5 Pcs Screw Extractor Set, Hex Shank Damaged Broken Bolt Stud Remover, HSS High Speed Steel Easy Out Drill Bits Kit, Fine Teeth

Absolutely rubbish don’t buy these. Snapped off in the hole I have drilled first attempt . Now I have to drill this out. Just unbelievable don’t waste your money, time and also the part you need.

I tried - unsuccessfully - to use them to extract a broken bolt after I had successfully drilled a hole down its centre. The thread of the reverse screw on the extractor should have bitten into the metal edge of the hole in the bolt. Instead the metal edge of the hole in the bolt removed the thread from the extractor, leaving the broken bolt unmoved. I will need to find an extractor set that has not been (badly) made in China.

Used them today and removed screws no both

First turn into a broken 5mm mild steel bolt and the product snapped off in the drilled hole. Absolute rubbish. Now I'm left with a harder steel insert to drill out. Had my drill on minimum torque which I can hold still with my hand. Terrible product!
