The Jura by GRS 500-006 Microblock Jaw Set is a precision replacement jaw set designed for the GRS MicroBlock, featuring 3/32" (2.35mm) pin holes throughout. Purpose-built for diamond setters and stone-setting professionals, this jaw set offers a more practical alternative to the standard GRS MicroBlock jaw set, which uses tops with nine 3.8mm diameter holes and three threaded holes per jaw side.
The 3/32" shank diameter is the industry-standard size for jewelry bits and burs, making this jaw set immediately compatible with the tools already in your bench kit. One of its key advantages is the ability to repurpose modified, worn, or broken 3/32" diameter burs as custom jigs for holding workpieces during setting — extending the life of your existing tooling and expanding your setup options.
Important: This jaw set is designed for use with JURA tool holders that fit into the GRS MicroBlock. A GRS MicroBlock fitted with either the basic JURA attachment set or the complete JURA attachment set is required for use.
