Impressive. I thought before seeing this that a broach,pritchel, plasma arc and a water jet were pretty much it.

Someone had to be thinking outside the square or is that inside the square to come up with that.

At least they did it , then for sure there will be a way to do it in a harder material , mather of time .
I can only say that this is very impressive .

I know this is an old thread but square hole drilling has been around for 50 years or longer. I ran a radial drill that squared the holes in the u joints for Cat grader shafts back in the mid 60s and I don't think it was a new process then.

I missed this the first time around. I can't imagine the stresses that machine must go through moving the tool that fast!
