Closeout Jura by GRS 500-006 Microblock Jaw Set with 3/32" Pin Holes

A jaw set drilled with pin holes lets a setter build custom holding jigs right on the block instead of working around fixed jaw faces. The Jura by GRS 500-006 Microblock Jaw Set is a precision replacement jaw set for the GRS MicroBlock, carrying 3/32" (2.35mm) pin holes throughout. It is purpose-built for diamond setters and stone setting professionals, and is a more practical option than the standard GRS MicroBlock jaw set, whose tops use 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, so this jaw set works with the tooling already in the bench kit. Modified, worn, or broken 3/32" burs can be repurposed as custom jigs for holding workpieces during setting, which extends the life of existing tooling and widens the holding options.

Features

• Replacement jaw set engineered specifically for the GRS MicroBlock
• 3/32" (2.35mm) pin holes, the standard diameter for jewelry bits and burs
• Allows reuse of modified, worn, or broken 3/32" burs as holding jigs
• More versatile for diamond setting work than the standard GRS MicroBlock jaw set
• Made for JURA tool holders that fit the GRS MicroBlock

Compatibility

Designed for 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; the tool holders and attachment sets are acquired separately if not already owned.

Notes

This jaw set is an accessory for an existing MicroBlock setup rather than a complete holding system.
