NEIKO 01925A Screw-Extractor And Left-Hand Drill-Bit Set, HSS M2 Steel Drill Bits, Alloy Spiral Flutes, Reverse Drill-Bit And Bolt Extractor, Easily Remove Stripped Screws And Broken Bolts, 10 Pieces

Broke an M6 bolt off in the block over torquing water inlet for the thermostat housing. Used this to back it out - only needed the reverse drill bit. The joy of seeing the bolt back out was indescribable, lol.

Works as described.

The reverse drill bits make all the difference and worked as expected. There are some possible quality control issues though. The first set I got was missing a bit and there was some slag fused to the larger extractor. Returned it and got a replacement that had no problems. The metal storage case is pretty cheaply made and required bending of some tabs to keep the smaller bits from sliding down and out of their spot.

Just like any spiral flute extractors they are not great but I have gotten bolts and screws out with them so I consider that a win. Drill bits are fine. Have broken most of the extractors at this point - 3 years since I bought them. But that is to be expected with spiral flute extractors.

...that they're crap. I used a punch to make an indent in the center of the broken bolt. I started with the small drill bit being careful after so many reports of it breaking. It did nothing but get dull and then it snapped in two. I went to the nest size up and same thing. I went to my tool chest and found a bit that would cut into the bolt. Time for the extractor. I couldn't get any of them to bite. The whole kit is apparently just for decoration. The nicest thing about the kit is the metal case, but even it has it's flaw. It's that little window that lets you see the bits and extractors. Opening the case is okay, but when closing it the bits all get hung up in the window so the case won't close. You have to close it carefully so this doesn't happen. Lesson learned. I threw the kit out.

It got the job done I suppose. The drill bits aren’t the sharpest or the most durable. One of the drill bits was worn out in about 60 seconds with cutting oil and made less than a mm of progress. I ended up drilling out the bolt with a different brand drill bit (in under 15 seconds) and only using the extractor portion from this kit.

I got my hands on the Screw-Extractor and Left-Hand Drill-Bit Set, and it's been an absolute game-changer for my automotive repair work. The set's durability and performance have been nothing short of impressive, and it's a clear winner compared to the name-brand extractors available at major retail stores. The best part? It comes at a fraction of the cost. Using it to extract bolts from vehicles has been a breeze, thanks to the effective left-hand drill bits and screw extractor. It grips onto stubborn bolts firmly, making removal a quick and efficient process without causing any damage to the surrounding components. The affordability of this set is what initially caught my eye, and after putting it to the test, I can confidently say it's worth every penny and more. The quality of the materials used is top-notch, and even with frequent use, I haven't encountered any signs of wear or breakage. In the unlikely event that something does go wrong, I wouldn't hesitate to buy another set. This product has earned a permanent place in my toolbox, and I highly recommend it to anyone in need of a reliable and cost-effective bolt extraction solution.

This is a great value high quality set. If you take your time and drill slowly you won’t have troubles with broken bits. Automobile engine bolts are tough. If you take your time drilling out the pilot hole you won’t have troubles.

نوعيه تعبانه جدا

Extremely sharp drill bits that seem to stay sharp too. The extractors don’t bite very well, and chewed up the steel studs instead of removing them. Ended up drilling the studs out.

Onestamente non mi sono servite, non le consiglio perché non mi hanno risolto il problema.

Excelente marca

These are well made and did the one job that I scheduled for them in seconds. The left handed thread drill bit actually took the broken bolt out without using the easy out. I just followed directions and did not force the bit beyond its tensile strength.
