Got a 5/16 bolt that sheared off and need to drill out. Tried several bits to drill it out and all they did was make a shiny spot. Never had much problem in the past drilling bolts out. Are there better bits that could be used in this situation or is there a way to take the hardness out of the bolt?
Can you take the hardness out of bolt.
