That stuff is super easy to dril as in you could use a screw driver to manually drill a hole if needed although not recommended just an example showing how easily worked they actually are. When you start your project i would just be sure to have a sacrificial wood backing to fully support the back side which should help eliminate any "Break out" damage from happening. Also if drilling multiple holes like you stated i would probably use a predrilled wooden "jig" just to help keep things neat and Last but not Least If i remember correctly the Dust created from working those firebricks are not good to breathe so make sure you use a proper dust mask.
