Metal should be drilled as slow as possible. As long as you see metal shavings. When you see long metal shavings you know you have found the right speed and pressure. Oil will also help.

Subject: 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!
