Bit Choice for Drilling 2-Inch Holes in White Oak
From the original questioner:
Thanks for replying. I looked for 2" flat bits and couldn't find any locally. Do you know where I could order some from? I was about to order a Bormax forstner bit. They are made in Germany and are supposed to be very sharp and long lasting. They cost about $85. I found them at Traditional Woodworker's website.

What about making a template and using a router with a collar on it? You can get an upcut bit to remove the waste as you go.
From contributor P:
So if I read this right, quantity 116 with two inch diameter holes, five inches deep in white oak. That is a lot of work. Assuming your drill press has five inches of travel and sufficient power, I would go with a inserted spade drill and arbor. Not the woodworking style, but for metal working. It requires that you drill a 3/4 pilot hole first with a twist drill. Then pilot the spade drill through. Itís low on power requirements and does a slick job.
From contributor R:
I would use a Forstner. Standard steel would work well and can be easily sharpened or you can get carbide if you prefer, most of this size have a toothed rim and are fairly aggressive. You will definitely want to use a press and with a backup piece underneath you will get a clean exit.
From contributor L:
A multi-spur bit will drill those all day with no problem. I only use Forstner bits for specific applications such as flat bottomed holes, etc. Lee Valley Toothed Forstners are darn close to a multi-spur bit and priced affordable. For multi-spur bits see Fuller, Morris, Mcmaster. They are pricey but the best choice. We used them in the production shops on a daily basis.
