Larger Precision Ball Vise for Jewelry Engraving, Stone Setting & Microscope Work The GRS MicroBlock® XL Vise provides the perfect balance between compact maneuverability and increased workholding capacity. Designed for professional jewelers, engravers, stone setters, and precision craftsmen, the MicroBlock XL expands on the original MicroBlock® design with a larger 100 mm ball diameter, increased weight, and greater jaw capacity while maintaining the low-profile design preferred for microscope work. Built for detailed engraving, stone setting, and small-to-medium-sized projects, the MicroBlock XL features a self-centering jaw system that helps position workpieces quickly and securely. The integrated rotational brake system allows users to adjust movement from smooth free rotation to a locked position, providing complete control while working from multiple angles. With compatibility across the entire MicroBlock® accessory family, the MicroBlock XL offers exceptional versatility for professional workstations while remaining easier to maneuver than larger traditional engraving blocks.
