Hole chamfer
Hole chamfer
(OP)
I have a .065 diameter hole going through a thickness of .25. I need to feed wires through this hole, so I was going to call out a chamfer, but how machinable is it to chamfer such a small hole? I could put an edge break note if it is not feasable to call out a chamfer.

Consider specifying a 120 degree chamfer with a tolerance of plus/minus ten degrees. This allows the fabricator to chamfer it with a slightly larger drill. It does not sound like you need accuracy.
