Tumbling grit
I’ve only used the first tumbling grit for the rough rock so far and they’re still tumbling—but even though it says it’s coarse—it doesn’t seem as coarse as some I’ve seen demonstrated on YouTube.
I ordered four different grit sizes and like I say, I can only speak about the first one because that’s the only one I’ve tried.
Perhaps there are different degrees of coarseness in the coarse grit??
