it would have to be ground that way, I have seen that before. carbide will break before being bent. they can move around alittle in a collet but they wont bend. I have seen them where the cutting edge was not concentric to the shank. but it is very rare.

I would say if you had a bent bit, it was high speed steel. Carbide breaks
