I used to hate keyless chucks,, the threads that closed the chuck were not fine enough, the chuck would barely tighten,,
I had a first generation Milwaukee 18 volt drill, there was no way to get that chuck to grip a drill bit.
Over 1/4" drill bit,, drill REAL slow, or the bit would spin.
Then,, I purchased a Milwaukee drill (a 18 volt battery) with keyless chuck about 2 years ago.
That drill will tighten so tight, you can not make a 1/2" drill slip in that chuck drilling steel.
It will literally tighten, by hand, so tight, that I have never owned a keyed chuck that would tighten as tight.
So, what I am alluding to is that vintage, and manufacturer makes a WORLD of difference in how a chuck works.
