The Festool HSK-Duo Dual-Sided Hand Sanding Block, 80x133 (model HSK-Duo 80x133) gives you two working surfaces in one tool: a hard foam side and a soft foam side, so you're not switching blocks every time the job changes from flat panel work to a rounded edge or profile.\u003c\/p\u003e\n\u003cp\u003eThe hard side is built for control. Press it against a flat surface or an edge and it holds its shape, which keeps corners crisp instead of rounding them over the way a fully soft pad can. Flip to the soft side for curves, mouldings, and profiles, and the foam flexes to follow the contour instead of bridging over it and missing the low spots. Having both in one block means you can move between flat and shaped work on the same piece without reaching for a second tool.\u003c\/p\u003e\n\u003cp\u003eBoth sides use a hook-and-loop interface, so abrasive sheets attach securely and pull off just as easily. That's what makes fast grit changes possible — go from a coarse sheet to a fine one in seconds, with no adhesive residue to scrape off between changes. Sized for 80x133mm abrasives, the block is compatible with Festool Granat, Granat Net, and Rubin abrasive lines.\u003c\/p\u003e\n\u003cp\u003ePaired specifically with Granat Net abrasives, this block helps manage dust even during fully manual sanding — the net-style abrasive captures dust within itself rather than letting it all become airborne, which matters in a finished space where you can't just run a shop vacuum. The block ships with five sheets of Granat Net abrasive to get started: two P80, two P120, and one P180, covering a rough-to-fine progression for a typical repair job.\u003c\/p\u003e\n\u003cp\u003eMade in Switzerland and built to be reused indefinitely — the block itself doesn't wear out, only the abrasive does — this is the right tool for cabinetmakers, finish carpenters, and refinishers doing touch-up work, edge easing, or detail sanding on profiles and corners where a power sander is the wrong tool for the job.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\u003csummary\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"tnincluded-wrapper\"\u003e\u003cul\u003e\n\u003cli\u003e(1) Festool HSK-Duo dual-sided hand sanding block, 80x133\u003c\/li\u003e\n\u003cli\u003e(2) Granat 80x133 P80 GR NET abrasive sheets\u003c\/li\u003e\n\u003cli\u003e(2) Granat 80x133 P120 GR NET abrasive sheets\u003c\/li\u003e\n\u003cli\u003e(1) Granat 80x133 P180 GR NET abrasive sheet\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-key-specifications\" class=\"acc\" open\u003e\u003csummary\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003ctable class=\"aplusspecs\"\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/weight.svg\" alt=\"weight\" class=\"aplusicon\"\u003e Weight\u003c\/th\u003e\n\u003ctd\u003e0.94 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/size.svg\" alt=\"size\" class=\"aplusicon\"\u003e Block Dimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e3.11-in x 5.19-in x 1.53-in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/specs.svg\" alt=\"specs\" class=\"aplusicon\"\u003e Abrasive Size\u003c\/th\u003e\n\u003ctd\u003e80 x 133 mm (3.15-in x 5.24-in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/tool-free-change.svg\" alt=\"tool-free-change\" class=\"aplusicon\"\u003e Attachment System\u003c\/th\u003e\n\u003ctd\u003eHook-and-loop, both sides\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/grit-range.svg\" alt=\"grit-range\" class=\"aplusicon\"\u003e Included Abrasive Grits\u003c\/th\u003e\n\u003ctd\u003eP80, P120, P180 (Granat Net)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/made-in.svg\" alt=\"made-in\" class=\"aplusicon\"\u003e Made In\u003c\/th\u003e\n\u003ctd\u003eSwitzerland\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-compatibility\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"compat-list\"\u003e\u003cdiv class=\"compat-row\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/compatible.svg\" alt=\"\" class=\"icon-sm\"\u003e\u003cdiv\u003e\n\u003cstrong\u003eAbrasive System\u003c\/strong\u003e\u003cdiv class=\"compat-detail\"\u003eFestool Granat, Granat Net, and Rubin abrasives, sized 80x133mm\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-applications-uses\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eBuilt For\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"tags\"\u003e\n\u003cspan class=\"tag\"\u003eWoodworking\u003c\/span\u003e\u003cspan class=\"tag\"\u003eCabinetry\u003c\/span\u003e\u003cspan class=\"tag\"\u003eFurniture Refinishing\u003c\/span\u003e\u003cspan class=\"tag\"\u003eRemodeling\u003c\/span\u003e\u003cspan class=\"tag\"\u003eDetail \u0026amp;
