Looks like the Chinese got ahold of an old Harry Watt bit from the 60's and went to town. Wink

I've heard of bits that could do that, but never seen it in action. Obviously a press is a must as that chuck looks a bit off center. Pretty cool stuff.

The chuck is elliptical, yes. Works like a Wankel engine.

They seemed to have solved the main issue with the Watt mortise bit which is that it left a very small rounded corner, so even though you used it you still had hand work afterwards. That's why you would normally use a chisel bit like so:

It still leaves rounded corners, the holes are too small to see them, but check out the diagram. They are very minute, but still rounded. Wink
