Shape gold, silver, copper, and other malleable metals into sheet, square wire, and half-round profiles with one versatile rolling mill. Cnc-machined gears and a 1:2 hand-crank ratio deliver precise, repeatable results, while a T-bar finely adjusts roller spacing from 0.1 to 7 mm. High-quality 45# steel rollers resist pressure and wear, and the heat-treated body carries a rust-resistant coating for lasting corrosion protection. Multiple square and half-round groove sizes let you dial in the exact dimension a project calls for. A comfortable crank handle keeps extended sessions easy on the hands. Bundled accessories, including a silver polishing cloth, jewelry silver rod, and agate knife, mean no extra tools are needed. Suited to K gold, 925 silver, aluminum, and more, it serves both professional jewelers and Diy makers crafting bracelets, rings, and bangles.
