Oh! I just remembered something important: Not all end mills can be
plunged into the work. Those that can are called "center cutting".
Be sure to look closely at the end before buying a whole bunch of
them. Generally, 2 flute EMs will be center cutting.

Wouldn't there have to be some sort of cutter over the end?

The ones I've seen that weren't center cutting (and this by far does not
represent any meaningful percentage of the ones out there) were sharp on
the ends to the point where the 4 flutes came together. At that point, it
wasn't sharp. Those EMs could be ramped down into the work, but couldn't
be plunged.
