People can drill holes in rock with slow speed drills. Even Jade is worked with hand tools.

There is a difference in the drill marks left by a low speed and a high speed drill going through a given material - If that isn’t enough ... many have tried to duplicate the results with both methods of ancient drill holes and the high speed won in the cases claimed.

If you can’t figure the truism out then that’s your problem.
