Ben from UncharteredX has a good video on these drill samples, but does not buy into the mainstream acceptance of how they were made. In fact the granite core samples show continuous grooves and you can calculator the pressure per turn the mechanism was under, and it’s not really able to be done easily.https://youtu.be/KFuf-gBuuno
