Product Details

GRS 003-774 MicroBlock XL with 30 Piece GRS 103.520 Attachment Set

The GRS MicroBlock has been expanded to give it additional weight and functionality.  The new MicroBlock XL is a 7 lb (3.18 kg) vise with a 100 mm ball diameter.  It is the perfect size between the GRS MicroBlock and the GRS Standard Block.  By utilizing the same jaws from the MicroBlock, the XL version allows compatibility with all your favorite MicroBlock attachments, including Jura Microstonesetting Tools.  The MicroBlock XL comes with two bases, one plastic and one rubber, for increased control and better feel.  The small and maneuverable vise is great for stone setting, small to medium size engravings and other precision work.  The internal rotational brake system lets the user choose the amount of rotational resistance from free to locked.  The MicroBlock XL's low profile is suited for microscope work.

This version includes the GRS 30 piece 003-520 attachment set.
