Drill Out Broken Fastener and Extractor
At 7:19 in
I Screwed Up BIG TIME on This One...
What happens here
Faced with a broken extractor embedded in the bolt, the strategy shifts to drilling the entire fastener out. The presenter explains that after the initial 3/16 inch bit and extractor failed, they proceeded to use a series of larger drill bits (stepping up from 5/64ths to 15/64ths, skipping bits that broke) to gradually enlarge the hole and remove the remaining bolt material along with the broken extractor. This process effectively destroys the original threads but removes the obstruction.
Goal: Since the extractor broke, switch to drilling directly through the broken bolt and the embedded extractor using progressively larger drill bits until the remaining metal can be removed.
