I found the titanium step drill (item # 69088) from HF works pretty well for drilling frame rivets.
I think the first step size is 1/8 inch on the smaller step drill.

Must be something about the cutting surface angle versus a standard drill.
Difficult to break these as well.

An accurate center punch location is a given.
