25Pcs-Double Head Screw Extractor Set, Newest Version 3/8” Drive 2-in-1 Functional Easy Out Bolt Extractor Set, Premium CR-MO Steel Rounded Bolt Remover

Successfully removed two snapped locking wheel bolts from a Proace Verso (Peugeot/Citroen style locking bolts). Used the 3/8" with a hole drilled in each using a 10mm cobalt drill bit. The locking bolts had been over torqued and with the cold weather it looks like the tapered part had seized solid. Heated the head of the bolt with hot air gun at 500c for 5 mins each. Also used a torque wrench to remove so I could avoid snapping the extractor. The front wheel required 130nm of torque to remove (tightening spec for these is 100nm). I used a 16mm deep socket (not a 3/8" in square drive) as this gives a stronger interface around the extractor. If you are methodical and take your time and don't rush, these are extremely durable and will get you out of a fix. People who have left bad reviews seem to have issue with the smaller (weaker) extractors in the set - just needs some common sense and research to get excellent results. Saved me £80 in getting a specialist to do the job at least.

Excellent tool kit that works well. I use these on a daily basis, the quality is very good and the set is a comprehensive collection of most sizes of damaged threads you’ll find on automotive applications. I use these tools on a daily basis, don’t need imperial size drill bits has some have said, just use the equivalent or closest match metric drill. They fit all threads not just imperial threads! It’s the tool that removes the broken threads or seized bolts in the hole you’ve drilled, also you don’t need a left handed drill bit as I have seen in some reviews, made me laugh really. If you can’t remove the broken bolt or screw with this set you’re more than likely not using the tool correctly. All in all a good quality product at a reasonable price.

Good value for money and does the intended job

I would be inclined to use a socket over the hex rather than the half inch drive. Looks like they would be less likely to fracture.

Payed for itself in 20 seconds, well made but quite bulky so no suited to tight or narrow holes.

Might as well be made of butter. Had to return after first use.

Had a stubborn bolt to remove that my existing kit wouldn't do. This did the job well. Happy days.

Went they arrived I was immediately skeptical. The splines to bite into the screw were so smooth and shallow I didn't think they could grip anything. As expected, they didn't. In fact they just rounded the hole out further. Sent back for a refund. I only took a chance due to the convenience of quick delivery.

Works great. Had a Torx head screw on my mower engine that was seized and the head stripped. Cut a slit in it with a Dremel and tried to remove with a large flat head Craftsman screwdriver, and the screwdriver actually bent. I wanted an extractor that wouldn't break with such a stubborn screw, and after researching reviews on line, this Topec set was the best all around for the money. This extractor set got the screw out with little effort, and saved me $200. So glad that I bought these as I'm sure that I will eventually have a need for them again.

Good. Up to expectation.

works as expected

First time using set, used the 7/32 extractor on a bolt and it broke right away with just a short handle ratchet. Afraid to use them again because they are even harder to drill out than the bolts are.

this brand beat out all the competition in project farms testing and has the amazing convenient 3/8 end so you can put a ratchet in it, or even possibly an impact
