I wouldn't try an ez out, too much risk of breaking it. I would rather center punch, use a small drill bit and go progressively larger. If it's done well enough, a tap can clean the threads, or if you get close to the end and think you may be off center, you can try welding a nut to it, the weld will partially fill the void and give a stronger purchase, plus since you've drilled the center it should make removing a little easier.Sent from my SM-S920L using Tapatalk
