Just go to McMaster.com and you'll see that you can spend up over $70
for a high end metal cutting 1" bit. So, drilling out the interior
rounded corner is an option.

Keep in mind that a 1" radius corner needs a 2" bit.

Then I
went into their aisle which contains birch plywood. Man that stuff was
warped!! Anybody know where to get quality 3/8" thick birch plywood?
This is for a homebrew computer controlled engraving machine, so warped
won't work. So far it's in the "gather the materials" phase. See
www.hobbycnc.com for more info if you'd like.

HD is a crap shoot on the quality. I hot a beautiful piece last week, but
I've walked away empty a few times. For your needs maybe a Baltic birch
ply would be better. Try a wood dealer rather than the big box stores.
