Makes sense to keep speed and pressure low and lots of water.

Dale, I've never used a diamond drill. I have used a diamond 10 inch saw to cut rock, and it holds up well,
I learned when drilling pots, that the easiest way to keep water on the work is to set the pot in a tub with water just covering the area to be drilled. The pot will stay cool and lubricated. .
Re. concrete, I think it's best drilled using a carbide tooth core drill in a rotohammer. Maybe a diamond drill is too fine to cut effectivly in concrete which is softer than high fired ceramic. Just a guess.
