When working on cars one of the most difficult problems I can remember is dealing with broken bolts, taps or easy outs. Broken bolts can be anywhere on the car. It can be broken manifold bolts, head bolts, transmission bolts, accessory… really anywhere. The problem is the same no matter where the bolt is. Removing the broken bolt without damaging the threads if possible and moving on to complete the job. When removing a broken bolt, it’s best to use a center punch to mark the center of the broken bolt. This helps prevent the drill bit from walking off to the side so you can drill down the center. Using a left handed drill bit is a good idea. And it’s a good idea to keep some left handed drill bits handy just for this purpose. When drilling the center of the broken bolt with a left handed drill bit, sometimes the bit can catch the bolt and spin it out of the hole. This can happen if the bolt is just broken and the threads are still good and not crossed. If the bolt comes out your problem is solved. If the bolt does not spin out when using the left handed drill bit, an easy out (EZ Out) broken bolt extractor can sometimes be used. The EZ out can sometimes grab the broken bolt and remove it. Be careful though. Sometimes people put too much force on an EZ out and it can break off too. It’s anything but easy to remove. The metal compound that drill bits, EZ out bolt extractors and thread taps are made of is very hard and brittle. A regular drill bit cannot drill into them. There are companies that base their entire business on broken tap and extractor removal. They use specialized equipment to disintegrate the broken material. These are companies are are hard to find and sometimes the entire piece has to be removed, stripped and shipped to them for removal of the broken piece. It is simply not feasible to remove an engine, and ship a bare block to a company to remove a broken piece of tooling. We have been selling the rescue bit. The rescue bit looks like a normal bit, but the metal compound is harder than what’s used for drill bits, taps and easy outs. What it can do is truly amazing. Check out the video to see what it does. It’s definitely worth a try before seeking out a specialty broken tooling removal company and possibly having to ship a heavy piece half way across the country.
