Loboo IdeaDamaged Screw Extractor Tool Kit, Easy Out Screw Extractor Drill Bits Tool Set, Broken Bolt Stripped Screw Extractors with Any Drill, Broken Bolt Remover Set (11 Pieces Screw Extractor)

Very poor quality, each drill bit only stayed sharp for one drill hole and then the stud extractor snapped before the stud was released. I only have the 2 largest left which have not been used but I’m not holding much hope going on the smallest 3 bits.

After drilling into the bolt I tried the appropriate size extractor from the kit and....it actually made the situation worse by snapping inside the drilled hole. I did not use excessive force, the snap came easier than opening can of pepsi. Don't buy this kit.

Drill bits were no way near sharp enough to drill into the metal stud. Had to use a bit from my own stock. The extractor bit then sheered off as I tightened it (by hand) making the problem 10 times worse. Waste of money.

I had been struggling to get allen key bolts out of 4 alloy wheels and once I drilled them through, these made the job simple to get them out, all 120 of them!

Drill bits rubbish handle no strong enough to hold the bits , absolute junkDo not buy

I was sceptical as to how well these would work, but needed to remove sheared bolts from aluminium engine block. You need to make sure the centre hole really is drilled in the centre of the stud, and give the remover a bit of a tap with a hammer to get initial purchase, but then they did the trick. Bolts removed with no thread damage! Brilliant.

Brilliant

Snapped 2 of the drill bits couldn't even make the pilot hole
