Query: The best experience with these diamond tips was

I am new to this tool and have been experimenting with a variety of different tips. I have extensive experience with larger stone polishing tools. The best experience with these diamond tips was, as I expected, on stone. In a tray of water, dipping them in often, sometimes with the stone and tip just at the water surface, I carved designs into granite with results that gave me a smile.
