A 5/8" end mill should have been used to open the first 1/4" as a "pilot guide hole" and then a 5/8" drill bit to finish it.
Rather than show the mistake of not clamping the vise to the table they proceeded to make each other look stupid. It seemed real flaky to me like after the mishap they quickly shot a "beginning scene" stating "don't break the drill bit".
Stupid is forever but ignorance can be fixed. I have worked in and around machine shops all of my adult life and motorcycle shops too. I once saw somebody severly injure themselves (SEVERED HAND) because they had a pair of gloves on. They were ignorant, nobody told them to not wear gloves around machiney, band saws included. Jesus forgives, machines don't.
Somewhere out there is a good hearted beginner that probably wanted a drill press for Christmas. A good imported one isn't that expensive and they are a very handy addition for any do it yourselfers garage. Guys wife is now thinking of how dangerous one is, hubby won't get one for Christmas.
Discovery Channel could do better with the reality TV concept, mistakes are part of life but they should have shown how to prevent them, how to learn from them.
