{"product_id":"festool-578959","title":"Festool HSK-Duo 80x133 Dual-Sided Hand Sanding Block 578959","description":"\u003cp\u003eThe Festool HSK-Duo 80x133 Dual-Sided Hand Sanding Block (578959) is a versatile manual sanding tool engineered for precise control across flat surfaces, curved contours, edges, and profiles. Featuring a dual-density foam design, the sanding block combines a firm hard foam backing on one side with a pliable soft foam backing on the opposite side. It accepts 80 x 133 mm (3.14 x 5.23 in.) abrasives via a double-sided StickFix hook-and-loop interface, allowing woodworkers and finish tradespeople to tackle detailed manual surface preparation where power sanders cannot reach.\u003c\/p\u003e\n\n\u003cp\u003eThe dual-density foam backing provides tailored control depending on workpiece geometry. Using the hard side offers firm support for sanding flat surfaces and maintaining crisp, sharp edges. Flipping to the soft side allows the block to conform to rounded profiles, curves, and easing edges without gouging or digging into the material. The double-sided hook-and-loop surface holds abrasive sheets securely and enables tool-free grit changes. When paired with the included Granat NET abrasive mesh sheets, sanding dust is drawn into the net structure during manual sanding, keeping the surface cleaner and extending abrasive life.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-Density Foam Construction:\u003c\/strong\u003e Features a hard foam side for flat surfaces and a soft foam side for contours and profiles.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFirm Edge Control:\u003c\/strong\u003e Hard backing side maintains rigid support to keep edges sharp and surfaces flat.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContour Conformity:\u003c\/strong\u003e Soft backing side adapts smoothly to curves and rounded sections to prevent material gouging.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble-Sided StickFix Interface:\u003c\/strong\u003e Hook-and-loop fastener on both sides secures abrasives and enables fast, tool-free grit changes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDust-Reducing Net Compatibility:\u003c\/strong\u003e Captures dust within the mesh structure when used with Granat NET abrasives.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eErgonomic Lightweight Design:\u003c\/strong\u003e Contoured body reduces hand fatigue during extended manual finishing and touch-up work.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable Reusable Block:\u003c\/strong\u003e Built for long service life in daily shop or jobsite use by simply replacing worn abrasive sheets.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e(2) Granat NET 80 x 133 mm P80 Abrasive Mesh Sheets\u003c\/li\u003e\n  \u003cli\u003e(2) Granat NET 80 x 133 mm P120 Abrasive Mesh Sheets\u003c\/li\u003e\n  \u003cli\u003e(1) Granat NET 80 x 133 mm P180 Abrasive Mesh Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eChoose the HSK-Duo 80x133 (578959) for maximum manual sanding flexibility across flat and contoured surfaces without requiring an attached extraction hose.
