Rock Tumbling Grit Kit for Soft or Hard Stones 6 Grades of Grit & Polish(6

Contains Six varieties of Popular grit and polish. Use this Grade A tumbling grit to help you get the best tumbler results for hard or soft rocks in a rotary tumbler. We provide you with two extra grit grades to cover your needs with hard or soft rocks. This allows you to do some extra tweaking to improve your results with various types of rock. First, we include a Silicon Carbide grit graded at 46/70 to prep your harder stones. This grit also scores better results for any stone as it covers a wider spectrum of tumbling at the first stage. Second comes a material to run two pre-polish steps, the first is with a more durable Aluminum Oxide 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 final Polishing stage using micron level Aluminum Oxide Fine polish. Having these extra grit grades will allow you to do more experimentation and have more success with your finished product. 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! .
