GRS MicroBlock Engraving Block Ball Vise

Like larger GRS engraving blocks, the GRS MicroBlock Ball Vise is machined from solid stainless steel and finished with a special low glare treatment to reduce eye strain. The Microblock was designed to provide solid work support in a small and maneuverable ball vise. The smooth, self-centering vice jaw system is perfect for stone setting, small engraving jobs, and other precision work. An adjustable internal brake system allows the user to select just the right amount of rotational resistance - from totally free to fully locked and anywhere in between.

The Microblock's low profile and compact design are especially suited for microscope work or other circumstances where the size of a larger vise may obstruct work. Available with or without the GRS Engraving Attachment Set (see related products below). Includes wrenches, four 9/64" steel pins, 6 screws, plastic base, 1 plastic hex key, and a sample of Thermo-Loc fixturing compound. Made in USA.
