Made in England by Durston, this ring sizer delivers excellent versatility! This quality-made tool offers ring stretching and reducing as well as bending and shaping of half-round, flat, oval and engraved shank material (up to 4mm thick) into circular rings. It is effective on even the heavy-weight hard alloy metals.
The tool features six splines on its polished steel mandrel, ensuring exceptionally accurate ring sizing. This sizer accommodates non-ferrous precious and non-precious metal rings and bands up to size 14 (U.S.). Its countersunk, polished steel, reducing plate will reduce bands up to 12mm wide. A matching die is included.
The body is cast iron, powder-coated for long service life, and the base (4-5/8"W x 7"D x 1-1/8"H) is drilled with four countersunk holes (7.5mm dia.) for mounting securely to your work surface (hardware is not included).
This sizer is not appropriate for sizing rings or bands made of hard metals such as steel and titanium.
