How do I extract a bolt after I broke a bit inside the bolt when preparing to use a screw extractor? |
Hi, I was working on my motorcycle when I broke a bolt off inside a stud on my bike frame. I went to the hardware store and purchased a screw extractor and a small drill bit. To make a long story short the small bit broke inside the bolt. The question of the day now is how do i still get the bolt out with the drill bit stuck inside of it? Any ideas? If there is any stub of the drill bit left, get a needle nose vise grip pliers and try to back it out. Or, you can try a sharp, small chisel or a center punch and try tapping the bolt shank out by hitting it off center to rotate it out. Use plenty of light oil to lubricate the threads. Don't try to rush the job. Take your time. Source(s): Been there, done that and it sucks. dynamite I can't really picture your situation exactly, but I've seen products on TV, QVC for example, that extract bits. I'm thinking that's what you purchased at the hardware store, though. Try drawing a picture of the problem and taking to the hardware store to ask the pros for suggestions. what size is the bolt... i am guessing about a twelve millimeter. the frame is light alloy so this is serious you could weaken the frame. if the bolt was big enough weld a nut on the end of it and then use a wrench to turn the nut which is welded onto the broke bolt. if you can get a left twist drill bit it might turn itself out as it is trying to drill it you can always drill it out and tap the hole for a larger bolt. Depending on the hardness of the steel in your frame you can get a small Oxy torch with a very small tip and slowly melt the bit out of the broken bolt. |
