How to choose grit & polish kits
A standard tumbling run uses a coarse grit, a medium grit, a fine or pre-polish grit and then a polish. A kit covers the stages in the right order, and buying grit by stage lets you restock only what you use. Clean the barrel and stones thoroughly between stages so coarse grit does not scratch the polish.
