I have successfully extracted a helicoil that has stood proud like Peter's by using a small screwdriver to tease the free end up and then unwind it with a pair of sidecutters to grip it. According to the instructions that came with my kit, one is supposed to wind the insert in until it is one turn recessed into the hole. On the one occasion that I have had to extract it, the tang fell off before I could do this!
