Well, that’s new. Or not. We’ve been able to drill square holes since 1917. Neatorama discovered in Harry Watts’s patent how the first model looked like. I must admit that it came as a sort of surprise because you don’t get to see everyday this kind of drill.
Let’s see it in action:
And here is the concept explained in a nice animation. So, basically you need to drill on two axes in order to move the drill head around. Simple and in the same time a genius idea. Since the concept is almost one hundred years old I might say that the guys back then were damn good. At least at drilling, electricity and… well, pretty much a lot of things 😀
