Reduce harmful airborne dust particles while drilling in walls and ceilings with the Metabo 2-3/4" Vacuum Dust Extraction Adapter (631343000). It features a unique, two chamber system with a foam rubber gasket that keeps it attached to even and uneven surfaces, such as plaster, natural stone, and woodchip wallpaper. The adapter extracts dust at the hole entry point for a safe and dust-free work environment, while also minimizing dust residue left on the work surface.
