Ring sizer by Durston 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. Two matching dies are provided. The tool features six splines on its polished steel mandrel, ensuring exceptionally accurate ring sizing. This sizer will size 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.

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).
