How did they bend? or are those new and that's part of the manufacturing process...

I would guess it's part of the process, but it looks like it was cylindrically ground, and it would seem that it should be precise from that.

Are you sure that this is used for drilling into bone? How does it cut? It does not look like any drill bit.
