4507P Grabit Micro Broken Bolt Extractor 4 Piece Kit - Small Bolt and Screw Remover - Ideal for PC and Mac Repair - Made in The USA

If you have a old MacBook air mid 2012 . And the ssd original m.2 screw does not come out . This is the perfect tool for it especially small drill drill it first then extract the broken screw

I must say that I wasn't hopeful that this would work to extract a very small screw from the end of some cycle forks. The head had completely sheared off, leaving just the shaft, maybe 3mm across at best, and with a load of corrosion around the threaded plate it was stuck in. This was a last resort before shelling out £300 for replacement forks. However it works, and beautifully! The boring end seemed to just ignore the rough sheared face and seemed to find centre really easily, and then the screw in end managed to grip inside the hole, and unscrewed it beautifully. All with a piece of metal no more than 5mm by 3mm. Just take it REALLY slowly with the drill, be patient, and this will work. A cursory look at the bit head suggests that it hasn't sacrificed itself and will be good for many more applications. This isn't a cheap item, but in my case it's saved me over £250, so I'm very happy indeed.

Broke two of these on first use, have also used a Sealy kit which is cheaper and works. This is expensive and too weak
