GRS Microblock™
Ball Vise
for engraving, stone setting and other precision work
|
The new GRS Microblock™ Ball Vise is the latest product
in a broad line of precision work-holding tools. Like larger GRS vises, the Microblock
is machined from solid stainless steel. It is finished with a special low glare
treatment to reduce eye strain.
This new vise was designed for a unique
combination of solid work support in a small and maneuverable size.
The smooth self-centering jaw system is 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.

GRS Positioning Vise
Especially made for Microscope Work
This unique vise has many Magnablock similarities and one huge difference: you can reposition its center of rotation. In the photo above, the upper part of the vise is off-center to the right.
By pulling the release lever, you can slide the upper half back to the left until it is centered, or even further until it is off to the left. After moving, it will rotate about its new position.
Why is this important?
Under a microscope, your work must stay in the field of view as you rotate the vise or you can’t see it. Using a traditional engraver’s block, this only happens when the work is near the center of the jaws.
Often, this becomes an impossible limitation. The Positioning Vise lets you move the center of rotation by simply pulling a lever. In seconds, you can reposition your work to rotate within the microscope’s field of view.
Even without a microscope, there’s another big advantage. This vise weighs a massive 42 lbs. The extra weight and larger base provide even more stability.

GRS Low Profile Vise
Stability and Reduced Height
Some work needs a lower vise height. The Low Profile model
offers GRS strength and quality in a shorter model. A popular use is under a
microscope where 6" (150mm) of space is needed between the microscope and the work.
Using other blocks, the eye level of the user can be too high. The Low Profile Vise has the
same jaw size and capacity as the Magnablock, yet is 1.5" shorter.
An option for this vise is a heavy-duty turntable base shown at right.
