Review on ABN Professional Thread Repair Kit by Johnny Spencer

If that sounds too good to be true. I was hoping that I would only have to use this set twice for two different sizes and it would pay off compared to buying spiral coils and I would have several other sizes if I needed them in the future. Unfortunately, the taps I received are so poorly made that they simply tear the material and do not cut threads. I hope they didn't damage the hole to the point where I can't salvage it with a real spiral coil.
