Lasts up to 100 times longer than standard sandpaper - Small but hard sanding jobs to remove old material and prepare surfaces are almost impossible to do with conventional sanders or by hand. Even if you can reach the surface, the sandpaper will tear. With the Expert Sanding Plate, however, you can reach corners and sand difficult materials with your oscillating multifunctional tool. With Bosch Carbide Technology (Bosch Carbide), grits of the hardest metal are firmly attached to the surface. This sharp grit remains highly effective over its long life because it can be cleaned with solvent. The Expert Sanding Plate is designed for multiple materials and applications. The coarse, open grit of the RT2 (grit 20) is best suited for removing mortar from behind tiles, carpet adhesive or for rough sanding wood. The RT4 (grit 40) is best for removing thick paint, but it can also handle mortar and glue. The RT6 (grit 60) is the paint specialist, while the RT10 (grit 100) is ideal for sanding and preparing clean wood surfaces. Starlock attachment for maximum power transmission and convenient blade change within 3 seconds. Material: carbide RIFF, diameter [mm]: 116
