Jellas 22Pcs Damaged Screw Extractor Set, Easy Out Stripped Screw Remover for Broken Screw 2-12mm, Titanium Antirust Coating, 64-65 HRC Hardness, Burnish & Extract Bits Separatly

Without quite the right tools for the job it can be difficult to use this kit, but it definitely does the job. I had sheered off a nozzle in the hotend of my 3D printer, because of how the 3D printer's put together, it would've been harder for me to take it apart than try to remove the sheered nozzle. I had to switch between different bits in this kit until one finally bit into the material and allowed me to extract the part - a couple of the bits stripped the thread, then I finally got a lock and with effort, away it came! Which makes it worth it, as the 3D printer is now printing successfully. This isn't something I intend on doing regularly, but it'll definitely help when it does happen. What does make it tricky to use is the fact that it's a magnetic 'bit' that is very short, you can't 'pull' on the work at all to encourage the whole part you're trying to extract to come out, so you're relying heavily on the kit's ability to unscrew the stuck piece. Only really useful if you have a good grip or purchase on the thing which you're trying to remove the sheered bolt or screw from to prevent it from spinning and don't put too much pressure on it.

I had a cheaper set that was terrible. This one is far better. The bolt in the photo was really stripped being recessed I couldn't get any grip on it with pliers or any other terrible amateur method. These were cheap enough and could be delivered prime so thought I'd risk it. Fair enough, only one use so far. Took two attempts, should have used a slightly bigger one first off but never having done it before that seems fair enough. Had to grip the bolt with monkey wrench to get it off! Great though, it works with little fuss. Very good buy. One for any toolbox!

A nice little set of tools for a specific task of removing bolts. For the average removal I’m sure it will work well. I did break a bit on first use and failed to remove the broken stud but to be fair it was PROPPER STUCK 😳

Followed the instructions clearly, took care not to force anything (was extracting a bolt from a carbon fibre workpiece so I really took time over it) and the first time I put any rotational force through the extractor bit, it sheared and broke, leaving a piece of hardened steel in the hole. Since then I've had to buy a dremel, and have gone through more than fifty (50!) Diamond-tipped bits, and hours of my time trying to remove the piece of steel from the otherwise soft and vulnerable work piece. I'm considering contacting the manufacturer to claim for the cost of the piece, which is about £400 considering how unsuited to the task the hardware was, and the poor manufacturing/materials quality had ended up causing more issues and damage than just simply drilling out the offending aluminium screw would have done. Absolute bottom-tier garbage

Really good selection of sizes and very good quality. Worked a treat at removing a sheared head screw on a door hinge. My only complaint is that the supplied drill bits are a little short, particularly when the screw has sheared off part way down the screw shaft.

As my title says, this is fine for simple home diy type screws that might have stripped the thread or are just spinning around and you can't remove them. Beyond that for anything stronger they're absolutely useless and they'll break really easily. The hardness mentioned in the product description is pointless as a guide as to whether they'll do what you need it to as you'll unlikely find any reference as to what hardness the screw is that you're trying to get out! If it's not a basic aluminium screw then don't expect it to remove without breaking.

This works well for those times when you have over tightened a cr4ew with a power driver or drill so that you can;t use a screwdriver to undo it. I have used it with screws into wood that were rounded off, and it worked just fine, but when I tried it with a broken bolt on my Cross Trainer, it didn't;t, and didn't;t expect it to work, in fact in the end nothing worked! The bits have hardened tips, but they are not indestructible, which is why they supply some spares of the popular sizes. Just be careful, don't over drill anything, take your time and it will be fine. Make sure you drill in the middle of the screw, sounds easy, but it is important. All in all , a handy extra to have up your sleeve when a screw head has been destroyed.

Needed a micro screw extractor kit this did everything I wonted, very strong grip strength. Good quality.
