<<<You can usually turn with much more force
with a good vice grip compared to an easy out>>>>
In my early wrench turning days, I broke off an easy out I was using to extract
a broken off shock absorber mounting bolt on the axle beam of a '64 Bug. The
machine shop had to extract the easy out, and only after I removed delivered the
front end to their shop in our '68 Ranch Wagon (a Ford product).
