GRS Positioning Vise & Extras. GRS' largest, heaviest, and top of the line vise. Vise is in good condition.Comes with Allen wrench key. And 2 other unmarked tools. I took the jaws off to fit in a flat rate box.
The following information I found at. Similar to the MagnaBlock, the Positioning Vise from GRS has one very unique difference: a positionable center of rotation.
While working under a microscope, this is an important function that allows the workpiece to remain centered in the field of view. This detail saves time while working. As the largest vise made by GRS, the extra weight and a larger base provides the most stability and adjustability available. Includes upper jaw plates, 5 pins, base, 1 plastic hex key, and wrench.
(19.1 kg) Ball Diameter: 7.1" (180 mm) Jaw Width: 3" (76 mm) Jaw Height: 1.8 (46 mm) Max. Opening: 3.5 (89 mm). Product Manuals & Available SDS. I got this and many other engraving tools from an estate of an old gunsmith. Check out my other engraving tools and vises.
