Quite the collection Chuck!  Must be some deep visceral connection to buying tools with "chucks" 😀

It isn't often, but when you need a 1" chuck, you need it. Nice looking rehabs!

I have a "micro" chuck for the #60 drills, has a 3/8" straight shank which fits into all my other tools chucks. Lets me basically ignore the minimum size spec for the big boys.
