Our AIR-TIP™ dust collector collects dust as you work with its rubber seal that maintains suction to a wall for less cleanup time later. After connecting the dust collector to a wet/dry vacuum, it uses the vacuum's suction so you can attach it to a wall for hands-free work. You can cut or drill above the funnel design while the vacuum is on to capture more debris. The rubber seal maintains suction throughout the application so you can put less dust in the air, on the ground and free up a hand that would otherwise be holding a vacuum nozzle. The Milwaukee AIR-TIP™ dust collector is compatible with other wet/dry vacuum brands with 1-1/4, 1-7/8, 2-1/2 in Dia and is part of the AIR-TIP™ family of trade focused vacuum accessories.
