So all you need to do now is make a thin walled core drill out of solid granite and then use that thin walled granite core drill bit to drill a hole in solid granite.
You can use quartz if you like. A quartz thin walled core drill.
Let us know when you've done it.
You can only use copper tools to make the granite or quartz core drill, because you don't have a granite core drill yet.
BTW scratching isn't cutting is it.
