It's hard to get a close look at the holes in this vid but it looks like there may still be small radiuses in each corner, so not a true "square" hole

#4 there are, but the rest of the edges are perfectly straight. And no real corner is really infinitely sharp and neither are square bars that go in these holes.

Anyway, this defies common sense, so it qualifies as awesome!

Check out this interactive demonstration.

Its not a drill as its starting with a pre drilled 10mm round hole.

Also these days they can cut square holes in metal in a fraction of the time with high power laser cutters.

Amazing but Still am not convinced its a perfect corner

#1 & #10 This vid is Chinese,not Japanese ,and the technique has been around in the US for decades. I think this is an old video.

#12: If this video is Chinese, why is it in Japanese? Chinese written language has no curly characters. The Japanese however use traditional Chinese characters alongside with their own alphabet.
