IRWIN Screw Extractor for Spiral Screws, 5-Piece (53535)

The size of the spark plug: m14 (check for yours in the official website, most cars have m14 though)The number of extractor: 5 (biggest one)The head(very important, I was looking for the right head for 6 days): 3/8 drive(drive doesn't matter I guess, just use for whatever drive you have), 3/8 size, 12 point socket! It fits very well, I've also rounded extractor's tail(the part that goes into the socket) with one layer of thin paper towel.Long enough extension that plugs into the sockets head.Ratchet(technically not needed that much, as you shouldn't put that much pressure on it)Steps. I had been soaking the thread for about 2 days with wd 40 (2 times per day, few drops of it, nothing crazy). At the day X, I've decided to get PB Blaster, sprayed it, waited for maybe 3-4 hours and began the process. Basically you take your tool with the extractor attached and a hammer. Hammer it down LITTLE BIT, don't even try to put a lot of strength, and start to turn counter clockwise, at first it can slide little but, but don't stop and keep turning it(I did it with my hand until I felt that extractor actually grabbed the thread and that is where I've put a ratchet and kept turning. In my case it was very smooth and I could almost do it with 1 hand, so if you feel big pressure, please stop and put more PB Blaster or whatever you use. And keep going like that slowly.Good luck

I was working on my KTM motorcycle replacing the front sprocket when I snapped the bolt on the countershaft. Doh!! I was able to drill the hardened metal with my Irwin cobalt drill bits. (Another great Product) and I tried using some cheap easyouts which didn't work well at all because the bolt had lockite red on it. I knew this was going to be next to impossible to remove.I called my KTM dealer and they quoted me a replacement of the countershaft assembly and 8 hours of labor to split the engine case to replace the countershaft for $1200.00. I was like – No Way! So I started researching other options. I read on a forum where someone had the same exact issue as me and having success with this style of extractor.I found these here on Amazon and since they were Irwin brand which is a brand of quality tools I trust so I bought this $10 set of extractors. I got them the very next day I ordered them and I used one of the extractors and hammered it in as deep as it would go and it grabbed tight enough that I was able to remove the remaining bolt without touching the threads on the countershaft. Whoo Hoo!These work very well! Just buy a set, trust me they are worth having in your tool box!

Next to impossible to tell from the photos, but the Irwin bit is on the left with a bit from a Neiko made in China but on the right. If they’re in your hands you can feel the difference in machining, sharpness, etc. The Chinese extractors feel so dull/ smooth that I’m doubtful they’ll be very useful.Unfortunately, the Irwin doesn’t come with drill bits or a handy way of storing these besides in the clear plastic they came in. Also, without a storage bin you have to read the labeling on the bits themselves which is very very small and will likely wear off pretty quickly, which makes selecting the right bit complicated.However, at the end of the day I want it to work correctly. If you have a stuck screw or bolt or whatever, you know that the cost of whatever will solve your problem is usually completely secondary to the PITA you will be facing if you can’t extract the stripped component. So, what I may do is combine the Irwin into the Neiko set with drill bits and keep the Neiko extractors as spares.So, 5 stars for the bits, at least compared to the competition.But 4 stars if you are considering ease of storage, organization and overall headache factor.

I snapped one screw while changing a gasket on my car. I said now the DIY will cost more and more but watched a few videos and found this item.Other alternatives contained drilling bits as well. I said I need this item once in a blue moon and drilling bits that I have should do the job. After breaking one bit, I managed to make a deep dent on the screw and used the smallest extraction bit which didn't work. So tried the second smallest and it took the broken screw easily. So, I would say don't worry about the size indicators on bits getting erased some time later, it is a trial and error operation, not a precise drilling operation.I used my electric drill for the whole operation and it worked fine for me. Nice addition to my tool box which I have no idea when I ever will need it again. So I am glad that I bought this item which was cheap and consumes no space... Recommended to give a try for sure.

I knew better! I have a 10mm bolt broken off and was able to drill through it. Used the smallest bit and dropped/lost it in gravel. Next one up? Re drilled and had NO problem until the screw metal gave way. Re drilled and made it go deeper. Using a quarter inch handle managed to grip tight enough but I broke it! The tool did was it was supposed to do! If your drilling 10mm? Just drill it out and Re tap! My bad. I knew this and did it anyway. I am NOT unhappy with the tool. It gripped and tried to work but just too small of my force and it broke! This is the nature of hardened steel. Now I am completely effed! Again MY BAD CUZ I KNEW BETTER! These are really nice extractors and certainly will do what I need in the future. Would I repurchase? Absolutely!Would I ever try such a small bolt? HE DOUBLE TOOTHPICK NO!

Ive tried to use these and between the drilling out and trying to get these to bite ive had no luck.
