{"product_id":"grs-003-773-microblock-xl-engraving-vise-100mm","title":"GRS 003-773 MicroBlock XL without Attachment Set","description":"\u003cp\u003eThe GRS MicroBlock XL 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 allows the user to dial in rotational resistance anywhere from completely free to fully locked.\u003c\/p\u003e\n\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 MicroBlock XL is an excellent choice for stone setting, small-to-medium engraving, and other precision bench work.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExpanded size and weight relative to the original MicroBlock — bridges 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\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e003-773\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBlock Weight\u003c\/th\u003e\n\u003ctd\u003e7 lb (3.18 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBall Diameter\u003c\/th\u003e\n\u003ctd\u003e3.9 in (100 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eJaw Width\u003c\/th\u003e\n\u003ctd\u003e1.8 in (46 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eJaw Height\u003c\/th\u003e\n\u003ctd\u003e0.87 in (22 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Opening\u003c\/th\u003e\n\u003ctd\u003e2.75 in (70 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\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\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eAdding part \u003cstrong\u003e#103.775\u003c\/strong\u003e (sold separately) converts the MicroBlock XL into a positioning vise.
