Jellas 22PCS Damaged Screw Extractor, Screw Remover with 64-65 HRC Hardness, Separate Burnishing and Magnetic Extension Bit Holder for Damaged Screws or Bolts 2-12mm SE22

Doing DIY on the car drunk 🥴, I managed to round off a star drive screw. Tried to fix it with a hammer 🔨 and screwdriver to only make matters worse 🙃.Purchased this kit, instructions was clear use correct drill size first then change to extraction bit, one squeeze of the trigger and out it came, saved me a fortune in a garage bill. No reason this wouldn't work for security screws the lot even if they are in solid

They work

they do work but 2 of them broke, to easily!

It was good value, as the quality is good, & is contained in a protective casing.

Bought this kit to extract a broken off screw from an Espresso Machine portafilter handle holder. Have a lot of experience with tools and DIY. Smallest drill bit broken off at first attempt. We then proceeded with the largest bit that could fit into the broken screw without risking to damage the actual Portafilter. The drilling went ok and the extractor bit went in as expected. The battery drill clutch though was preventing extraction so we attempted to use and hand driver, and guess what, the extraction bit snapped, right off, looking very brittle, but then, nothing now seems to drill into it, no other drill head from the same kit, not high quality metal drilling bits. Searching my problem I found out that it happens often with low quality extraction kit, and the solution is either a specific tool costing £98 or a carbide drill bit at the cost of £20-30 per size. My recommendation (and what I would have done if I had the chance again) would be to simply drill the screw with a standard metal drill bit and use a Threading Tap to re-thread the hole if needed. I have to know buy a brand new Portafilter at the cost of £50 because of the damage caused by this extraction tool.

Despite my skepticism, I purchased this against my better judgement.However, the micro screws were holding a harddrive and the caddy is impossible to replace.Using the adaptors I put it into my Makita cordless impact driver. 5 mins later, rounded screwheads out and the caddy completely reusable.Perfect.

Easy follow instructions, with plenty of choice for sizes!

I was hopeful this toolset would help, however it didnt - I am unable to confidently blame the tool as I think it is equally possible I just did not or could not use it properly.
