About
Complete 4-Step Rock Tumbling Grit Kit: Includes the grit, polish, and media needed for a full 4-step tumbling cycle: 1 lb Step 1 60-grit coarse silicon carbide, 1 lb Step 2 150-grit medium silicon carbide, 0.5 lb Step 3 600-grit fine silicon carbide, 0.5 lb Step 4 1200-grit aluminum oxide polish, plus 1 lb ceramic tumbling media to help balance the barrel, cushion stones during tumbling, and support more consistent polishing results.
Made for More Tumbling Projects: This 4 lb refill kit provides enough grit, polish, and media for up to 25 lb of rocks, helping you keep multiple batches moving without buying each stage separately. A practical value refill for hobbyists, collectors, classrooms, families, and KomeStone K4 users.
Ceramic Media for Smoother Results: The included ceramic media helps fill the barrel, balance the load, cushion stones, and distribute grit more evenly during each stage. Reusable ceramic media can be cleaned between steps and used across multiple tumbling cycles.
Easy 4-Step Use on Popular Stones: Follow your tumbler manual for exact loading. As a general starting point, use about 2 tablespoons, approximately 25-30 g, of grit per 1 lb of rocks for each stage, add water just to the top of the stones, and tumble about 3-9 days per step. Suitable for agate, jasper, quartz, sea glass, gemstones, and other lapidary materials.
Pairs with KomeStone and Most Tumblers: Designed as a refill and add-on kit for KomeStone K4 and most rotary or vibratory rock tumblers, from starter models to larger-capacity machines. Ideal when starter grit runs out, when preparing the next batch, or when keeping extra supplies ready for ongoing polishing projects.
Build Your KomeStone Polishing System: This 4-step kit is complete for a regular tumbling cycle; for hobbyists, collectors, and users who want a finer, more refined finish, KomeStone supports serious rock tumbling projects with a broader grit and polish line. Explore optional ultra-fine polish powders such as 8000, 12000, and 17000 grit, plus red cerium oxide for compatible lapidary materials, to continue polishing beyond the standard 4-step process.
