten, and especially with smaller bits, it's easy to get one set between the jaws, then it gets real interesting. My boss, as most, is all about speed, but he hates workmans comp claims. When he saw just how easily things can go bad wrong with that thing, he said "shelve it !!".
 
I used one at the job for multiple drilling reaming tapping operations. They work great if you have to change the tooling often. I do not have one now though as I find it easy enough to just stop and use the hand tightening chuck to change out the tool. I would recommend getting a better chuck which ever you choose. The hand tightening chucks, get a Rohm or Albright. They will hold up better and will be worth the extra in the long run. Setting up shop seems to be a never ending process. Been doing it for almost 20 years now and still have things I would like to get.

Oh, I don't want to change bits while spinning. I included that in the description to help jog people's memory.

Although, at $320 to $430, I'll probably be holding off for quite a while even if I decide I want one.
