They make a tool called turbo socket that has a reverse cut in it. The tighter it gets, the more it grabs. Or maybe the next smaller socket size can be tapped over the rounded portion and allow you to remove it. The following link has the sockets individually. Parts houses may loan you one also. Check the 4th one down.
