Pool Fence - Need to drill 1" holes or 1/2"

[gnr5]

So, didn't know how to title this thread.

Anyhow, I've been doing a lot of research into installing my own pool fence. Several companies out there selling fences such as Pool Fence DIY all call for 1/2" holes with a 5/8 drill. I've been digging on OfferUp for a used fence and all of them are 1" wide, meaning the holes has to be a 1 1/4".

Will a rotary hammer drill go through concrete at 1 1/4?
Am I missing something??

The 5/8 hole probably gets a plastic sleeve so that will reduce the final hole to 1/2". The other hole I have no idea.

The used ones I've seen have a one inch poles:
