   I have a very large (12" diam) ceramic insulator which I wanted to use 
for coil top. My solution was to go to a nearby tile and marble cutting 
outfit and have them drill it for me. Since it was an expensive and fairly 
rare-size item, IMO it was well worth the $35 charge The diamond-dust coated 
Dremel bits would have cost me almost as much, and if I broke it, tuff stuff 
(They would pay to replace it if they broke it) . If you just gotta do it 
yourself, use new, sharp bits, go VERY slowly and don't try to drill the 
finished size to start with, use incremental bit sizes.
