Powered by a 180W 100% copper-wire motor, this lapidary polisher runs at a steady 0-2800 Rpm with adjustable speed regulation and quiet operation for a comfortable working environment. A high-efficiency manipulator with a 96-gear mechanical handle lets you polish gems at multiple angles and heights, adjusting up and down for smooth rotation and flexible, straightforward grinding. Rust-resistant stainless steel and a compact, elegant structure keep every precision component durable through long hours of work. A built-in drain pipe carries away water promptly, while removable baffles cut down on splashing, reduce pollution, and make cleanup easier. Three interchangeable grinding heads cover cutting, carving, drilling, grinding, polishing, cleaning, and descaling, so the machine suits jewelry, jade, stone, wood carving, gold, dentures, and handicraft work. A bag of triangle abrasive is included to get you started right away.
