The PCB fab you chose will have a list of standard drill diameters, which the drill tool can pick at any time. Other diameters will require manual intervention, and you'll pay extra for that. I often use a 0.35 mm hole with a 0.7 mm diameter annular ring.

If your drawing calls out +/- mil tolerances for PTH's and via's, your PCB fab can select appropriate hole sizes that match their standard without upcharging for custom hole sizes.
