Rule of thumb is 1% for hand reaming and 2% for machine reaming you can go more than this on larger reamers.

What is the difference between reaming and boring?

The main difference between drilling, boring and reaming is that drilling is when you make a brand new hole in your work piece. But boring is when you enlarge the hole. When you give a finishing touch to your hole that means you are reaming. The process of drilling uses a drill bit.
