MicroBlock XL


The GRS MicroBlock® has been expanded to give it additional weight and functionality. The new MicroBlock XL is a 3.1 kg vise with a 100 mm ball diameter. It is the perfect size between the GRS MicroBlock and GRS Standard Block. By utilizing the same jaws from the MicroBlock, the XL allows compatibility with all your favorite MicroBlock attachments. It also comes with two bases, one plastic and one rubber, for increased control. The small and maneuverable vise is great for stone setting, smallto- 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. Its low profile is suited for microscope work.
