The GRS® Ring Size Cutter simplifies ring sizing by removing an exact amount of ring shank. The cut is precisely to size and always parallel, ensuring neat and fast soldering. Say goodbye to uneven or inaccurate cuts—this tool gives jewelers the precision needed to achieve clean results every time. The cutter also allows the use of the removed plug for future up-sizing, helping reduce material waste and saving on sizing stock.

This professional-grade ring cutter is made in the USA and comes with seven interchangeable cutters in the following USA sizes: 1/2, 3/4, 1, 1-1/4, 1-1/2, 1-3/4, and 2. Each cutter corresponds directly to the size you wish to remove. For example, using the 3/4 cutter will reduce the ring by exactly 3/4 of a size. Cuts are parallel and precise, which makes the soldering process easier and more reliable.

The GRS Ring Size Cutter is ideal for gold and silver rings only, and can cut rings up to 2mm thick and 8mm wide. It should not be used on platinum, stainless steel, or titanium rings. Securely mount it to a sturdy bench or workstation before use, and always wear appropriate safety gear when cutting metal.

Built from hardened, heat-treated steel components, this tool is designed to withstand long-term use in professional workshops. It’s a smart investment for jewelers who frequently perform ring resizing services and want clean, consistent results.

Also available in a metric version with 9 metric-size cutters (sold separately under part number 104.643).
