I have a DRO. The issue is, if I move to point (1.2345, 6.5432), and
plung the drill down, will the hole really be in thast point or
somewhere close due to drill wandering.


The hole will be at that point it you use a suitable center or spotting
drill (short and stiff), and plunge fast enough that it bites properly
before having and opportunity to wander. You should also be using a
fairly high spindle speed for the small drills.
