This is actually quite easy. Just take your time and make sure you don't break anything. You'll need a good straight shot at the stud. Room to move helps.
Tools requires
- Stud Extractor
- Corresponding size drill bit
- Reversible Drill
Parts Needed
- Replacement stud or bolt.
Time Required
- approximately 5 minutes
Steps
- Make sure you have a good clean shot at the stud. There needs to be at least enough room for the drill and your hands.
- I bought the 10 piece stud/bolt/screw extractor kit from Sears. (case + 5 extractors + 5 drill bits).
- If you want to (I would highly recommend it), replace the bits in this kit with reverse drill bits. Occasionally, the reverse drill bit will be all that is needed to pull the broken stud out. With regular bits, you'll be trying to drive the stud farther in. Make sure they are extremely strong as regular drill bits may not cut the mustard. Remember, you will typically be drilling into a hardened metal. You don't want to break the bit off in the stud you are trying to extract.
- Soak the stud with WD-40/PB/Liquid Wrench/your favorite lubricant.
- Use a center punch to make a small indentation in the center of the broken stud. This will do two things.
- It will create a small dent for the drill bit to sit in so it won't wander as you try to drill it out.
- It may break the grip of the metal to metal and loosen the stud ever so slightly.
- Using the appropriete size drillbit for the stud, drill a hole into the stud. Be careful you don't hit any threads or drill too deep.
- At this point, if you used a reversible drill bit, the stud may have come out with just the drill bit. Otherwise, you will need to use the stud extractor. More lubrication around the threads as best you can, and by all means, clean out the metal shavings so they don't lodge in the threads and cause it to lock up. Using the corresponding extractor bit, set the drill on reverse and "drill" into this new hole. The extractor will go into the stud and lock in place. The reason it is reversed is so the stud comes out without damaging the threads.
