I've lately been buying tools made by Accusize because I've found them to be inexpensive yet good working tools, and I have no complaints about their center drill set. I also have an Accusize 3/4" roughing end mill that was inexpensive and it's been worth its' weight in gold. I've hogged out a lot of material with it and it's still good to go, as well as an 1½" carbide facing end mill that leaves a nice surface.
