Use this Grade A tumbling grit to get the best tumbler results for softer rocks such as agates and jaspers in a rotary tumbler. We provide you with material to run two pre-polish steps, the first is with Silicon Carbide 500 grit, then a finer pre-polish  of Aluminum Oxide 1000 pre-polish. This dual step process for pre-polishing sets your rocks up for maximized results in the Polish stage using micron level Aluminum Oxide polish.
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 grit and polish amount in this listing is offered with
free shipping!
