GRS® MicroBlock® One Ball Vise

Engineered for a perfect balance of stability and maneuverability, the MicroBlock One offers the same trusted work support and maneuverability as the original MicroBlock—at a more accessible price. Designed with a self-centering jaw system and a low-profile design, it is ideal for stone setting, small engravings, and other detailed work under a microscope. The internal rotational brake system allows you to set the rotational resistance anywhere from free to locked, giving you control exactly when you need it. A simplified bearing system provides smooth operation while keeping the design cost-effective and durable.

Features:

  • Self-centering jaw system – Automatically centers workpieces for secure positioning during stone setting, engraving, and microscope work
  • Low-profile design – Fits comfortably under microscopes for unobstructed visibility and access to detailed work
  • Adjustable rotational brake – Set resistance anywhere from free movement to fully locked for exact control when needed
  • Simplified bearing system – Smooth, reliable operation with cost-effective durability

While the MicroBlock One is designed to fit under a microscope, you can always use with the Micro-Block Step Risers (sold separately) to bring this up to a different working height when your needs change.  Sold in a set of 5, each riser is 1/2" high and made of heavy, durable plastic.
