I'm looking for endmills that are sort of shaped like a woodruff key
cutter. That is an endmill with a smaller shank than the cutting
edges. One with something like a 1/2 inch shank and a 3/4" diameter
cutter. is there a name for for this type of endmill? Know of a
source?

I need to cut shallow slots in a side wall of a big slot, if that
makes sense.

Sounds like you want a "T" slot cutter !
