Festool Sanding Block HSK-Duo 80×133 578959

Get more control in hand sanding with a dual-sided block designed to adapt to your work. The HSK-Duo features both a hard and soft foam side, giving you the flexibility to sand flat surfaces, contours, and profiles with the right level of support. Use the hard side when you need more control and crisp edges. Switch to the soft side to follow curves and ease edges without digging in. The lightweight design keeps it comfortable in hand, even during extended use. With a double-sided hook and loop interface, abrasives attach securely and swap out quickly—so you can move from coarse to fine without slowing down. Paired with Granat NET abrasives, dust is captured at the surface, helping reduce airborne dust even when sanding by hand. Ideal for fine work, touch-ups, repairs, and hard-to-reach areas where power tools can’t go.
