A lot of the times you can use a flat head to remove the inner part. Better to break the bolt than strip a very expensive pan, I believe they're hollow for this exact reason.
@@Andrewactual Thank you very much. I ended up being able to just unscrew mine without a bit. I tried a reverse screw, but my drill wasn't giving enough rotation. The torn screw started to unscrew anyway as the drill helped it turn. I shoulda tried that before hand...
