Check out a Forstner bit. They are designed to do just what you describe.
It will leave a small dimple in the bottom center of the hole and, if that's
objectionable to you, you could grind off the centering nib from the bit.

They are readily available and most good hardware stores carry them
as does the woodworking stores such as Rockler and Woodcraft.

Am looking for a way to make a 1 1/2" dia. hole, ~1 1/2" deep with
minimal bottom indentation (flat-bottomed hole). I have a 1/2 hp drill
press and a 3/4 hp lathe.

38 mm is also acceptable.

I want to make the hole in one pass. This is not a critical appearance
item but, of course, better is better.

What is my best choice of drill bit and who, if you know, has them for
yesterday delivery?

Bill
