This is a professional quality rock tumbler with a metal drive unit and a overload-protected motor. This rock tumbler will polish gemstones and rocks from their original rough appearance to a smooth, polished finish by tumbling with a succession of abrasive grit powders (available separately - see Thumler's Rock Tumbler Polishing Grit Pack #300). The kit includes a 3 lb. capacity tumbler bin and 5 extra replacement "O" rings. This kit is definitely a step up from other available rock tumblers which are cheaper and more toy-like with corresponding quality. |
