{"product_id":"grs-003-773-microblock-xl-engraving-vise-100mm","title":"GRS 003-773 MicroBlock XL without Attachment Set","description":"\u003cp\u003eA heavier ball vise gives an engraver the mass to take a hard hit without the block shifting under the graver. The \u003cstrong\u003eGRS 003-773 MicroBlock XL\u003c\/strong\u003e from Glendo GRS is an expanded, heavier version of the original MicroBlock vise, designed to fill the gap between the GRS MicroBlock and the GRS Standard Block. Weighing 7 lb (3.18 kg) with a 100 mm ball diameter, roughly the size of a softball, it delivers the mass needed for hard-hitting engraving work while remaining compact and maneuverable enough for precise, delicate control. Its low profile makes it well suited for use under a microscope, and the internal rotational brake system lets the user dial in rotational resistance anywhere from completely free to fully locked.\u003c\/p\u003e\u003cp\u003eBecause the MicroBlock XL uses the same jaw system as the original MicroBlock, it is fully compatible with all existing MicroBlock attachments, including Jura Microstonesetting Tools. Adding part #103.775 converts it into a positioning vise for even greater versatility. Two bases, one rubber and one plastic, are included to give the user options for control and feel across different work surfaces. The jaws are 46 mm wide and 22 mm tall with a maximum opening of 2.75 in (70 mm), making the MicroBlock XL an excellent choice for stone setting, small-to-medium engraving, and other precision bench work.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eExpanded size and weight relative to the original MicroBlock, bridging the gap to the GRS Standard Block\u003c\/li\u003e\n\u003cli\u003e100 mm ball diameter provides stability with a compact, low-profile footprint ideal for microscope work\u003c\/li\u003e\n\u003cli\u003eInternal rotational brake system adjustable from free rotation to fully locked\u003c\/li\u003e\n\u003cli\u003eCompatible with all MicroBlock attachments, including Jura Microstonesetting Tools\u003c\/li\u003e\n\u003cli\u003eAdd part #103.775 to convert to a positioning vise\u003c\/li\u003e\n\u003cli\u003eIncludes both rubber and plastic bases for versatile surface control\u003c\/li\u003e\n\u003cli\u003eSuited for stone setting, small-to-medium engravings, and precision work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAll MicroBlock attachments, since the XL uses the same jaw system as the original MicroBlock\u003c\/li\u003e\n\u003cli\u003eJura Microstonesetting Tools\u003c\/li\u003e\n\u003cli\u003ePart #103.775 (sold separately) to convert the block into a positioning vise\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eWhat you get:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMicroBlock XL Vise\u003c\/li\u003e\n\u003cli\u003e4 Pins\u003c\/li\u003e\n\u003cli\u003e1 Rubber Base\u003c\/li\u003e\n\u003cli\u003e1 Plastic Base\u003c\/li\u003e\n\u003cli\u003e1 Plastic Hex Key\u003c\/li\u003e\n\u003cli\u003e1 Wrench\u003c\/li\u003e\n\u003cli\u003e6 Screws\u003c\/li\u003e\n\u003cli\u003eThermo-Loc Sample Kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAdding part \u003cstrong\u003e#103.775\u003c\/strong\u003e (sold separately) converts the MicroBlock XL into a positioning vise.
