At 7 lb (3.18 kg) with a 100 mm ball diameter, it fills the ideal size gap between the GRS MicroBlock and the GRS Standard Block. The XL version retains full compatibility with all standard MicroBlock jaws and attachments — including Jura Microstonesetting Tools — so your existing tooling investment carries over without compromise.\u003c\/p\u003e\u003cp\u003eThe MicroBlock XL is well suited for stone setting, small-to-medium engraving work, and other precision tasks. Its low profile makes it particularly compatible with microscope setups. An internal rotational brake system allows the user to dial in resistance anywhere from completely free-spinning to fully locked, providing precise control throughout the work. Two bases — one rubber, one plastic — are included to optimize grip and feel across different work surfaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThis version includes the GRS 003-520 30-piece attachment set\u003c\/strong\u003e, expanding the versatility of the block right out of the box.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eExpanded MicroBlock design with added weight for greater stability and control\u003c\/li\u003e\n\u003cli\u003e100 mm ball diameter positions it between the MicroBlock and Standard Block in size\u003c\/li\u003e\n\u003cli\u003eCompatible with all standard MicroBlock jaws and attachments, including Jura Microstonesetting Tools\u003c\/li\u003e\n\u003cli\u003eInternal rotational brake system with adjustable resistance from free to fully locked\u003c\/li\u003e\n\u003cli\u003eLow-profile design suited for microscope work\u003c\/li\u003e\n\u003cli\u003eIncludes both rubber and plastic bases for versatile surface control\u003c\/li\u003e\n\u003cli\u003eBundled with the GRS 003-520 30-piece attachment set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\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\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\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\u003cli\u003eGRS 003-520 30-piece attachment set\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Glendo GRS","offers":[{"title":"Default Title","offer_id":43583655936214,"sku":"103.774","price":635.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/grs-003-774-microblock-xl-with-30-piece-grs-003-520-attachment-set-otto-frei-1.jpg?v=1719956567","url":"https:\/\/www.ottofrei.com\/products\/grs-microblock-xl-vise-003-774-30-piece-003-520-attachment-set","provider":"Otto Frei","version":"1.0","type":"link"}
