Is that the stuff RS sell - if so it is very expensive, although I know 
RS is not the cheapest place to get bits from, I rather suspect the cost 
will be far more than buying ceramic insulators. Of course, you can get 
what size you want, but if it is what I think it is, the cost is very 
high indeed.
