Festool 578959 Sanding Block HSK-Duo 80x133

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. A double-sided hook and loop interface lets abrasives attach securely and swap out quickly. Work with control: choose between a hard or soft foam side to match the surface and sanding task Maintain crisp edges: the hard side provides firm backing for flat surfaces and defined edges Follow curves easily: the soft side adapts to contours and profiles for a smoother finish Reduce dust at the source: when paired with Granat Net abrasives, dust is captured within the abrasive Change abrasives quickly: double-sided hook and loop allows fast, tool-free changes Reach tight areas: perfect for detail work where machines can’t fit Reusable design: durable construction keeps the block in use—just replace the abrasive Sized for 80 x 133 mm abrasives; ideal for fine work, touch-ups, repairs, and hard-to-reach areas.
