I was trying to find out exactly what is happening in this video when I stumbled on the below video, and then it was off to the races. 30 minutes later, if they ever want to make a Shame-like movie about heavy tool machine porn, I'm available and sufficiently prepped. My brain about melted when I realized the drill wasn't spinning.
The other video is 6 minutes of a blade cutting through steel with a soundtrack by the London Philharmonic, and it's quite meditative to watch. (via @chrissandoval)
Here's another slow motion drill with sparkles. Cripes. It might be better.
