This seems like a good place to ask this newbe question:

It you bore a hole with a 7/32" brad point bit, is it reasonable to
expect to be able to tap a 1/4" dowel into it? I have to assume this is
why they make 7/32". Is the dowel generally chosen to be of soft wood
to accommodate this?

Generally speaking you want to use a 1/4 inch bit for a 1/4 inch dowel
unless you are using some kind of proprietary system with special bits
and dowels.

7/32 would be the pilot drill for a #18 straight shank wood screw in
hardwood or the clearance drill for a McFeelys #12, among other uses.
