Watch and Learn How to Remove a Broken Bolt with Drill Press! I provide all of the details on properly drilling a broken bolt out.
Spark Notes:
- Use Center punch
- use small drill bit to start the hole
- Use New High Speed Drill Bit
- Use Proper Feed and Speed (some drill presses have settings for this)
- Drill 1 Drill Bit size under the Sized of the Threads.
- Make sure its centered and drill all the way through the bolt
- If the hole was perfectly centered through the bolt, then drill with the final size of the bit before tapping the Threads
- pick out the threads and Tap the threads 2 times
