Enhance the roughest rock processing in step 1 by starting with our extra coarse 46/70 grit and following this with our coarse 60/90 grit. The use of two grit grades covers a fuller spectrum of abrasion during the initial process potentially shortening subsequent steps 2 through 4. We use the highest grade pre-polish and polish for these steps.
The kit includes enough media to tumble a full load of rock in a 3 pound rotary tumbler. The materials can also be used in other sized tumblers with simple ratio adjustment.

The tumbling process for rocks uses a four step process with two passes in step 1 and these abrasive and polishing materials. The following five items are included.

One 3 oz. package extra coarse Silicon Carbide (46/70 grit) used in Step 1A
One 3 oz. package coarse Silicon Carbide (60/90 grit) used in Step 1B
One 3 oz package medium Silicon Carbide (120/220 grit) used in Step 2
One 1.5 oz package pre-polish Silicon Carbide (500 grit) used in Step 3
One 1.5 oz package polish Aluminum Oxide (Fine – micron sized) used in Step 4

The abrasive media is shipped in separate plastic re-closable bags.
