Rock Tumbler Grit - Lapidary Abrasives. Rock tumbling grit is a silicon carbide powder with a Mohs hardness of 9.25. That is much harder than the types of rocks that are commonly tumbled. Coarse grit is used to shape the rocks, then progressively finer grits are used to smooth their surface and prepare them for polishing.

It will also eliminate the worst of the bumps, pits, and so on. Most rock tumblers will use the coarse grit for about a week, at which point you can remove the rocks from the resulting slurry.

Lately we are skipping the fine grit step completely on some of our tumbling. The rocks go from medium grit in a rotary tumbler to polish in a vibratory tumbler (we do all of our polishing in vibratory).

One batch of these is all you need to last quite a while as they can be reused. Also, pellets should only be used in rotary tumblers – never in vibratory.
