DMAXO 05 Pcs Damaged Screw Extractor Set - Broken Screw Removal Tool – Damaged Screw Remover Set for Rounded Screw Heads - Stripped Screw Extractor Kit- High Speed Steel 4341 62-63 HRC

Purchased this item to remove a damaged hex (allen key) socket headed bolt from a rather expensive £2k rifle that I had been a bit heavy-handed with and rounded off the 2.5mm allen key socket while fitting an upgrade part to the cocking mechanism. Given the value of the item it was attached to, this was a bit of an anxious bit of work! As the damaged allen key socket was already big enough I didn't use the drill-end of the bit, but instead went straight for the smallest of the screw removing tools, turning it slowly counter-clockwise in a ratchet screwdriver handle rather than in a drill or electronic driver. With very little trouble the screw remover bit, and almost effortlessly turned the damaged bolt, removing it with ease. I'd got a replacement bolt in stock already, so completing the work was a simple case of fitting the replacement bolt - with a little more care!!! PERFECT RESULT! Easy 5 stars.Update: Don't you just LOVE IT when a tool you bought for one job comes to the rescue a 2nd time?! We have secondary locks fitted to our up-and-over garage doors at home, but I had reason to refit the bracket that is bolted to the garage floor, and sheared off the head of one of the M8 RawlBolts. The screw removing tools did the job again - this time fitted in a drill. I gradually worked my way up through the sizes, the 2nd biggest finally bit and extracted the sheared-off 60mm threaded portion of the sheared bolt. 2 great jobs handled well by this superb bit of kit. 100% satisfied. Twice!

I used this to remove three extremely corroded screws holding in place a fan oven heating element. The screws were at rather awkward angles, and had been in place for over 12 years. Having used the cutting head (with an 18V drill in reverse), I changed ends.The gripping end didn't budge the screws at all, and I was about to give up. However, on turning back to the cutting head I was able to drill out most of the metal on the screw heads, which were easy enough to work loose with pliers afterwards. This entailed about five minutes of drilling per screw and the cutting heads used are still sharp.I hadn't been able drill the offending screws out with regular HSS drill bits. Although the extraction tool didn't work exactly as expected, it got the job done. The original screw holes are still the same diameter. I will need to replace three small screws, but that's a lot less costly than buying a new oven.

I didn’t really think I’d have much success with this as the problem wasn’t that the screw head was damaged, I just couldn’t get it to turn, but thought I’d try it anyway. Trying to replace the lock on my front door.I did a few test screws where I tightened it too much till the screwdriver wouldn’t catch. And it worked great.1st attempt on the door didn’t work. So drilled it a bit more. Used the extractor end and it slid out. Amazed. Would highly recommend.For £8 it’s worth trying before calling someone out which would be drastically higher.

I bought these to remove three countersunk screws on the base of my push strimmer. These screws were seized and had resisted all prior attempts by me to get them out (heat, banging) and in my over-exuberance and perhaps a smidgen of frustration, I had turned the philips head profile into mush.In desperation I consulted YouTube for solutions and these came up (not this particular brand but this solution).Looking at the prior reviews, I knew they weren't the best quality but I thought for around six quid even if I get one go from them, I'd be happy.How did they perform? Ok, I guess. They managed to successfully remove two of the three screws outright. The third screw was so tight that all the extractors did was to essentially mill out the countersunk head to the point where only the screw shaft remained. In the end I also managed to get it out by backing out the screw shaft using a pinch. So you could say these extractors did help get that screw out too, but indirectly.By the end of all my excertions, the ends of the extractors were blunted so I'm not sure I will be able to use them again. That said, I only paid six quid for them and they got the job done.In fairness my use case was probably at the extreme end of testing with seized steel-on-steel countersunk screws with no means of backing them out because their heads were mush. I think these would probably work a lot better (and not be so damaged in the process) with less extreme situations eg wood screws.

I had a bad screw head that needed to get out. Bought this kit, and spent a good 30/45 minutes reading instructions, and watching videos on how to use them but it was totally useless.Unable to really grip the screw.The screw was only a few mm out and couldn't really make the drill chick grip to it either....Genius idea took out the dremel and used it to lime the screw head a bit until it became a bit squared. I then used to unscrew 1 or 2 more mm, just enough for the drill chuck to get a grip of it and I pulled it out that way.I've sent back this kit as it was useless.
