Old timer at the shop taught me a trick for tapping aluminum
He showed me to use a bit of WD-40 instead of cutting oil, and after 500 holes I've never had a tap break since - anyone else use something different for soft metals?

Wait, you're telling me WD-40 actually works better than cutting oil for aluminum?
