Jura MH.11 Brass Collet Set of 15 with Radius Divider 15mm to 22mm

Jura by GRS 502-504 Brass Collet Set is a professional-grade set of 11 brass collets ranging from 15mm. Designed specifically for advanced stonesetting applications — including the production of fishtail settings. This is the original 11 piece version of the set.

Unlike standard nylon collets, these brass collets offer greater strength and rigidity, which can make a meaningful difference in demanding engraving and stonesetting applications. The increased durability of brass allows for more precise control when working with the Jura M6 Plate system.

This tool is intended for advanced stonesetters. Jura does not introduce this tool to students until they have developed the necessary skills to use it successfully.
