Any tricks to removing a stuck/stubborn/rusted-in place bleeder?

I've used these on misc applications, either drill existing/broken bleeder down to fluid, "pipe" tap threads into that, or sometimes I'll drill somewhere elsewhere at the top for ease of bleeding.
The bleeder screw fits into the brass fitting.
They work really well, come in a few sizes to suit.
Good luck
