The chuck will improve if it's reduced to its component parts,
deburred and lubricated. There's usually one jaw that binds against
the body, reducing the clamping force.
All that being said, drill rod is a real bear to get clean threads
on. Single point roughing followed by a die is a winning method,
enhanced with a thread file for final finish.

I tried to hold a piece of D size drill rod (.246") in the stad 3"
chuck on my Homier 7x12 and cut a 1/4-20 thread, and could not. The
rod would slip in the chuck, no matter how hard I tried to crack the
jaws closed. Is that as expected, or do I need to do something to my
chuck?
