UPDATED 26Oct2018: Sometimes a tool surprises you. That’s the case with a hole saw I used for a job that was well beyond what this tool was designed for. It had to do with one of my old tractors. Sometimes a situation demands that you push a tool far beyond what it was designed for, and this was one of those times. I needed to get to a starter motor mounting bolt that was hidden behind lots of steel. I could easily get a wrench on this bolt if only I had an access hole, but there was a big frame in my way. Click below to watch a video tour of the job, and how an unlikely tool bored a 2 1/8″ diameter hole through more than 3/4″ of solid steel.
