Holds up to 100 times longer than standard sandpaper. Small but tough sanding tasks for removing old material and preparing surfaces are nearly 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 with your oscillating multifunction tool. Bosch Carbide Technology securely attaches the grains of the hardest metal 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 (grit 20) are best suited for removing mortar behind tiles, carpet adhesive, or for rough sanding of wood. RT4 (grit 40) is ideal for removing thick paint but can also handle mortar and adhesive. RT6 (grit 60) specializes in paint, while RT10 (grit 100) is perfect for sanding and preparing clean wood surfaces. Starlock attachment for maximum power transfer and convenient blade changes in just 3 seconds. Material: Carbide-RIFF, diameter: 90 mm.
