I bought one from Napa and it worked well and boring through the stud..
too well.  Zipped right into the aluminum before I knew it.

I managed not to break off any extractors in the process, that would
have been enough for me to truly loose it.

the tool I used is the same as the Facom I think.  It is a 4 piece set
sized specifically for each size stud.  As the tool rotates counter
clockwise it clamps down on the threads.  Works awesome, except when the
threads on the end are galled and things are just going to break no
matter what you do (like in my case).
