Try a jeweler's saw--a much more precise tool than a coping saw although they look a lot a like. These saws are fairly inexpensive (student grade) and you can order blades you almost need a magnifying glass to see. You can get much crisper holes than a coping saw. Google jewelery supply companies for sources.
