GRS 003-683 Microblock Ball Vise Without Attachment Set

Part # 103.683 4 In Stock Weight -- lb -- g
Current price $425.00

The GRS 003-683 MicroBlock Ball Vise is machined from solid stainless steel and finished with a special low-glare treatment to reduce eye strain during extended work sessions. Designed to deliver solid work support in a compact, highly maneuverable package — slightly larger than a baseball — the MicroBlock is an ideal choice for stone setting, small engraving jobs, and other precision bench work. Its low profile and compact footprint make it especially well suited for microscope work or any situation where a larger vise would be an obstacle.

The smooth self-centering jaw system securely holds workpieces with consistent alignment, while an adjustable internal brake system allows the user to dial in rotational resistance anywhere from completely free-spinning to fully locked. The working surface is oval shaped, measuring 40 mm × 43 mm.
