Thanks for the info. on Cleveland Crenwelge, I can handle the rusty stuff or bolts fine, I was looking at stripped screws like Phillips head product that my Pozidriv won't even grip. I wanted a quicker way to extract them than using vice grips. Got a little project I am going to start in a couple of weeks and I am sure to round off one or two with my drill and phillips bit. I want to be prepared and not play around with vice grips twisting the stripped screw out.
Btw...malox works like anti-seize on aluminum to keep them from galling if you have no anti-seize handy.
