What the Scanning Electron Microscope Reveals About This Failed Drill

Today we're going to analyze the drill that broke last week while drilling in aluminum. We'll take a look at it under the microscope, and then take advantage of a friend with a Scanning Electron Microscope to look at the morphology of the break, and do some elemental analysis. Because science. Also, because Clough42.
