ALDEN4507P Grabit Micro Broken Bolt Extractor 4 Piece Kit - Small Bolt and Screw Remover - Ideal for PC and Mac Repair - Made in The USA

I was skeptical based on some of the reviews but like any tool, you have to know how to use it and sometimes how to prep for the work. I had to extract a roughly 5/64 screw that broke in a very expensive electronic device. I chose to use a 1/16 bit to start digging into the screw. Then I used the extractor side to carefully work out the stuck bolt. Patience and precision are key. It’s not a high speed tool. Take your time and they work perfect.

These saved me hundreds of dollars. I made a mistake, and red loctited some very small set screws into a *very* expensive piece of equipment. When I went to change the component, the T10 head completely stripped, yes, I applied the proper amount of heat to loosen the loctite. These were easy to use, and after drilling, heated up the parts, very carefully and slowly reversed the bits into the drill holes, and the screws came out. Not sure how much more of a positive review I can write for them. Well worth it. Especially the smallest bit, which perfectly suited the small set screws I was removing. The bit was very sharp, and took good cuts with minimal down pressure.

I was not very confidant that these bits would remove the tiny stripped out screws in my Weihrauch air pistol but they worked perfectly. Saved me having to send it in or take to a gunsmith. I keep the tool in with some spare screws in my parts kit for the next time i strip these screws out.

Updated again - I never received the promised replacement bit. So have to go with my original assessment. The bit broke while attempting to extract a very soft screw. I can't recommend the product. While I was initially impressed with their quick reply and willingness to replace the broken bit, that was a month ago and the replacement has not arrived.Updated Review: The seller replied very quickly and is sending a replacement for the broken bit. Based on that and success using the other bits on a different screw, I'm upgrading to 4 stars for the quick customer service and the fact the bit worked on another screw without issue.Tried to use it to remove a pickguard screw on a guitar. These are not hard metal, not stainless, they strip very easily. In this case though, the cutting end of the smallest bit broke very quickly and without actually accomplishing the task. I understand that stuff like that happens, so may adjust this pending the sellers response. Also - the tip shearing off like that result in the guitar being damaged - fortunately, the damaged area is under the pickguard as it skipped off to the side of the screw in that direction instead of out into the visible part of the guitar, otherwise I'd be even more furious.

I had to remove a stripped 3mm from an optic mount on a slide. This was my last hope to remove the screw. I used the smallest bit. The drill end was not very effective. After many attempts and several minutes, it did not make much of a dent in making a hole for the extractor to be inserted. I had to use a DeWalt drill bit to make a hole which only took a 5-10 seconds. Once I inserted the extractor end and hit reverse on my drill, the screw came out without much effort. That saved the day. So an A+ for the extractor end but a fail for the drill end. Overall four stars since this saved me a lot of money by being able to do the job myself. Although this cost me around $39, I think it potentially saved me a couple hundred dollars in time, shipping, and third party labor if I had to send this out to get fixed.

Used the 3mm size to remove a screw with a detached head from a G45 MOS slide. I reviewed the instructions and consulted YT and some forums for additional information. I was overly cautious at first and kept trying to use the extraction end before the hole in the screw was deep enough for the extractor to take hold. Anyone saying that the drill end of these do not work is incorrect. You have to make sure you are using the the drill in the reverse (counterclockwise) setting for BOTH the drilling and the extraction.My client's options were very limited as the screw was only about 1 - 1.5 mm proud of the slide, had consulted with some expert pistol-smiths and confirmed there were very few options, the suggestions of course, flooded in, cut a slot in the screw and use a regular screwdriver (not enough meat on the screw shaft/not enough room; solder something to it and use that to unscrew it (maybe, but that would have to be an amazing solder job) Or get this device and in 20 minutes (should have been about 7, overly cautious) and the screw was out, no marring on the slide, no damage to the internal threads! Excellent bit of kit, won't use it often, but when you need it, you NEED it.

These things rock. Not only did I buy these to extract a stripped screw on an electronic device, I bought the bigger version to fix some more screws I found around the house. Highly highly recommend!
