20 RPM Precision Rotation: Engineered with a slower 20 RPM drum speed ideal for rock polishing and lapidary work, allowing stones to tumble properly for smoother edges and more consistent finishing results.
Stainless Steel Construction: Built with stainless steel components for corrosion resistance and long-term durability, giving this rotary rock tumbler the strength to handle abrasive grit and repeated polishing cycles.
Large 17 lb Capacity: Commercial-grade 17 pound drum handles larger batches of rocks, stones, and jewelry pieces, increasing efficiency for serious hobbyists and professional lapidary use.
Rubber Lined Drum: Heavy-duty rubber lining reduces operational noise and cushions stones during tumbling, protecting materials while improving comfort in workshops and studio environments.
Industrial Strength Build: Matte black powder-coated base, heavy-duty rods, and ball bearings support stable rotation under load. Backed by a 3-year warranty on the base and drum plus limited 1-year motor coverage.
