If I were to have metal parts made by a CNC shop, at the cheapest rate, what tolerance could I expect. For example, if my file calls for a 5mm hole, what would be acceptable 4.8 -5.2mm?? Again, I have no idea of what is typical.

If designing a hole, that is supposed to have a rod go thru it, but be held tightly, like a 8mm rod and a hole, If I call for my hole to be 8.1mm is that enough of a gap to fit or do I need more clearance.

If I have a 5mm screw, that I want to thread the hole for, should I spec the hole at 4.5mm and then tap it or spec it smaller or larger?
