Wow. Someone is not having a good day. And typing at the top of his lungs, too!
Anyway, I agree with Randy and highspeedmazak on the tooling, but I grind flats on my carbide mills and use the set screw holders. The TTS tool holders do save you a lot of time. I don't use 1/2" very often at all. More because I have it in a HSS set than that I need it (except for when I need the length).
I am discovering that I like corner radius mills the best, because you get the flat bottom like an endmill plus the rounded edge like a ball mill. The cut loading is not nearly as high as with the square corner, and you don't have to change tools as often if you choose wisely. They do cost more than a flat end mill, but not more than a flat plus a ball mill.
