Tom,

You should be able to mill those. Mill as much of the pocket as you can with a larger end mill then pick the corners out with a smaller diameter, long end mill. I would recommend plunge cutting most of the material out before side milling to keep from breaking the long end mill. This is a good application for carbide because of it's rigidity but you would need to be careful because it's is also very brittle.

I would also suggest making the pins out of O1 so you can easily harden them.
