I'm using a Baum tool. This one is for 8mm and has a threaded collar w/ lock nut. I also have the cam style that you mention, John. It toasts threads in a second... DO NOT use it on your case studs unless you are replacing them all

At the time I tried to order the 10mm Baum as well, but the guy said they were out and stopped making them...
