ToolUSA Professional Jeweler's Ring Stretcher and Size Reducer (SKU: TJ9795A) stands as an indispensable tool. This heavy-duty apparatus is thoughtfully designed to seamlessly adjust the size of plain bands, ensuring the utmost accuracy during operations. Featuring a robust weighted base, this ring stretcher and reducer guarantees stability during use. It's crafted to mount effortlessly onto workbenches, aided by pre-drilled holes in its base. The intuitive "dial-a-size" sizing wheel facilitates easy size selection. Once the ring is positioned correctly, the lever can be used to lower the mandrel, gradually altering the ring's size. Though robust in design and function, it's essential to note that this device is most effective on plain bands and not recommended for rings with stone settings.
