Phil's Tank... and drill bits [TANKS]

After a busy weekend it begins to look like a tank....

..But sadly this is more form than substance:

This "clamshell" design is how the tank will open for maintenance. The motors and batteries go in the bottom, the marker in the top. Possibly.

A question for your assembled minds: my track system (of which more later) requires me to drill a 2mm hole through a 6mm bolt. This is possible- but I have broken drill bits which get very hot. The question is, what's the best way of drilling metal? Should I drill slowly, or with little pressure, so the bit doesn't get hot? Trickle water over the work? Let it get hot,then douse the work/drill in water?

Sorry if this is obvious, but I'm learning woodwork/metalwork and electronics as I go and all help appreciated!
