This GRS® MicroBlock XL offers a smooth self-centering jaw system and is perfect for precision work, such as fine detailed engraving and stone-setting. The MicroBlock XL features an internal brake system that ensures a strong, steady grip as you work. The vise is machined from solid stainless steel and finished with a special low-glare treatment to reduce eye strain. This MicroBlock XL includes a Thermo-Loc® sample kit (containing two 6" sticks of the material) and a 14-piece accessory kit with four pins, two bases (one rubber, one plastic), a plastic hex key, an Allen wrench and six screws.
Thermo-Loc® is a special reusable polymer fixturiing 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. This material is non-toxic and biodegradable.
