I have a 1/2" dovetail bit in my (new) set. One of 26. It is 1/2" Dia. at
the very fat end. The actual end. It has a perpendicular cutting depth of
1/2". Nearest the shaft it is about 1/4" Dia.

If you wanted a groove, you get one cut, because you can't adjust the depth
of cut.

Is that what this is for?

So put the groove in the back of the face. Easy way to cover the glides
too. I may even try to even the sides now.

How do I do this? more.
