My calipers broke on me... I need the diameter of the Darkside's through holes so that I can do some really fancy socketing work. Thanks.
The drills are 1mm, IIRC.
A standard diameter socket fits perfectly. I think 24 ga. wire fits without trouble, but I think all of my stock is 22 ga., so I use a small drill but (I forget the number) on 'Bean's boards to accommodate my fat wires.
