Suppose you have riveted two parts together so they are sitting flush and tight against each other. Suppose you wish to add a third rivet for added strength. So you drill a hole through the mated parts for the third rivet. You can deburr the sides of the hole on the outside faces of the parts, but obviously you can't deburr the hole on the inside faces, where the parts are mated together (or is there some way to do this?)
Is this a big deal, or do burrs not really form between the mated parts?
