Made by Kagan, known throughout the jewelry industry for quality, this tool rolls across stone-set ring shanks (or plain bands), working and enlarging the ring without disturbing the prongs on the setting(s). Select a grooved roller die that will match the width of your ring shank; the grooved die provides uniform pressure on the shank as it rotates against the smooth roller die for perfect stretching with no distortion. Eight polished roller dies are included (four grooved and four smooth) that accommodate ring shanks in half-round, knife-edge and flat styles up to 5mm wide.
This enlarger can also be used as a mini rolling mill. Simply feed wire through the desired size in a grooved die, using one or more passes, as needed, to shape the wire.
This enlarger is heavy and features four countersunk holes that allow you to fix it securely to your work surface (hardware is not provided). An illustrated instruction sheet is included.
