This heavy duty ring stretcher is a precision tool designed for reshaping and resizing metal rings with accuracy and ease. Built to handle everyday use in a busy workshop, it allows you to stretch or reduce rings without distorting the band’s shape or pattern.
Marked clearly with UK ring sizes B through Z+5, this versatile tool is ideal for jewellers working across a wide range of sizes. The stretcher mandrel features evenly tapered splines for smooth, controlled expansion, while the shrinker dies compress the ring band evenly to maintain its round profile. Reducing does often result in a slightly domed appearance to your ring however.
Perfect for gold, silver, copper, brass and bronzes this dual-function tool is an essential bench companion for both resizing and fine adjustments.
These pictures show our workshop ring sizer bolted firmly to a sturdy benchtop which is essential to getting the most from your ring stretcher.
