Interesting; never thought of that, but I'm looking for only about a
7/8" - 1" bowl or hollow.

7/8-1" in diameter. As a hemisphere, it would be 7/16 - 1/2" deep.

I have no idea what "DAGS" is or means.

You are kidding, no?

I don't use google. It's just not very good. Try Ask.com.

Thanks anyway.

I found core box router bits and plain round end router bits without
using any search tools.

Then IMO your best solution would be to use a router and core box bit;
alternatively, grind down a spade bit.

Depending on the size of the desired hollow, you can do so with a saw,
either radial or table, by turning the blade at an angle to the blade
path and taking very shallow (1/16) and repetitive cuts with just the
edge of the blade teeth. The size and angle of the blade determine
the radius.

(D)o (A) (G)oogle (S)earch- sorry about the acronym, I've seen it
enough to figure it was common parlance.

Deep or diameter?

DAGS for carving burrs. You should be able to get one the size you
need, and chuck it in a drill press.

So, for the fun of it, I did! This is what I learnt:

DAGS Data Architecture and Gateway Services
DAGS Demonstrator Application Grant Scheme
DAGS Diagnostic and AGreement Statistics
DAGS Dynamic Airspace Management System
DAGS Diacylglycerols

In that size range you may be able to grind a cheap spade bit to the
profile you need. Remove as much wood as possible first with a
forstner (or regular spade bit if the hole left by the pilot section
won't matter) This would definitely best be done in a drill press!
