14 Pieces Screw Extractor Set, Left Hand Drill Bits Set for Removing Stripped Screws and Broken Bolts 35# Cr-Mo & 6542 HSS Steel Cobalt Easy Out Screw Extractor Set Broken Bolt Extractor Kit

Recently I picked up an older 1999 Toyota 4runner from my buddy who had bought it new and finally bought a new car. He didn't want the 4runner any more and just gave it to me. I always like it so I thought this will be fun to bring back to like new shape. Truthfully it was really well maintained by my friend. But he had at some point backed into something and dented the left rear bumper corner. So I picked up a used one off of Ebay that I thought was painted the correct color. Well it arrived and I set it aside to wait until a bit warmer weather to remove and replace the damaged piece. After starting the project I learned the paint didn't match. So the drama began. Ordered pain etc. Prepped and painted the thing. Then guess what that color was wrong. So after a call to the paint place they helped me get the right color and shipped me a new batch. Okay part is painted and I finally get it bolted onto the car. Then I am in the final stretch and as I start to attach the wheel well flare piece that is part of the limited 4runner series on these years, I noticed I could not start one of the three fastener bolts? Upon closer inspection, I discovered the original fastener was still in the threaded hole and the head was broken off. Hells bells, now what? So off the part comes and I order a vice grip and some penetrating oil. Those arrive and the bolt is just stuck like it is welded! Mind you the piece isn't rusted. Well from here I tried a small tap and die set I had to no avail. I finally looked up on Youtube and saw you can use left hand drills to remove bolts with sheared off heads. So this was my last ditch effort before ordering a new part and more paint etc. BTW I am into this little repair for now about $180.00 so I am starting to think I should have just paid my deductible and had the insurance fix the little dent. But then this kit arrived. And I thought here goes nothing. Well shocker! I used the smallest bit first and got a good pilot hole started, then went in with the next larger bit. About 2/3 of the way into the bolt the bit caught and turned the rest of the bolt out of the hole. I was ecstatic! Hooray! This is just a great little set of very affordable bits that is a must have for any tool collection.

Worked like a charm, strong material and strong threads

I had a valve cover blot snap off in my engine block. The ultimate horror. It was well below the surface of the mating surface of the valve cover and so I had no choice but to try to extract it. I saw a few reviews about this product breaking and so I was worried but ordered anyway as it had the highest positive reviews. Well, the kit worked and I got that bolt out. That probably saved me a few grand (shop would’ve charged me a fortune to rescue my engine block). I used a cheap old Harbor Freight Hercules hand drill on its fastest setting with the kit’s smallest left-hand drill bit (about 3mm diameter). I drilled in reverse in 10-second bursts with breaks to ensure that the drill bit didn’t get too hot. I used a mini vac to vacuum up the resulting metal shavings (open engine block ports covered with rags and tape to ensure that nothing got in the engine). Once I got down about half and inch, I semi-gently hammered in the left-hand gripper tool until it bit, and then used an adjustable wrench to slowly turn the broken bolt out, spraying with PB Blaster line as I went. The broken bolt came right out. The whole process took about 30 mins (I went slowly on purpose; because if it went wrong, my engine block would’ve been toast). I am a real human being, not a bot. This product worked for me and it was my first time using. Just use it right and it should get the job done. Saved me a lot of time and money. I hope this review helps someone else out who’s panicking in a bad situation like I was.

This was a better purchase than using the Ryobi brand screw extractor from HomeDepot! I used this kit so far on just one exhaust manifold stud and there is no damage to the tool itself. The Ryobi brand from HomeDepot was damaged on the first stud I ever tried to remove. I would definitely recommend this kit or the price as it's not often you will use a tool like this.

I went from the ultimate "DIY high" to a complete heart-stopping panic in a matter of seconds. I had just finished what I thought was a successful afternoon of work, replacing the valve cover and the intake hose on my car. I was feeling proud of myself for taking on the project and saving money on labor—until I picked up the torque wrench for the final step. In a moment of exhaustion or just pure rookie oversight, I made the massive mistake of setting my torque wrench to 89 ft-lb instead of the required 89 in-lb. For those who don't know, that is 12 times the amount of force the bolt is designed to handle. Before I even realized what was happening, I heard that sickening snap. Then another. By the time I stopped, I had 5 snapped bolts buried deep in the engine valve head. The panic was real. I called around to a few local shops, and the quotes were devastating: at least $900, plus the cost of towing the car to the shop because it was completely undrivable. I felt like I had just turned a simple maintenance task into a financial disaster that might require a whole new engine if the threads were ruined. I decided to try this left-hand extractor set as a last-ditch effort, and honestly, it felt like a miracle. If you are in this position, do not panic—just follow this process: Center Punch is Key: I used a center punch to create a clean, deep dimple right in the middle of each broken bolt. This is critical because it keeps the drill bit from sliding and scratching the aluminum engine head. Slow and Steady: I set my drill to its lowest speed setting. Reverse Direction: I used the left-hand bits in reverse (anticlockwise). As I applied firm, steady pressure, the bits bit into the hardened steel, and I actually saw the bolts start to unscrew themselves. Within 30 minutes, I had all 5 broken studs out of the engine without a single scratch to the original threads. This set saved me nearly $1,000 and the headache of a week-long shop repair. If you’re a first-timer, triple-check your units—inch-pounds are very different from foot-pounds! But if the worst happens, this tool is the best insurance policy you can buy. Highly recommended!

In all, I was able to get the job done, but I had to use another set of drill bits. These were trash! The extractor worked great. Just make sure you buy a good set of still bits along with this kit.

Super duper happy with this! You all know the feeling in the pit of your stomach when you break a bolt head! I was able to get a stubborn bolt stub within an hour of getting this kit! Key is to start small, progressively go to the largest drill (spinning in reverse) and then use the extractor corresponding that bit. A couple of the s all bits broke, but I don’t mind it at all, it got the job done.

This tool worked the magic needed. The only criticism is the the directions leave a little to be desired! When using the one of the extraction bits, one must definitely drive it into the broken bolt with a hammer. This step is critical to seat the extraction bits!
