Drill rod would be overkill and unecessarily expensive.
Cold rolled steel would be the material of choice here.

Ken: I think you may have missed an important feature of the drill
rod. Cold rolled and plated steel has a pretty broad diameter
tolerance and may be very difficult to fit into bearings. The drill
rod will be tighter tolerance but probably .001-.002 oversize. What
this fellow needs is a short piece of C1065 TPG (turned, polished &
ground) available from many metal supply houses. Very stuff, very
straight and right on the correct diameter. Leigh @ MarMachine

Listen to Leigh..he really really knows his ****.

He sure does.
I tend to be cheap and cold rolled has been good to me even onto fitting
bearings - but ,to be sure, precision shafting would be the best choice.
