This was my first time using a tap.. I could tell after the first 4 the metal seemed to be getting hotter and tougher... then snap!

If you are making new threads HSS is the way to go - those carbon steel taps they sell at the hardware store aren't good for much beyond cleaning up existing threads. Cutting oil helps a lot too - WD40 is good for aluminum, for steel I use "pipe threading oil", the heavy dark brown smelly stuff. That's a pretty multipurpose cutting oil. If you are going to do lots of tapping, there's stuff made especially for that purpose - "Tapmagic" I think is one name that comes to mind. If you are tapping a hole that you can't get to the other side of, giving the tap a heavy coat of grease helps hold on to the chips so they don't fall inside somewhere you can't access to clean.
Hope this helps! Eric
