You know.......that piece may very well be just case hardened which most likely is in the mid 50's. Once you get through the .020"-.030" deep case, it will be as soft as the base material.
A lot depends on the base material as to what method and how hard it was heat treated. If it was through hardened, you're in for a battle without the proper mills.
If there's a spot on there you can run a small carbide drill into, you would see a change in the chips once it breaks through the case. If that is the case (no pun intended) you should have no problem doing what you want to provided you have a decent enough end mill to remove the case hardened areas.
Just a thought......
