SpeedOut 1000366 Cobalt Damaged Screw Extractor Kit, 4 Piece Set

I had absolutely zero faith that this would work, but it did.Made the mistake of overtightening and shearing off the end of a large bolt on some very expensive equipment which was a disaster. Thought I'd give this a try just in case.Drilled a small pilot hole into the bolt first to speed up the process. Then followed the instructions and gently reversed the screw out. Couldn't believe it actually worked, a relieved man! Picture shows the extracted bolt - the bolt end was originally flat from where it sheared and inside the device.

Read the instructions ,watched a u tube video , it did not work l would give this item a miss and save your money

It did nothing to the screw

My screw was completely stripped, and this kit removed the screw! It took me several attempts so don’t give up too soon

Well, I followed the directions to the letter and the bolts no closer to being out. The bit is not looking good and I’m thinking about getting my Drexel tool out to cut a slot! To sum up, not a great product. Wish I could rate it higher but it just didn’t work for me.

The bit got damaged when I tried to unscrew the normal non-tempered screw with low speed and not much initial torque. The metal is extremely soft, so it's definitely not a cobalt alloy as it's written in description, it's even not a tempered steel or HSS, more likely it's very soft and cheap alloy.

They don't extract screws. Other than that, awesome.

Wollte eine Schraube rausholen, da meine Bits nicht mehr fassen konnten. Habe wie auf der Anleitung beschrieben versucht die raus zu holen. Die Schraube ist noch drin und die billig Bits gingen kaputt. Das Material ist viel zu weich und hat sich innerhalb von Sekunden stark abgenutzt.
