I concur of course. I just thought that you should have stressed that
point to the OP and advised him to look inside his drill's fully opened
chuck again.

And, most (maybe all) of those chuck screws I've encountered have left
hand threads, the OP might not think about it being left hand and bugger
up the screw trying to remove it "lefty loosey." (Now I've told him, if
he's reading this...)

Best Regards,

Jeff
