No its not strictly a square hole as the corners are rounded. Check mine out which gives a truly square hole.

@Woodomain Well, this one really is also a true square! Can you send me details of your's. I'd be interested to see it.

Well, I saw the idea. I didn't see a square hole.

The idea is some what similar to a rotary engine... remarkable

Depends on the situation. If you want to put a square stick through it, it makes a huge difference. I wouldt call it a square, I would say its close to a square.

@Bluemchenwiese1 "Huge" ?! we don't need really square at all, the corner are not usefull !

[Bluemchenwiese1]

But the hole will not be square. It will be square with round edges^^ Thats a huge difference

100% totaly useless . a thousand sized holes == a thousand sized cutters. try doing that in inconel or stellite. nice gimmick . we have edm now its the 21st century

I remember seeing this on Qi, your video's would be the perfect thing to be featured on that show. Nice work! :)

All I see is a rotating cam. Where's the drilling?
