Alden 4507P Grabit Micro Broken Bolt Extractor 4 Piece Kit - Small Bolt and Screw Remover - Ideal for PC and Mac Repair - Made in The USA

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 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.

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 got some thread wrapped around a part in my Pfaff 130. Machine was jammed, so ok take it apart EXCEPT one screw was petty stripped and being soft stripped more, I tried the rubber band, etc and no luck. Then stepped away for a year. Order smaller collets for Dremel to hold smaller drills and finally hit on the right search term to find these. The Dremel doesn’t have a reverse and the grabits close to too big, so I used the Dremel with a tiny bit to drill hole then took the Grabit drill side in hand drill and it caught and the screw came out. Totally worth it to me to save the treads on the machine and avoid a more complex teardown. I also mess with pc, games systems, etc so am sure I will used again. One thing I don’t like is the card in the storage box just has barcode on back instead of directions so I cut directions off packaging, storage box is cheap but at least it has one

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!

Very happy with my purchase. I repair vintage toys/electronics and it’s very clear, that most parents were using micro Phillips instead of a #0 or #1 Phillips bc the screws get pretty bad- as the fate of a valuable one rested in my hands, I scoured amazon for the right solution. These are the perfect size for smaller screws and are good quality (glad I didn’t go with the cheap ones). First time using this, I was super bummed that it didn’t even budge the sucker, but luckily I decided to try the extractor end a size up from the drill bit- it hasn’t failed me yet.Now they aren’t a magical solution, so you’ll still need to set yourself up for success by using a penetrating oil/lubricant like WD-40… just be aware that if you’re using it on a painted item (like I do sometimes), that the WD-40 will dissolve the paint so be careful to apply it precisely. And of course be sure your applying firm downward pressure and keeping your drill in reverse for the duration. Stripped screw removal is part science, part art form in my opinion. Every one is is a little different. But this has been a nice trump card for me so far after I’ve tried some less extreme options- at least for my application. Your mileage could vary depending on material or method, but seriously, use the next size up in extractor before throwing in the towel- makes the tool just a bit more effective.
