GRS 003-683 Microblock Ball Vise-Without Attachment Set

 The GRS MicroBlock is machined from solid stainless steel and finished with a special low glare treatment to reduce eye strain. Designed for a unique combination of solid work support in a small and maneuverable size, slightly larger than a baseball. The MicroBlock has a smooth self-centering jaw system perfect for stone setting, small engraving jobs and other precision work. An adjustable internal brake system lets the user choose the amount of rotational resistance from totally free to fully locked and anywhere in between. The MicroBlock’s low profile and compact design is especially suited for microscope work or other situations where the size of a larger vise is an obstacle. Included with the MicroBlock is the support base, 2 sticks of thermlock, 6 hex nuts, 4 holding pins, and 2 hex keys. The working surface is oval shaped and measures 40mm x 43mm. 

The GRS Microblock weighs 4 lbs (1.8kg) with a ball diameter of 3.1" (80mm) a jaw width of 1.8" (46mm) and a jaw height of 0.87" (22mm). The maximum diameter opening of the jaws is 2" (50mm). The GRS microblock stands 3.375" tall when placed on its plastic base.
