MJR Tumblers Rock Grit Kit for 15 lb Tumbler

Product Description:

Comes with FREE Polishing Instructions

We use a superior blend of Green/Black Silicon Carbide for our first stage. Green Silicon Carbide is of higher purity than Black Silicon Carbide, therefore it will work faster than Black Silicon Carbide because it’s harder and stays sharper longer.

MJR Tumblers offers a large selection of heavy duty tumblers, a full range of silicon carbide grit (50, 80, 60/90, 500, 600, 500/600 and 1500) and aluminum oxide (400/600 and 1200). These can be purchased individually in any weight denomination that fits your needs or we have pre-made kits for your specific size tumbler. We have kits available with or without plastic pellets.
