A hole for a wire through it?  No.

Drilling holes with EDM?   Straight plunge cut/burn.  Hole size determined by 
the electrode in this case.  Only milling machine motion if I get the right 
electrode size is z, at about .001" a minute, which emc can manage nicely.  I 
have everything but the right sized electrode on hand.  Even some trash that 
needs burnt by tossing the used kerosene on it. :)
