I thought the WD-40 on a drill bit trick was just a myth

Tried it last week when drilling into some old, hard steel and it cut through like butter where it was just squealing before. Anyone have a go-to for when you're out of cutting oil?

Wait, you drilled steel without oil before?

Just a bit, it's not ideal.
