We're suspecting this is as old as my grandma, but it's still cool. It's a dual-bit drill: you just flip the next bit into place when you're done with the first one. Perfect for countersinking then screwing in stuff, I suppose. Any other potential uses for this high-tech hyrda-like drill?
Oh, and it also kind of looks like a dong and costs $119.
