Jura by GRS 502-504 Brass Collet Set of 11 with Radius Divider JURA MH.BC.11 

These brass collets are stronger than the standard nylon collets and that can make a difference for some engraving applications. But that is not the only reason Jura makes this set.

The main reason for the brass collet sets is they are used in the production of fishtail settings.  The set of 11 brass collets also include a 90 Degree Marking Guide.  This tool sets inside the collets when you are using the collets straight up in the Jura M6 Plate using the Jura M6-30 countersunk screw (part of the Jura Master Set of Tools and the Jura Basic set of tools).  With the 90 Degree Marking Guide you can make precise straight marks on the side of your band so when is comes time to do your cuts your lines will be straight and true.

 

This tool is for advanced stonesetters and is not introduced to Jura students until they have gained the necessary skills to successfully use the tool.
