Will cold finished rounds always have a chamfered end for automatic bar feeders?

What would be some reasons to not choose cold finished bars?
If you are bending material, you must be aware that the process to create cold drawn bars creates a temper on all outside edges. This temper could cause the bars to crack when bending. Cold finished bars are also oiled after production to inhibit rust. If you wish to paint or prime the material, the oil must be cleaned off.
