How do I punch a small hole into a business card...

Okay, at first glance this is a dumb question but hear me out… I need to punch a nice clean hole into my business cards for this special business card holder I am making (I won’t go into the details). It is important that the hole is clean, so I can’t stick a pen through it. Also, a standard hole punch makes way too big of a hole, I need the hole to be about ¼ the size of a standard hole punch. Do they sell hole punches that make smaller size holes? I’ve never thought about this before and am stumped are there things out there for this?
