In a case like this I would click on the view and hit S to start a new sketch and sketch the needed geometry.
The problem is that hole edge creates a spline rather than a circle.

In certain cases - you might be able to add some tiny geometry to the model to fudge what you need - but this might cause problems if go all digital from CAD to CAM.  (add a tiny revolve cut at the center line - fudge to give a circle)
