Damaged Screw Remover and Extractor Set, YWKOW 11pcs/set Screw Extractor Drill Bits with Holding Wrench for Removal of Broken or Damaged Screws

Pretty cheap set here, you get what you pay for. Won't tighten good enough to hold the extractor but in place. If you're using this on soft wood maybe you'll be OK. Try to remove a broken bolt from anything else? Forget it.

Don’t wast your money. Damn thing broke the first time I used it I’m sending back when I get the time to get to the post office.

Poorly made for what I consider to be a high price. It snapped like a twig, wasn't even trying that hard.

Good to have.

Amazing. Worked like a charm
