Too much feed pressure. When you're almost

If he's drilling #304, that's an invitation to smoke the bit -- without
breaking it. As soon as it starts to "skate" under light pressure, it'll
work-harden the metal, dull the cutter, and end up making lots of smoke
and noise; and go nowhere.

And it likely will ruin the hole so you can't get anything else through
it except carbide.
