Lasts up to 100 times longer than standard sandpaper. Small but tough sanding tasks for removing old material and preparing surfaces are almost impossible to accomplish with conventional sanders or by hand. Even if you can reach the surface, the sandpaper tears. However, with the Expert Sanding Plate, you can reach corners and sand difficult materials using your oscillating multi-tool. With Bosch Carbide Technology, grains of the hardest metal are securely attached to the surface. This sharp grain remains highly effective throughout its long lifespan as it can be cleaned with solvents. The Expert Sanding Plate is designed for multiple materials and applications. The coarse, open grains of RT2 (grain 20) are best suited for removing mortar behind tiles, carpet adhesive, or for rough processing of wood. RT4 (grain 40) is ideal for removing thick paint but can also handle mortar and adhesives. RT6 (grain 60) is the paint specialist, while RT10 (grain 100) is perfect for sanding and preparing clean wood surfaces. Starlock attachment for maximum power transfer and convenient blade changes within 3 seconds. Material: Carbide-RIFF, Diameter: 90 mm.
