[Shop-talk] drill chuck keys

[john niolon]

ok... everyone but me probably knows the answer to this question so I'll 
show how dumb I am and ask...

how do you fid the size of drill chuck keys ???  I've seen reference to 
pilot hole size and seen keys that are #1 or #4...but what does that mean... 
do all drill chucks with a 1/4" pilot hole have the same number of teeth ?? 
or does it differ by manufacturer...

I've got a drill press at work that is missing a key... the numbers/words on 
the chuck have been obliterated and I'd like to find a key to fit it...

help educate the dummy please ???

thanks
John
