Shape and polish gemstones with precision using a 180W 100% copper-wire motor that runs smoothly from 0 to 2980 Rpm, backed by adjustable speed control and a low-noise design for a comfortable workspace. A high-efficiency manipulator with a 96-gear mechanical handle polishes gems at multiple angles and heights, moving up and down for smooth rotation, reduced shaft wear, and flexible control. Built from rust-resistant stainless steel with a compact, elegant structure, every precision component is made to hold up through years of use. An adjustable lamp on an independent switch swings to different angles for a brighter line of sight, while removable baffles simplify cleanup and keep your station tidy. Three interchangeable grinding heads handle cutting, carving, drilling, grinding, polishing, cleaning, and descaling, making it suitable for jewelry, jade, stone, wood carving, gold, and dental work.
