Drilling 750 holes!

I need opinions on the best type of drill bit to drill around 800 holes in fresh logs 1 inch deep and 7/16"/22mm. I need/want an adjustable mechanical means (like a bit stop) to go the 1". I don't want to bother looking at a visual means of going that depth.
I have 1/4 and 1/2 inch drills, Marketa.

Brad point bit and a stop collar. A number of companies make them. The brad point works better in soft/wet wood than a regular metal type drill point and produces a cleaner hole.Brad point bit and a stop collar. A number of companies make them.

Thanks for the reply. I know I don't want to use a regular metal bit. The holes would be much to ragged. I am worried about the brad point holding up to drilling 800 holes as fast as I can drill them. I was considering the auger type, but how do you put a stop on it, and will it hold up? What do you think?
The holes must be drilled as clean and consistent as I can get them

A forstner bit will give you the cleanest hole possible. You'll just have to use the tape on the bit method and eyeball the depth since the shaft is smaller than the head.

Speedy I sent this problem to a drill bit company. It's what they do so I figure I'll let them tell us! Will let you know.
