I have had the issue with both Cura and Simplify3D.
For a circular hole, as far as I can tell the slicer commands the hotend path to trace the circle exactly, rather than tracing a slightly bigger circle to account for output thickness.
I imagine if you were to use smaller nozzles the issue would be lesser, but not gone.
