I have no trouble getting studs out. Very important to drill in center of stud. If it goes off center you are screwed. head will be junk. I use dremel to grind small spot first. then use 1/8th bit. they are black bits that come on red cards. milwalkee or still cant remember. then use the square shaped easy outs.
