What's that sticking in my neck?
Why it's part of #54.(055 dia) drill that I just broke.
Lesson: If you notice any flex on a small drill correct the problem.
When I backed out to clear chips and started back into the hole I noticed the drill bit jump a little indicating that it wasn't lined up. What the the hell I thought. It's in the mill and I spotted with a center drill it couldn't be off that much. Well I was wrong. In combination with the misalignment, and failure to adequately clear chips, the bit broke. When it did I felt a piece hit my neck. I thought nothing of it until several minutes later I felt my neck and felt something. Sure enough, a small shard of the broken bit was embedded in my neck. Luckily my wife was able to pull it out with tweezers.
This also reinforces why safety glasses should always be worn. If it would have hit my eye, this would have been a bad story.
