Durston Ring Stretcher & Reducer

The Durston Ring Stretcher & Reducer (9.5 kg) is a professional jewelry repair tool designed to enlarge, reduce, and reshape ring bands with precision. Built with a heavy-duty steel frame, this bench tool allows jewelers to resize rings quickly while maintaining the integrity and shape of the ring shank.

The tool uses a tapered expanding mandrel to stretch rings to a larger size and a reducing plate with multiple polished dies to decrease ring size or reshape distorted bands. This dual-function system makes it a versatile solution for jewelry repair workshops and manufacturing benches.

Weighing approximately 9.5 kg, the machine provides excellent stability during operation, ensuring smooth and controlled resizing. The heavy construction and hardened components allow the tool to withstand frequent professional use.
