I believe the tool is hardened steel. The thing about it is that the reverse threads on the outer collar are very shallow. I presume that if the stud isn't going to budge, the collar will loose it's bite before breaking off. It was worth a shot and I guess I was lucky from what I heard. I bought the set knowing it would either work like magic or cause a giant catastrophe. I was most impressed that it worked on one stud that had been broken off for years and covered with exhaust soot. Again, I had the motor out of the car and drained of all fluids so I just tipped it on it's side to get a direct line with the drill. With the motor in the car, your mileage may vary. > > > ??
