GRS 003-684 MicroBlock Complete with 30-Piece GRS 003-520 Attachment Set

The GRS MicroBlock Ball Vise is machined from solid stainless steel and finished with a special low-glare treatment to reduce eye strain during detailed work. Designed to deliver solid work support in a compact, maneuverable form — slightly larger than a baseball — the MicroBlock is ideal for stone setting, small engraving jobs, and other precision bench tasks.

The smooth self-centering jaw system provides reliable, consistent grip, while an adjustable internal brake system lets the user dial in rotational resistance anywhere from completely free-spinning to fully locked. The MicroBlock's low-profile, compact design makes it especially well-suited for microscope work or any application where a larger vise would be an obstacle.

This set includes the MicroBlock vise with support base, plus the GRS 003-520 30-piece attachment set. The attachment pins fit the upper jaw plates of all GRS vises, expanding versatility across a wide range of holding and setting tasks.
