Yes, of course I did a fine grid on the bits.

In addition, I tested the bits on another working model. I had a rigid drill that cut concrete and I added deformable bits to it. All the same. When rotating, they experience enormous stress:

I also tried using the classic contact workbench, it doesn't help.  and i also tried using rigid body additional nodes to connect the bits and the drill, that doesn't help either
