Festool Sanding Block HSK-Duo 80x133

Pre-order now for shipment starting September 23, 2026.

With hard and soft foam faces, the HSK-Duo adapts to flat surfaces, contours and profiles. The hard face provides firm backing for controlled sanding and crisp edges, while the soft face conforms to curves and profiles without digging in.

Its lightweight construction is comfortable to hold during extended sanding. Hook-and-loop faces hold abrasives securely and make grit changes quick. Used with Granat NET abrasives, it captures dust at the sanding surface, helping reduce airborne dust. It is well suited to fine work, touch-ups, repairs and areas difficult to reach with a power sander.
