This.
But for a banner i'd recommend brass rod so it looks a bit more banner pole'y and is potentially stronger. Or (I'm not sure how long the poles are) you could grab a wider drill bit and literally use the banner pole itself as the pin (so your basically deepening the space where the poles are supposed to go) 2-3
mm should be enough.
