Description

The 7 lb. GRS® MicroBlock® XL allows you to access your piece from almost any angle. The smooth self-centering jaw system (2-3/4”, 70mm max. opening) is great for detailed engraving and stone setting. An internal brake system ensures a strong, steady grip. The vise is machined from solid stainless steel and finished with a special low-glare treatment to reduce eye strain.

Microscopic Work
A low profile makes the MicroBlock® XL ideal for exacting tasks with the aid of a microscope. The vise configuration provides stability for your work and allows quick and easy positioning adjustment of your piece without changing the alignment of the microscope or its field of view. You can even adjust it without taking your eyes from the microscope.

GRS® 520 Accessory Set
This accessory kit allows you to hold virtually any piece in the MicroBlock® XL while you work. All components are organized in an easily accessible organizer tray made of high-impact plastic molded to accommodate each component. Includes:
• 8 small pins
• 4 flat square pins
• 4 thick round inset pins
• 8 round rubber-coated pins
• 2 rectangular inset-curve plates
• 2 leather-faced ring clamp plates
• 4 3" Thermo-Loc® sticks

Thermo-Loc® is a special reusable polymer fixturing compound that's rigid at room temperature and becomes pliable when warmed. It is ideal for holding irregularly shaped or fragile items. Its medium-gray color helps reduce eye strain under work lights. The material is non-toxic and biodegradable.
